Throwback Thursday – 1967: Girard-Perregaux Observatory Chronometer B-2153

Mar 22, 2018,00:49 AM
 

I am back!

smile

 

After a well needed family vacation in the sun I am back home.

 

This Thursday I would like to throw you back to the 1967…

We all know what happen that year at the Neuchatel Observatory in Switzerland.

Girard-Perregaux dominated and was awarded the larger part of all Chronometer certificates from the Neuchatel Observatory that year!

 

This box contains one of these watches…

Quite anonymous on the outside…


The Girard-Perregaux Observatory Chronometer B-2153.

The inside tells another story!

smile

High frequency Chronometer

Certified Observatory Chronometer

GP Winner of the first centenary award, astronomical observatory de Neuchatel, 1967

Self-winding

Water-resistant

Shock-resistant

Anti-magnetic

Guaranteed accuracy


Exactly how many of the Chronometers that actually stayed for the longer tests and became not only Chronometer but Observatory Chronometer is unclear.

This document from 1968 state:

662 watches were awarded Chronometer certificate.

73% of all Chronometer certificates that year.


Here is another document from 1968 stating the same 73%.


Now, my understanding is that only a partial of the 662 watches actually became Observatory Chronometer.

But how many I am not sure…

And unfortunately, the manufacture does not have any records left about this detail.


How many different references was equipped with Observatory Chronometer movements?

So far, I have observed this version, the reference B-2153 and the more famous reference 8795.

Would be interesting to know if there were any other reference using these movements, Calibre 32A.

 

At least, I have confirmation from external source that my watch was part of the 1967 batch of Observatory Chronometers and received a N-score of 10.01*.


 

Best

Blomman

 

* N-score is derived from:

Average deviation of daily rate

Temperature coefficient

Secondary temperature deviation

Rate resumption

Average deviation in position changes

What an entry to come back with!

 
 By: crown comfort : March 22nd, 2018-01:40
the Holy Grail of vintage GPs. Just amazing. Let's hope that one day we will find a good reliable source that can give affirmative details on the "Observatory Chronometers". And AHH that box... Best and glad to have you back my friend. CC

How to make an entrance....! ;)

 
 By: blomman Mr Blue : March 22nd, 2018-13:26
Indeed, let hope we one day can uncover all the details about the Observatory Chronometers! Best, my friend Blomman

That's a good question / observation, Frank

 
 By: crown comfort : May 31st, 2018-11:51
perhaps someone did not have the respect to stand behind his or her previous comments. But then, it's all about the original post by Blomman of a superb original watch and quality write-up.

You are not just back but you are b-a-a-c-k!!!

 
 By: Ares501 - Mr Green : March 22nd, 2018-02:14
Amazing full set of one of cult and very very rare vintage pieces from G-P....what I gathered only 40 to max 60 movements got Observatory certificate and their movement numbers can be found in Neuchatel Observatory records! See the color of the inside of ... 

You mean the beige part? 😁😉

Indeed, not easy to find! :) [nt]

 
 By: blomman Mr Blue : March 22nd, 2018-13:29

I agree the result is achieving the status of Chronometer

 
 By: piccolochimico (aka dsgalaxy1) : March 22nd, 2018-23:23
Besides that, the dial was changed with that statement Observatory Chronometer. GP did it and filled that official report 😎

That’s what I meant to say

 
 By: piccolochimico (aka dsgalaxy1) : March 23rd, 2018-02:11
GP has aslo manufactured a new dial to fit your watch with the Observatory Chronometer sign. I know vintage purists love patina dials, but for me a rusty dial is just... rusty, or damaged 😜 I appreciate more a perfectly restored watch, but that is me

I guess.....

 
 By: Baron - Mr Red : March 23rd, 2018-03:31

A philosophy of how to collect vintage

 
 By: Baron - Mr Red : March 23rd, 2018-04:59
Some have no interest in whether a vintage watch is authentic and original whilst to others it matters a lot. That isn't just vintage Rolex, it applies across the whole vintage genre...Omega, JLC, Patek whatever. The philosophy refers to how one views col...

Pardon, but where did i mention you or any other watch collectors?

 
 By: piccolochimico (aka dsgalaxy1) : March 23rd, 2018-05:18
I used the word RUSTY because that's how I see some vintage dials. I have long discussions with vintage friends But that's me, no offense intended 🌝 I agree there are 2 main groups of vintage collectors, those who let the watch untouched and unserviced, t...  

Sorry just to clarify your point if GP wrote it then it must be ok?

