Vintage VC Ref 7937 questions

Hi all experts: Just acquired this Vintage Vacheron & Constantin watch. Upon opening the case back i found on the back of the case shows model number (i guess?) of 7397. Anyone here knows about this watch? i couldn't really find too much information on this. I want to know the following: 1) is the crown original? looks too plain for a original crown. 2) what year is this watch? 3) how to polish the crystal (or is it even crystal ) or case, or if i should just keep it as it? 4) it runs... should i bring it to service? should i bring back to AD for servicing? would that cost more that the watch value? 5) while we are at it.. the watch value, the strap is not original, the rest seems to look legit. 6) the watch where it holds the watch strap is very tight (the band can't move), is there a special strap or strap pin that i should use? Thanks all !

  1. is the crown original? looks too plain for a original crown.  Impossible to tell with those pictures, here’s a ref 7937 in NOS conditions (picture taken at the AD store) for your comparison
  2. 2) what year is this watch?  Need case and movement serial numbers, an extract from VC would help. Given its escapement configuration, it should be first of the seventies; just a guess
  3. 3) how to polish the crystal (or is it even crystal ) or case, or if i should just keep it as it? It’s possible to polish plexy, so if the beauty of the dial is beclouded by the glass, why not?
  4. 4) it runs... should i bring it to service? should i bring back to AD for servicing? would that cost more that the watch value?  It depends last time it was serviced, any info about its history would help. Any watchmaker is able to check its amplitude, it’s the most important thing  you can do to have a clue, then a close inspection to lubricants’ conditions will tell. I don’t know how much you spent but that’s not important, best thing to do is ask to an AD for an estimate, both, for price and time to service the watch
  5. 5) while we are at it.. the watch value, the strap is not original, the rest seems to look legit. I just can say it looks original in any part, the dial is very nice and well kept, that's a point of strenght of your watch - imho
  6. 6) the watch where it holds the watch strap is very tight (the band can't move), is there a special strap or strap pin that i should use? Probably the former owner used a strap with a wider length at the lugs, it works but that’s the inconvenient you get. An original strap and correctly sized, will solve the problem

 

Hope this helps :-)

You're definitely welcome :-)

Remember to protect the case while applying any abrasive paste, anyway, a watchmaker can do the job professionally.

Hi 

I was just wondering if the AD is in Toronto. I have an OS that needs attention and will be in TO next month.

I'm sure it was just a mis-type, but the correct reference number needs to be somewhere in this thread for when our Search function returns smiley.  I too am thrilled to see your lovely watch, take good care of it!

A steel case and cal 1072/1 is a rare combination.  The movement is well known to be of excellent quality.  Congrats!  Best Regards, Dan

Hi Woody, I can feel the excitement in your posts. Vacheron and other high end watches have that really special effect. I returned a 50's Vacheron to HQ Switzerland around 18 months ago via the boutique in London. The estimate took around 4 weeks with no commitment. It was a fair amount of money relative to the purchase price but equally a fair amount of work by some of the best in the business. The estimate said 12 months to repair and almost 12 months to the day I collected it. Worth every single penny. The finish was impeccable it now proudly sits amongst the finest in my collection.

Hi Cliffo, would love to see your 1950s vintage VC

Hi Dan, Do you know if this cal has a over winding prevention? My watch stopped today and i wind it a little daily, i suspect that i didnt wind enough but worry to over wind. Thanks!
Hi Woody, the movement is an automatic winding design

I have 2 watches with this movement, but I don't know what its exact Power Reserve is.  I've never had a problem with it lasting when I wear it.

I do not know for sure if it has over-winding protection, but I believe it does.  Automatic winding watches usually do not stop when you use the crown to wind it manually.

i usually wind it up about 15-20 turns, and put it on my wrist.  The initial power from manually winding it and then having it do some of the winding by itself (taking the energy from motion of your wrist moving throughout the day)...it lasts me as long as I'm wearing it and at least 24 (if not 48) hours when I put it down for a longer period.

If your watch stops after winding it up even more, I would take it in to an expert watchmaker for a check (preferably a VC watchmaker).  In fact, I always have my vintage VCs serviced by VC before I use them.  That way I know they are in top condition and I am not damaging it even more if I bought it in "less than good" condition.

BR, Dan

Thanks for your info Dan. My watch works great when i am wearing it but if i leave it unworn for a day it would stop. I will save up and soon send the watch to VC!
