Vacheron Constantin

I have a vintage Vacheron Constantin # 31451
There also appears to be a hand engraved number with a date inside like a jeweler added it. it says something like 113401 and a date.
Is there a catalog I can research more about this model?

There can be three numbers engraved at various places on a Vacheron Constantin watch. They are the case serial number, the movement serial number, and the model's reference number (referring to case style). From your post I cannot tell for certain which ones you are referring to. If you have photos of your watch you and can post them here that would be helpful for us in trying to help you.

In general when researching a VC watch it is best to have both the case and movement serial numbers.

Best regards,

Usually one will find a 6 digit case number, and I am confused by there being only five digits.

Thanks,

Here are some pics. The watch needs to be cleaned but maybe you can give me some advice on the numbers? Thanks for taking the time.

The engranvings on the inside of the case back don't seem right to me. I have asked someone at VC to look at this thread and I will report his findings.

VC sent the dial and movement to the US where they were cased by the agent.

Troy,

The movement, although not clearly visible, will yield alot of info as to its age and calibre.  The movement looks like it is in good shape.  You would have to obtain a few good scans of the movement and its serial number to determine age.

As to the case it looks interesting, with what appears to be a reeded bezel and a curvex back.  This type of watch was popular in the 1940's.  As Alex and Bill mentioned, the case was looks like it was manufactured in the US, particularly using 14k gold.  Apparently, theere was a duty issue on 18k European made watches so many watches of the era were cased in the US.  LeCoultre was one of the most prominent watch makers at the time (also was affiliated with Vacheron & Constantin at the time) that cased in the US.

I suspect when the movement is properly cleaned and adjusted and the case and dial restored to your wishes, you would have a very attractive watch, unique in appearance with a fine movement keeping very accurate time.  Personal enjoyment is the key here as value to the persnickety collector would be remote.

Best wishes,

Robert
