Bill Sohne delves into the intriguing appearance of a rare white dial Omega Railmaster, a 'white elephant' that surfaced on eBay. He uses this event to pivot into a broader discussion on collecting philosophy, breaking down a watch's appeal into its dial, case, and movement. Sohne's insights offer a structured approach for collectors to evaluate and appreciate their timepieces.

Hello everyone

It has come to my attention ( multiple PMs and emails ) That a White dial Railmaster  popped up on ebay.  I knew about this example in early Aug as the seller contacted me after reading the following post , I am including a link to the original article and its is also pasted in this post for easier reading.   The seller emailed me that he was buying such a watch from a local in his area ( I feel bad for the local seller) and asked what mine was worth , I said please send pics of your example as I am not talking about my watch, i also wanted to really confirm it was a ck 2777-2.   This went on for a while and then he did not reply for almost two months.  Then 12 days ago he came back with the same questions and no photos.  I refused and then the last message I got from him was  " its on ebay" .   After looking at the auction photos that were not great for determining if I would spend " a lot " of money ... On a side note  It amazes me the number sellers that post poor quality photos and looking to get "top dollar".  I know some potential  buyers tried to contact the seller requesting closeup and better pics and was treated to "' no more photos ." type of a reply...   i bet the seller lost some bidders !!  Possibly the price could have been higher .


This the second example of a white dial railmaster that I have come across ( the other is the example in my collection).  To keepq it simple an all original White dial Railmaster will have a 1)  CK 2777-2 case ref  2)  The case would not have fix bar , standard spring bars fo fit a leather strap  3) will have a Swan neck 283 caliber movement .  To be honest I was watching the auction also and I would have loved to comment on it while the auction was going , but we all have rules to follow . 


instead of focusing on the WDR  ( White Dial Railmaster) lets take a step back and just talk about collecting.  We all have rules on what to collect or why you like one watch more then another , you might not even  realize that your doing it.  For me I will break a watch down to its three basic components from a collecting standpoint...

1) Dial
2) The case
3) The movement

in most cases watches we like .... love ... obsess over have met one or more of the above criteria that we like . 


lets take for example a 1960s caliber 551 Piepan Connie 34mm case diameter not counting lugs or crown.

GREAT DIAL , most collectors love the dial !   The dial will sell this watch each and every time.  The case is ok but if the watch had a domed dial instead of a Pie pan, it is not the same watch period.  I do think anyone would debate that from a desirability standpont.   Next , the movement a 551 24 jewel Omega movement was KILLER, but quite common ....  Now thinking about the three areas I focus on ... I would consider a 1960s Pie Pan  Connie have a strong showing on one area  ( Dial) out of three .

Next

I recently purchased a Omega Marine from the 1930s ...

 1 ) The dial was original but very aged
 2) The case was steel , unique two part waterproof  case construction
3)  The movement 15j movement , I dont even remember the caliber !
That one hits two out of the three areas for me from an interest standpoint


How about a

Omega caliber 333 bumper sub seconds Seamaster chronometer

1)   The dial on my example is all monotone : Silvered dial with Steel / whitle gold markers and hands
2)   the 333 bumper movement is a deluxe executions chronometre bumper with Rg regulation system AKA Omega System
3)  The case  is a 36 mm steel classic first generation Seamaster  w beefy lugs and thick bezel !


This watch gets me excited on all three areas !   This is just a rough rule of thumb that I use when I look at a watch.  Everyone will have a difference set of criteria but each and every collector has them , some collectors just do not realize that they are doing that ....



So now lets look at the WDR ...
 
The dial ,  what can I say its stunning in my mind .   If you are fan of the RAF 53 "Thin Arrow", the WDR dial is the "Negative" of the RAF 53 dial.  Just for fun I took the stock Omega museum photo of the RAF 53 and then took a copy and inverted it  aka "make a negative"  .



I really like this dial and hands combo.  and the "white" dial version is even cooler.


The case was a "leftover" of the cases that Omega used for the RAF 53.    This case is something special as it was  special double hulled case construction with a movement ring and a heavy metal dial to create a faraday case to shield the movement from magnetic radiation.  The case was also screwback and waterproof at the time.  They Omega then "civilized" ( or decommissioned)  it by installing spring bars so you can fix a simple dress leather strap to the watch.  Actually come to think of it, the use of the white dial would also be part of the decommissioning  of the watch. 


The movement is a classic caliber 283 , modified at the factory with a swan neck assembly and balacne cock.  The movement was adjusted to chronometre specifications aka " Special regulation" The was planned to be rolled out with the caliber 284  but it was never put into main stream production.  The best I can tell you is that Omega possibly made no more then 1000 of this movement with swan neck 283 .