 
 By: Ares501 - Mr Green : March 23rd, 2018-06:47
Is that your take on this piccolo? Cheers D

Yes.

 
 By: piccolochimico (aka dsgalaxy1) : March 23rd, 2018-07:22
I never take anything for granted. in a rating system chart, I'd put GP at the top of it To whom shall I believe? 🤔

Kind of response that Phytia would give :)

 
 By: Ares501 - Mr Green : March 23rd, 2018-07:50
Yes you trust GP or Yes you never take anything for granted. To whom shall you believe? To your own eyes....yes I understand I have naturalistic point of view...but on other hand do you have any piece of evidence to trust GP? Cheers D

Indeed, a original one in bad condition is not more than a few hunderd dollars. A repainted is even less...

 
 By: blomman Mr Blue : March 23rd, 2018-05:08
But that is only interesting if you are about to sell your watch. If only to keep, wear and enjoy your watch... Then of course you should do whatever you like best!

ahhhh.... i realise now that i stepped on a mine.....

 
 By: Baron - Mr Red : March 23rd, 2018-05:28
I see now....this is a watch that you bought in a ruined state and you had it fully refurbished so that it "looked" like it was back to an original state. And you were not looking to see its value increase....right......... Good idea Ken......good idea no... 

Guys, there is no blame game here!

 
 By: blomman Mr Blue : March 23rd, 2018-10:21
Ken, you asked for opinion about your watch. You got opinions, some you like, some you like less. No point in starting any blame or personal attack here. It doesn't matter if your watch is a Observatory Chronometer or not... Since your watch is not in ori... 

You sold the watch and had to refund it? OK, now I understand why you are trying to find someone to blame

 
 By: blomman Mr Blue : March 24th, 2018-02:34
Ken, again. You asked for opinion about your watch. You received different opinions. Some inline with you, some not. But that you already knew you would. It was the same back when you serviced the watch you received different opinions about how to go forw... 

The truth is that vintage watches are never straight forward, black or white

 
 By: blomman Mr Blue : March 24th, 2018-13:00
It’s not like modern watches where you can walk in to a store and just buy whatever you read about in a press release. I gave you my view of what is an Observatory Chronometer, more that that I can’t do without more information about your specific watch. ... 

Ken.....

 
 By: Baron - Mr Red : March 24th, 2018-23:37
.....i assume that you are implying that you lashed out at me. Let me be very clear here.....my comment on this was the following: The “observatory” was only applied during the overhaul? They changed the dial during an overhaul? Is that correct? If so, I ... 

I've been following this thread and wondering . . .

 
 By: Dr No : March 25th, 2018-00:32
. . . if Ken's comment on the dial as initially received, before it was sent to G-P for restoration, has been overlooked. The dial wasn't correct when G-P received it, being smaller than it should have been. If that is the case, then there isn't an issue ... 

Good to see you here in the GP forum, Art!

 
 By: blomman Mr Blue : March 25th, 2018-12:10
You do not often come and visit. Sorry for the circumstances. As for your question. Not overlooked, just not commented on since the main question has been, is this watch an Observatory Chronometer? But since you ask, let’s reflect on “the dial is too smal...  

The implication, then, is that the dial currently in the watch . . .

 
 By: Dr No : March 25th, 2018-12:52
. . . is the same as the one installed before it was sent to G-P for restoration? And that its differing appearance now (other than the script) at the junction between the periphery and the case is due to a corrected crystal/tension ring installation? If ... 

Dear Art, I understand you have been asked…

 
 By: blomman Mr Blue : March 26th, 2018-01:39
But before you imply who made or what has gone wrong here. Please consider, here in the forum we only have the version from someone that gets very upset of those who do not agree with him. Someone that even if advised differently, went along and changed h...  

Agreed, Blomman - any vintage that doesn't retain its original equipment . . .

 
 By: Dr No : March 28th, 2018-01:31
. . . isn't collectible, in my humble opinion. That's why I never send my Omegas to Bienne for restoration - there are simply too many instances of watches sent there with specific instructions of measures not to be taken which are then ignored. That said...

Forgive and forget…

 
 By: blomman Mr Blue : March 25th, 2018-12:11
You brought up old things that should have been water under the bridge by now. I even asked you if you really wanted to take that discussion here in the GP forum, I even asked you to think twice before replying. In your reply you even wrote “I stop here”.... 

