Calibre 1072 in Non-Date Case?

Does such a creature exist?  Recently I saw a non-date automatic VC ref. 6394-2 and was surprised to see that the movement was marked K 1072.  Is this an illegitimate marriage?

Adding to my confusion, The Watch Quote had this to say in Sept. of 2007, on the release of the newest Chronometre Royal:

This concern for chronometric precision is intimately bound up with the history of the Chronomètre Royal watch. It was perpetuated with the emergence of the first self-winding movements – Calibres 1072 and 1072Q with date – that were to equip the Chronomètre Royal from 1962 onwards.

it is possible, the 1072 came in two vatiations: 1072Q being the
01/08/2008 - 22:51

the version with date (Q as in Quantième = date in French). I agree hpwever that I have very rarely seen the 1072 used in its non date version.

The Ref 6562 hereblow uses the non date version

Seems like a rarity...or is that oddity?

Thanks Alex.  That's amazing...I must have looked at a dozen 1072 watches at Antiquorum and all had the date feature.  So this brings to mind a question of rarity as the watch I was examining was the /1 version with gyromax balance!

Do you know if VC has any production numbers for their "modern" wristwatch movements and would that be available to us?

rather an oddity because I belive that the vast majority of models

with cal 1072 had the date!

VC certainly has the production numbers but will probably not disclose them...its the secretive Swiss thing

Alex, how does a "non-date" K1072...

differ from the K1071?

I'll check. I always thought that the big difference was the adding of
01/09/2008 - 11:25

date to cal 1071 making it 1072 but obviously I was wrong...

I'm not sure the pictured watch contains a 1072 movement

If that photograph comes from an Antiquorum catalogue, Antiquorum describes it as a caliber 1072/1 with a micrometer regulator. That is obviously contradictory, as the 1072/1 used a Gyromax regulation system, so I think it (and also the style and date of the watch) casts doubt on whether the 1072 part of the number was correct.

This may be somewhat moot in light of the additional information you have unearthed. Perhaps more importantly, it appears that it Tick-Talk wants a dateless 1072, he can get the identical movement by buying a 1071, which gives him a lot more choices. However, if he wants a dateless version using a Gyromax balance, I think he is out of luck.

I stand corrected, you are right. Thanks for the heads up (nt)

In this case, I personally believe that...
01/09/2008 - 13:15

the bridge may have been swapped. I believe that VC (or V&C) has had a very systematic means to designate its automatic movements for a very long time.

K1071 => Swan Neck w/o Date

K1072 => Swan Neck w/ Date

K1071/1 => Gyromax w/o Date

K1072/1 => Gyromax w/ Date


I need an's VC's official reply on the question
01/09/2008 - 15:05

the difference between calibers 1071 and 1072 is the fact that the latter has a date function. However, the caliber 1071 was made for only 5 years (1958-1963) and subsequently derived into caliber 1072 and models with caliber 1072 without date are using cal 1071 renamed cal 1072.

However models with caliber 1071 were produced from 1958 til circa 1972, which means that basically during that time (1958-1972) VC had non date models using both calibers 1071 and 1072.

To make a long story short cal 1072 without date is a caliber 1071 which was renamed.

Great question Tick-Talk and Tony, I learn something new each day!

Thanks Alex...

and while it certainly is odd that V&C chose that approach, it occurs to me that if I happen to find myself in a bar with a pompous watch collector who fashions himself a vintage V&C expert, I'll probably be able to make a couple of dollars with that information!


On a more serious note, I am impressed by V&C's honesty and willingness to answer these sort of obscure questions in a timely manner.

We all appreciate your help as well, Alex.

Best regards,

Tony C.

This stuff is gold!

Exactly right Tony...this kind of minutiae is gold to VC enthusiasts and the Hour Lounge is the only place to get it!

Give me one more...

aspirin too, Alex! Thank you very much for another unusal fact explained by VC. There're always new things to learn from VC. This kind of renaming the movement could happen, particularly during the model transition period. A similar thing (with regard to an unmatch dial model number, movement model number & caseback model number) can also be found in the GS second model as well.

Regards, Joe


P.S. This kind of the unusal facts may to some extent pave the way for those watches having a swapped bridge.

Include pics of front, back.  Also views of the movement and markings on the inside of the case back if you can.  Lastly, please share the story of your interest in the watch yes.