Looking back on this watch and the three criteria it hots heavy on all three areas ... 

so if you were looking for a Steel waterproof screwback anti-mag case with a chronometre grade 30 mm movement that has shock projection and last but not least a white dial your pretty hard press for this of another watch. 


This watch is very uncommon , I would even say rare ( and I do not mean how I like my steak cooked).   The WDR is a rare Omega that is never seen on the market.  I know some suggest its worth 5 to 6000 USD.    How can that be .?   What have you see a typical CK 2914 sell for ?  5k or 6 k ? so why would a small run of a prototype Railmasters sell for the same price ?   what does a RAF thin arrow 3 to 4 k ?    I just do not seeing it sell for approx the same price as the " common"  ( kind of a joke as there are very few...)  Omega Anti magnetic watches produced.

Would love to read your thoughts


Good Hunting

Hello everyone....


Back in 1999 I came across a odd looking Omega on ebay.   I was very interested in buying the watch.  I placed what I thought was a high bid for the watch.   The auction did not make its reserve price.  I  then proceeded to contact the seller.   We had a few back and forth emails but was not able to "close the deal".   i said to him please let me know if plan on selling in the future.   I would send an email every 6 months or so to check in.  Then he stopped returning my emails ( approx. 2001).

Well life goes on and so did my watch hunting.   i have found other interesting timepieces over the years.  Then one day in 2005 I was viewing MWR's PX and saw FS post titled " FS Omega while dial Railmaster ".  Most people did not even clicked on the post, as Omega in the 1960s a while dial railmaster automatic that is NOT in demand.   In comparison to the earlier manual wind Railmaster that was introduced in 1957 that had as special case construction that shielded the movement from magnetic interference.  

Upon opening of the post  the image that appeared was white dial Railmaster that was the same odd model of the one I "lost" back in 1999.   As fast as my mail program would open i sent a email to the seller that I would take it.  As soon as I sent it and email came in from a friend on the west coast saying he was going to buy the watch!  I gave him a call and asked when he sent his email to the seller and it was before me.  I thought oh well but at lest my friend will get it.  During the phone conversation he then said to me " I really cant buy it as cash is tight".  i took that as an opening for me to say " Hey, you know I sent him a email also but it was after yours and if you decide to pass on the watch please email the seller to let me buy it next.".   To make a long story short I was able to purchase the watch but had a problem getting it back home to the USA.   As the seller did not want to ship it outside of Germany.   I had the watch shipped to my close friend Steve Waddington.  Upon getting the watch steve told it arrived ok.  He asked me about shipping the watch to me I replied " How far away are you from Munich ?"  He asked why and I mentioned to him about watch fair that coming weekend.  Steve said no problem he will deliver it to another friend at the fair who will bring it back to the states ( I did not realize that it was a 3 plus hour trip one way for Steve).  Steve got the watch to Rick at the show and gave Steve a tour!  Rick had to show off my new watch to multiple dealers at the Munich fair.  I got an email from one of them., James Dowling  who is also a close friend.  James thought it was great and never saw another one like it.  I agreed.

A week later I finally received the box from Rick.  Upon opening the box and under close examination I realize this was the EXACT watch that I missed buying back in 1999.  This watch was originally posted for sale in Canada, sold to someone in Germany and then I was able to buy it.  I just started to laugh. 

The typical White dial Railmaster Automatic



There are three things that are uncommon to this watch.

1) The case ref 2777 was the case ref for the RAF 53 Pilot watch from Omega.  This reference was never offered in a civilian model ( until this watch came up !!).

2) The dial is a white version sans the Broadarrow of  the RAF 53 dial .  i have never seen this before. On top of that it was signed " Omega " " Railmaster". 

3) Close examination of the caliber 283 movement shows that it actually has a Swan neck regulator for micro adjustments.  I never came across any Omega documents that mention Omega used a swan neck regulator on any 30 mm family movement.  The only micro regulator on a 30 mm was the "Omega System " used on a 30 T2Rg ( that model did not have shock protection).

Now the quest begins.


I first posted the watch on the MWR.  I got a a lot of comments that included " redial" and "modified movement outside of the factory" .  I had the watch in hand and knew it was not a redial and the movement looked factory original to me.  I then sent an email to my friend John Deithem at Omega. 

His reply was the following...

