I've sent a message to the Geneva Observatory
Hi Dean,
As you mentioned in the end notes of your research, re-issues of Bulletin de Marche are available if requested. Therefore I sent them an inquiry about two Chronometre Royal watches.
Considering the "high production volume", I can understand that CR pocket watches were not sent in to Observatories for individual testing. If they were tested in groups, then I can imagine VC took that information and created their own certificates based on the Observatory results.
I've asked VC several times about whether or not copies of the timing results were available to watch owners but have not received a reply. Hopefully the Geneva Observatory will provide some information. If so, you'll be one of the first to know!
Best Regards, Dan
Vacheron & Constantin Observatory Chronometer
Vacheron & Constantin Observatory Chronometer: A Hard Working Watch Vacheron & Constantin, Genève, Chronometre No. 357355, case No. 229365. Completed in 1914. Very fine and rare 18K yellow gold keyless pocket chronometer with Guillaume balance. Awarded Bu...
Impressive research, Dean...
Thank you for writing and posting this well researched article. I especially appreciate the history of the Chronometer competitions from days past and the contrast with today's standards. I hope that the renewed competitions are embraced by the brands. I ...
AMAZING RESEARCH!
Hi Dean, This stuff is unbelievable and what I've been looking for! Thank you ever so much for this extremely informative post! I've only read it once. But will have to print it out and go over it very carefully to extract as much of that information and ...
VC and Chronometer Ratings
Thanks Dan Your comments are greatly appreciated, knowing how much of a Chronometre Royal fan you are. I'm looking forward to hearing about your research on the CR pocket watch chronometer ratings. An interesting fact that I haven't yet explored was the p...

Dan, I am surprised
On occasions I write to watch companies, some do not bother to reply. But at Vacheron, I always received a reply/replies Sometimes it is a good idea to initiate a communication with a phone call, then you get the person contact details you really ought to...
I think it may have gotten lost in translation?
Hi PoyFR, My communications with VC over the past couple of years have ranged from exceeding outstanding to poor. I made these types of inquiries to VC when I sent my watches back to Geneva for full restoration and Certificates of Authenticity. I discover...
An update
I've been talking to the VC Concierge in New York about what type of documentation came with 2 vintage Chronometre Royal watches (1908 pocket watch and 1955 wristwatch) that I have and if it was possible to obtain copies of any type of testing results, wh...
My vintage Chronometer Royal wristwatch from the 1950's
came with a COSC certificate, but nothing from the Observatory. This is not as rigorous as the Oberservatory tests, but still a nice to have, and unusual for a watch from that time period. Unfortnately I lost all my paperwork that came with the watch, and...
I like having everything accompanying the watch...
but not having the accessories doesn't take anything away from the intrinsic greatness of the watch. That vintage Chronometer Royal is still one of my keepers! Bill
are you sure the COSC certificate was not given at a later date as
COSC was created in 1973 wheras your watch is from the 50s!
Hmmm...
Now I've got to go find the photo I took of the certificate (which might only be on a computer I no longer have), since I don't have the certificate itself....Do you have access to the papers that accompanied the the early Chronometer Royal wristwatches? ...
Hi Bill, I recall seeing the timing results of your 1950s CR
in a post sometime in the past. I do not believe it came from COSC, it came from VC though I'm no longer sure who did the testing. This is also one of the reasons I was surprised that my 1950s CR does not appear to have been tested, or if it was tested in...
Timed When Serviced
I'd speculate that when Bill's watch was serviced or restored, it was also adjusted and a record was provided of the results.
Picture of a similar document?
Hi Bill, I found this picture of a VC Chronometre Royal "Bulletin de Marche", did your document look something like this? It is blank, which confuses me a little, so I'm not sure if it's authentic. If it is authentic, I don't understand why all CRs wouldn...
In-house Chronometer Certificates
Here is a completed certificate from V&C (image courtesy of Purists). Sorry for the bad focus but I had to enlarge it. I believe these documents were for watches tested in-house. Interesting to note that "especially good" was pre-printed on the blank form...
I sent an inquiry to the VC concierge
and we should know, definitively, what these certificates represented pretty soon. BR, Dan
Early COSC certificate
This early COSC certificate for a Rolex shows "Especially Good Results" also pre-printed on the form. The original Observatory Trials only assigned that distinction to movements that scored 80% of available points versus the passing grade of 66%....
Great post - loved reading it. The research behind it is evident and
I am so happy that someone has posted such an informed article on the Timing competitions and why they should return. I can only endorse your views by at least (and certainly no less) than 100 percent (or 1000 points). Great posting and thanks for doing s...
It's about TIME too...
Sorry for the pun, Andrew ;-) It has been frustrating for us gear-heads that, for the past several decades, issues of aesthetics and design overwhelmed the basic fundamentals of good timekeeping. I think a certain defeatism occurred following the quartz c...
Completely agree. I found it fascinating that the same
basic escapement that was winning Observatory trials in the 1940's (JLC Calibre 170) was again winning some 60 years later. Have a look at the escapement and bridge design - extraordinary. Vacheron were one of the clients of the 170 base ebauche who then ...
I would also chime in with...
the fact that many of the "high end" clients between 1870 and 1940 purchased their ebauches from JLC, and to see JLC take first and second place - with the points awarded, considering the above article - makes me stick my chest out proudly for the greatne...
Very informative article
Thanks Dean. I think the chronometry contest next year will be better attended and will also have a higher rate of success, as manufacturers now know what it entails and how the watches should be prepared. - SJX
Many thanks for your post. Only a 'few' do the real work
The information within your post is well prepared, informative and rich. We do not often realize the importance of true and long lasting works as it is often hidden behind materials and hypes. I welcome all those new tests about mechanical watches, they w...
Wow!
Very impressive watch. Vacheron Constantin's claim to fame (as well as Patek Philippe's claim to fame) and success in many parts of the world was directly related to the results of these Swiss Chronometer tests. It's really impressive to see all this info...
Reissued Observatory Bulletin
The Observatory Bulletin arrived yesterday, as reissued by the Geneva Observatory which is now part of the University of Geneva. After they confirmed by email that records of my particular movement existed, for a fee of CHF 200 they sent PDF copies of the...
Very nice, a great document to go with a VERY special watch!
Hi Dean, I think having that type of documentation really complements the watch. Congratulations. Have you timed the watch itself to see how it is running now? Any thoughts of having VC restore (if necessary) and trying to regulate it to the best of their...
Pocket Watch Revival
It is pretty impressive that you wear your pocket watch Dan Mine is just hanging in the display cabinet so I'm not too concerned about timing. At 57mm it's a mite big for daily use but I am very tempted to start wearing the X-thin once I buy a few shirts ...
I've been interested in pocket watches since I was a teenager
Hi Dean, The first PW I ever bought was through a catalog store, Service Merchandise, in the late 70s/early 80s. I've always been a little non-conformist The CR, being an antique, is not a watch I plan on using long-term in a daily manner. I just wanted t...
Fantastic information!
I'm researching a Royal Chronometer with a close serial number to yours, and this thread helped me immensely! It was sent to both Kew and Geneva Observatories, getting 1re Classe at both. I think there may be only other example like it. THANKS!
Post pictures!
Edit: its generally best to start a new thread about your watch rather than reopen an old post. You can always link back to this one.
