chronomètre calibers from VC

Good morning,

Could you let me know if caliber P 453 is considered as a chronomètre caliber ?

Which are the calibers that are chronomètee "certified" or "considered as" ? (apart from Chronomètre Royal)

Many thanks,


I know one...

Cal.1311 (old Overseas non-chrono ref: 42042/423A GP base) is a chronometer.



There is also cal 1206 RDT found in the Malte Dual Time Regulator and

caliber 1204 housed in the Malte Big Date which are both certified chronometer movements.

BTW the caliber 453 as beautiful as it is it is not

chronometer grade (the official Chronometer certification dates from 1973)

geneva seal doesn't have timing criteria, does it?

I never remember whether geneval seal has any timing criteria.... I think it doesn't though.

In any event, since COSC dates from 1973, what did "chronometer" refer to before that? ("chronometre" royal for example).

Did they have their own criteria?

This brings the question of the "tested in 5 positions": to what criteria of timing did they test the watches?


The geneva seal criteria is based only on finish. Regarding

chronometers I guess I was not detailed enough. The principle of chronometers and chronometer grade was set out in the end of the 19th century where watches had to undergo certain rating tests as well as to heat and cold with an average deviation which should have remained within cerain predefined limits. The term chronometer was used for watches which underwent such tests and which were precision timekeepers.

Since 1973 to be able to use the word chronometer a watch has to have obtained certification from the COSC.

I gave a partly wrong info on the cal 453..mea culpa

Here is full information on VC's chronometer calibers (other than in Chronometre Royal models)

Reseach shows that almost all chronometer movements used by VC were in Chronometre Royal models. 2 calibers were used - cal 453 - cal 1072 (automatic with and without date) used in the 70s but exclusively for the Chronometre Royal It is only from 1996 that Vacheron started using chronometer calibres in watches other than the Chronometre Royal in a regular manner: - Overseas with calibre 1310 (GP base) (1996-2004)

- Cal 1320 (quartz) also from GP and used in the mens Overseas (1996-2004 representing less than 10% of the Overseas production of the time)

- cal 1204 based on Piguet ebauche and used in the Malte Big Date (2000-2005) - cal 1206 which is also based on a Piguet ebauche (1150) but which Vacheron modified for 2 different models 

  • Malte Tonneau Day/Date (ref 42008): this model was a chronometer from its date of launch in 2001 til 2003 where the dial was reworked (applied numerals instead of painted numerals) where the chronometer certification was abandoned
  • The Malte Dual Time regulator launched in 2000 

The goal in the long run, once production of VC’s inhouse calibres 2450/2460 can be upped is to replace calibre 1260 by VC inhouse chronometer certified calibers

I thought that also cal 1007 and 1008 BS were used in Chronometre Royal.

Why did not you talk about them?

Can you also, Alex, send pics for the 2 others, 453 and 1072?

Thank you and cheers, Anka

The question was
05/10/2007 - 16:40

on chronometer movements used in watches other than Chronometre Royal that is why I did not talk about the calibers you refer to which were the two manual winds used in the Chrnometre Royal models (for more discussions and scans check the Recommended Threads section re Cal 1008)

I'll see if I can find a scan of call 1072 but meanwhile here is one of 453:

the reason I raised the original question, was to check the statement of an ebay seller saying its VC with cal. 453 , was a chronometer version.



It was an interesting subject to raise. You did well and we learn

Hello Alex

here is a scan of the cal 1072

OK Alex; after all the infos exchanged among us, I forgot the original question.

Anyway, this was a good course to learn more, and thanks for the pics.


call me stupid
05/10/2007 - 20:34

but I still don't fully get it. So you are saying that the caliver 453 and 1072 are chronometer calibers? But you also say that almost all chronometer movements were used in the chronometre royal models...

So they used those movements in Chronometre Royal models.

So anyway, here's my question: was the caliber 453 a chronomter caliber or not, in the chronometre royal models, or in any model? :-)

Thanks. I'm a bit slow today...

I'm not being clear I guess. Cal 1072 is a chronometer caliber used
05/10/2007 - 20:36

only in the Chronometre Royal models. Cal 453 is a chronometer caliber but not used in Chronometre Royal models

Many thanks!! this is great info on pre COSC days for VC. (nt)

Also cal 2460 SCC found in the Chronometre Royal 1907

There is book "Augenweide Armbanduhr Vacheron Constantin" by Anton Kreuzer from 1992.

It's written in German, but it has nearly all vintage calibers commentade.

The one's that got "Chronometerqualität", that's chronometerquality,

according this book are calibers :










Fantastic Doc! This thread is definately going to the Recommended

After doing a search on chronometer calibers, I found this older thread.  Just to complete the information it should be noted that all ref. 6782 "Thunderbird" automatics (approx. 100 pieces according to Antiquorum) featured the cal. 1072/1 "chronometer grade" movement.Click here for Thunderbird thread