*    the OMEGA mvt N° 14'158'9xx is of caliber 283 - special adjustment
for " chronometer rating " ( but not officially certified ! )
*    the case of ref. CK 2777 is the special construction , exclusively
delivered up to 1953 to the pilots of the RAF, and which has the inside
protection mumétal cover.
*    it looks like that we had too many cases in stock of the ref. CK
2777 and which were then in 1955 no longer required to be delivered to the
British Army... hence we had converted these " RAF " to another special
version, i.e. the ref. CK 2777 - with the original movement with "
chronometer special rating " of cal. 283.... but fitted with a dial marked "
Railmaster " and delivered to our Agents in Canada.
*    What is not possible to clear up, is why this " special " has been
made.
*    We anticipate that we had, at those days, a huge quantity of cases,
which were not introduced in the " International Collection " , hence not to
be used as a " normal " item of the Collection. The " Railmaster " version
was then made perhaps as only for the Canadian Railroad, with the white dial
and the hands looking different from the RAF watches ...
*    Therefore, the movement with a special regulator is a " novelty "
under the version of cal. 283, but indeed genuine ! 
*    For your information, your watch has been delivered ( strangely...)
under the ref. CK 2777 ( wonder why using the same ref. as for the RAF...! )
to Canada, on October 24, 1955.
*    The tool to make the cases " CK 2777 " have been destroyed in
1959...

    have a nice day

John's email was a good starting point.  But it was not a definitive answer .   Why have i not seen more examples of these watches.

I sent John another email....

Hi John
 
I just got an email from another collector, He recently bought a CK 2777-2
with a black dial that is signed Railmaster.  The caliber 283 also has the
swan neck regulator.  The watches serial number is 13 units away from my
White dial example that I bought a few years ago.
 
I have included your original research on my example. I would assume this
watch was also shipped to Canada at the same time in 1955.
 
Black dial same style as the RAF 53 ck 2777, but is signed Railmaster and
has removable strap bars.
Case ref: CK 2777-2
Movement: Caliber 283 with swan neck regulator, s/n 14,158,9xx
 
Any additional info on the above watch would be great.
 
John do you have any Idea how many caliber 283 with the "special" swan neck
regulator was produced?
( someone mentioned to me it was like 250 units, but I cant confirm that).
 
Do you know how many white dial Railmaster ck2777-2 were produced?
 
Do you know how many black dial Railmaster ck2777-2 were produced?
 
John, do you know if there are any White or black Railmaster dials availbe
in the spare parts at Omega and if so what are the part numbers?
 
Sorry for asking so many questions, but I know this is really an odd example
from Omega.  Its a very special watch, it is really the FIRST Railmaster
from Omega.
 
 I like to think if it this way, its a watch that is :
 
1) chronometre grade
2) Shock proof
3) Antimagnetic
4) White dialed ( my example is)
5) Steel cased.
6) Civil version of a exclusive military case!
7) Water resistant screwback case!
8) 38 mm in size!
 
This is really a very uncommon watch.  The black dial version that someone
bought and contacted me is the second one I have seen in all my years of
looking at Omegas.
 
Talk to you soon
 
Best regards
 
Bill

Well  as time marched on.  I came across a few other ck 2777-2 no other with a white dial but they all had the 283 with swan neck regulator.


They are all within a Very tight Serial number range, less then 1000.

14,158,9xx

According to the movement number we found some traces about the 3 watches ref. CK 2777 mentioned:

N° 14’158’9## - MOA -Production date : 31.10.1955 – Delivery date from factory : 18.04.1961 – UK




During this period of October 1955, several serials of 10 movements have been produced and most of them delivered to Canada but also to RAF/ UK for a few of them. Production sheets specify “Réglage Spécial” which means, “adjustment in four positions similar to chronometer standards”. But there is no mention of a fine adjustment regulator system.


I have talked with other 30mm “specialist, collectors”  they also agree with me that the swan neck appears to be factory original.

I have sent emails to Omega about the swan neck regulator and photos of the other Ck 2777-2.  But they can find no documentation to confirm that this was done at the factory.

Omega first denied it, I then sent close ups of the balance cock and regulator.  I asked them to take a close look at the workmanship.  For this to be done aftermarket or "Out side of Bienne".  The watchmaker who did it would have had to remove the balance cock.  Mill down the plate to remove the standard engraving for the regulator and then engrave the range box for the fine index regulator and then re-plate the part and then install the swan neck regulator.


I finally get another email from John who translated Daniel's research.  Please keep in mind this did not happen over night about 10 months past before I got the next email from Omega

Bill

Just for information, the following is a translation of the “news” just received from Daniel Anselmi – he is still on the work and we shall than have a final report by the end of January 2006.
In the meantime here is what he says:
 
“
Two of Bill Sohne’s watches of ref. CK 2777 and having the mvt N° 14’158’9xx und 14’158’9xx have been produced in October 1955 and according available photos, both have been fitted with the “ swan neck regulator”
 
However, the Museum watches having the same ref. CK 2777 and a mvt N° 12’804’201(Jan. 1953) , 12’999’581 ( June 1953) and 14’591’921 ( Sept. 1955) are not equipped with such regulator system, despite the fact that all are registered as “ RG “ but have no swan neck nor a RG regulator.
It seems, therefore, that the serial N° 14’158…is the field in which all such watches have been equipped with a “swan neck regulator”, probably only during a short period, since we have never seen such watch.
 
