Admitted Erich,

you clever man, Ben is officially baptized as Bernard.

And yes, in order to conduct tests for the Jump Second Program, a 30mm was heavily modified (as depicted in your post) and the synchrony of both the seconds indicators (each driven via different paths) was compared in an easy manner. As far as we know only ONE such a prototype was ever handbuilt (in the early forties) and I cannot imagine it ever ended up in the commercial circuit, but then again: you never can be sure...

For some reason the project was shelved at the time until many years later it came briefly on the market in a different form, but was quickly withdrawn again for reasons of reliability and technical service.

As Bill has explained already, since the 30mm SC-version possesses an indirect driven sweep-second it is ridiculously easy to attach an extra sub-second to the timepiece. Change the pinion for one with the longer shaft (as used in the sub-sec. versions), get yourself a little hand and dial from the mentioned version and there you go: two metal indicators rotating in 60".

But for what purpose? If you really want to, you could probably add a third (sweep sec.) indicator, or maybe even a fourth.. (kind of helicopter effect). In the early days it might have looked funny or even impressive - nowadays we're fully used to multiple indications on a dial, so the visual impact should be less dramatic.

So, peculiar? -Yes, for a collector. Very valuable? -I don't think so.

cheers, Ben.

Hi all. Not too long ago, when I asked about Ref 2545 39mm Omega cased by Central watch Case Co. Gator gave me the link about an Omega Ref 2545 which had Double Second Hands sold by Christie for 20,000 USD. ap.watchprosite.com Today, I received one like t...

That is a facinating...

if bizarre piece. I like that the hands are almost perfectly opposite each other, looks much nicer than some random offset between them congrats a

Guess the seconds differntal is like a GMT hour hand ? hhahahaha

HI I still find it hard to believe that Omega produce this at the factory. It would be a simple conversion for a standard Sweep sec model. You would need to find a sub second dial and a extra sub seconds hand. The pinion is there all you need to do is pla...

Yes interesting.

I wonder what the thought behind 2 second hands was? Like an "almost" chrono ("we ran out of development money to add pushers") ;-)

Hio, congrats...

i have not seen this model especially the extra long second hand, very interesting. congrats on this rare bird. thanks for sharing. stefan

I love it.

By: hoipolloi : July 8th, 2010-09:43

Hi all. I love it just because it is big and looks very unusual. At the first thought, maybe it did not come out of the manufacturer that way but it looks like only this model (2545, Cal 283) has this feature and somebody already spent quite a bit of mone...

Glad to have been of service...

BTW, when you have the watch cleaned, you should probably ask the watchmaker to synchronize the two seconds hands. Looks kind of funny out of synch like that. I took another look at the Christie's watch and it was aligned properly. You'd probably want to ...

Like this ?

By: hoipolloi : July 8th, 2010-14:34

The seller set them 30 seconds apart, now they are synchronized. Hi Erich. My second hand is creeping not jumping and I don't think it relates to the dead beat....

It is the same as with mine...

By: mac_omega : July 8th, 2010-23:09

Hoi, it is the same system as with my example and Bill and Ben both have explained how easy it is to create this peculiar feature. It has nothing to do with a prototype for the jump hour and I assume that at the auction it was the same system as with our ...

Here is mine!

By: mac_omega : July 8th, 2010-13:52

Hi all, I want to share pics of my example with 2 second hands as I bought it (as is) - and I have no suspect that the seller did some "special work" on it to enhance the value or desirability of the watch. He was no watch guy and was selling various ite...

I think that you are on to something here...

By: gatorcpa : July 8th, 2010-14:06

... as there are things in the auction description that do not make sense given that the cal. 372 is totally different than the 30mm movements. it wouldn't be the first time items were misstated in an auction description. Perhaps these were "special order...

Hi all, I'm new to this forum and came across it while I was looking for info about a Omega with double hands I bought some time ago. I hope to get some more info about this watch. This is the info I have: Omega Seamaster 30, around 1950, caseref14726-1 m...