Your letter confirm that your watch is a Chronometer but do not say anything about Observatory Chronometer

 
 By: blomman Mr Blue : March 23rd, 2018-01:08
To my understanding, all Chronometers has been tested by a Observatory, in this case the Neuchatel Observatory. BUT , that do not make all of them Observatory Chronometers. After the normal Chronometer test, some of the watches stayed for a longer Observa... 

Thanks, but...

 
 By: KIH : March 23rd, 2018-01:38

I will not spekulate in what been said...

 
 By: blomman Mr Blue : March 23rd, 2018-01:46
But your letter only confirm Chronometer. As for how well manufacture's are at recreate dials, I (and I think others here as well) can confirm that what you get back after service are not always the correct outcome.

Hi Ken!

 
 By: Ares501 - Mr Green : March 23rd, 2018-03:37
I've been reading through this thread cos I care about G-P and love it. Also I remember posts from years back about this piece of yours that I see you still love. Now please allow me my take on this "case"...but first I will cite Melvyn ..."You are correc...

Have you tried getting documentation from the Observatory; or FHH?

The Neuchatel Observatory records show that my watch received the N-score of 10.01

I still have mine... Had to use a spare 32A as a parts donor for my 32A with the full set of b&p.. Sorry to chime in late, but if Ken's watch is listed on this www.observatory.watch database, it's an Observatory chronometer, as the URL lists ...

As you know, there is always a story to tell...! Best Blomman

what is a Observatory Chronometer worth?

 
 By: ivremore : July 27th, 2018-17:55
Given the relative rarity, I have not seen any values except for one that sold for auction 3-4 years ago in Germany for $1400..

Welcome here, ivremore!

 
 By: blomman Mr Blue : August 1st, 2018-11:15
Well, we - or at least I try to avoid discuss prices here in the forum... But I can tell you that the price for a original Observatory Chronometer in good condition has gone quite a bit up north last few years... Best Blomman

thanks!

 
 By: ivremore : August 2nd, 2018-07:49
I do wonder where all these Observatory chronometers have gone over the years. According to the database, there are 702 for the years 1966/67, 40 the first, then 662 the second yet as best as I can tell, maybe ten have appeared over the last 10 years that... 

Just to clarify,

 
 By: blomman Mr Blue : August 8th, 2018-11:05
Yes, 662 Chronometers in 1967. All Chronometers were certified by the observatory, but not all Chronometer had Observatory Chronometer on the dial. Best Blomman

this is where it gets murky

 
 By: ivremore : August 8th, 2018-13:45
Hi Blonman. The database shows 702 entries for GP chronometers. I know of GP chronometers with serial numbers that do not appear in the database. Is there any known serial number for a GP Chronometer that is in the database but does not have the Observato... 

No stright answer...

 
 By: blomman Mr Blue : August 10th, 2018-03:27
But we know: - All Chronometer must have been certified by a observatory for being allowed the "Chronometer" on the dial. - All Chronometer did not have "Observatory Chronometer" on the dial. Most have only "Chronometer HF". ... Best Blomman

so.....

 
 By: Baron - Mr Red : August 14th, 2018-06:22
.......by definition, GP were making a distinction between a Chronometer HF and one with Observatory Chronometer.... a distinction that should not be lost or blurred

Yes. [nt]

 
 By: blomman Mr Blue : August 17th, 2018-10:03

Looking at the database website, it seems to imply that it only contains the Observatory Chronometers

 
 By: ivremore : August 15th, 2018-13:18
Here is text: "The database contains all mechanical timepieces ("chronomètres-mécaniques") submitted under the wristwatch category ("chronomètres-bracelet") to the observatory competition in Neuchatel, Switzerland ("Le Concours chronométrique de l`Observa... 

As said...

 
 By: blomman Mr Blue : August 17th, 2018-10:08
All Chronometers (regardless of brand) had to be tested and approved by a Observatory to be allowed to bear the "Chronometer" on the dial. That include all Chronometer HF. BUT, only a part of all Chronometer HF did have the Observatory Chronometer dial.

I am not sure this is strictly true

 
 By: ivremore : August 17th, 2018-10:33
According to this (#Observatory_trials_and_standards_before_1973), movements that passed the testing by the Bureaux officiels de contrôle de la marche des montres (B.O.s), the precursor to COSC(?), would be certified as chronometers (just not observatory ... 

I find it very strage and disturbing that someone who claims to be the most honest man deletes and edits posts.

 
 By: blomman Mr Blue : October 29th, 2018-10:29
Not only his own but my posts as well. From now on, KIH - please do not edit any more of my posts! Especially not without informing me! I find that behaviour very questionable. Blomman