This is becoming more than interesting and Daniel has promised to continue his researches and we shall not fail to keep you informed about the development of this matter  - that will be therefore the first good news for the beginning of 2006.
 
Blessed Holidays
 
John

When I first read John email above I had a feeing that we were getting somewhere FAST !  Then a few days later I got another email...

Omega has CONFIRMED my 283 with swan neck is original from the factory.  They found only TWO pieces of documentation that shows the regulator and balance cock with the proper engravings.  Both of these drawings are dated June 29 1955.  They are drawing of the two parts:  balance bridge 284.1006 and the swan neck regulator 284.1356.   There is no other documentation at Bienne, no spare parts, no other indication that this watch was ever produced.  The part number are referenced to the next caliber they were designing caliber 284.   Also on the drawing of the balance bridge written in pencil   “Cancelled on December 14th 1957”.    A very small number of these 283 Swan neck movements were produced, aka caliber 283 Rg.



I think the email from Omega says it best ....

“  this type of product has certainly been manufactured during a short period of time which corresponds to the time of production of your watch. For any reason, this version has been cancelled soon, which explains why the watches same reference belonging to the Museum, produced at a different period of time, have a well known 283 calibre with standard regulator.

*Unfortunately we have presently no trace of destination or amount of movements produced in that version. “


The other question outstanding about the two 1955 Railmasters ( one black dial example and one white dial example).   The Railmaster wasn’t introduced until 1957, but both examples were sold in Jan of 1956 and produced in Oct of 1955 according to Omega records.   

According to Marco Richon :  ( Omega Museum, Bienne)

-         This white dial is original and produced in small quantity for specific order or purpose … (or)  ( have not seen another white dial example).

-         This white dial has been refurbished according to customer desire … (or)  ( No this is an original dial)

This watch is a prototype for the future “Railmaster” model.
 

Well since that email.  Marco Richon was writing a new Omega book  " A Journey Through Time".   He had asked me for hi res photos of my watch as he thought it might be interesting to have it in the book.  Well about a 15 months later a box showed up on my door step ( I purchased it ).  On page 221 Marco has a picture of two Railmasters one of them happens to be mine !





What you have just read transpired over a nine year period.   I just wanted to share the story with everyone here ! 

Happy Holidays and Happy New Year to all

Best regards

Bill Sohne

About the Omega Ref. 2777

The Omega reference 2777 is a notable example within the brand's early professional timekeeping instruments. This reference is recognized for its robust construction and specific design considerations, which set it apart from standard civilian models of its era. It represents a period when Omega was developing specialized watches for demanding environments, focusing on durability and legibility under various conditions. The design reflects a functional aesthetic, prioritizing utility over decorative elements.

This particular reference typically features a stainless steel case, designed for resilience. It houses a manual-winding movement, characteristic of watches from this period, known for its reliability and precision. The crystal is generally a robust material, chosen for its resistance to impact and clarity. The case dimensions are practical, providing a substantial presence on the wrist while maintaining wearability, consistent with the requirements of its intended users.

For collectors, the reference 2777 holds interest due to its historical context and its place in the evolution of Omega's tool watch offerings. It appeals to those who appreciate watches developed for specific operational purposes, showcasing the brand's engineering capabilities in that segment. Variants of this reference may exist, reflecting minor production changes or specific contractual requirements, adding to its collectibility and study.

it was news to the museum as well. there seem to be a few different versions over a short period. it started with fixed bars middle cases. but new backs were made. marked 2777 only ; absolutely centered inside the case back; no room to add - 1 or -2 to the 2777 stampings. backs without outside engravings first. movements taken from the surplus military 1953 version. no swan neck added. in the added picture the railmaster case is the top case; the military 1953 case is the lower one. next was the

Hi Bill, hi all, well, white elephants are rrrrrrrrrrrrrare as we all know... Bill, I already knew the story behind the WDR from your earlier posting and I watched the auction as many of us did (of course). Well, I must admit that I would have liked to buy the watch but not at any price. Speaking candidly I am not the guy for military watches and even these "derivatives" do not attract me so much that I would be ready to spend more than five figures... I have a near mint vintage Railmaster, a Sp

Hi Bill, sorry that I mentioned my valuation in numbers in the discussion about the white elephant... If you think tis violates the rules feel free to edit my post - there was no bad intention! I just wanted to give this numbers for comparison between the different "lines" of watches I collect as you did in your post... kind regards Erich
