Any idea which Vacheron is this?

Any idea which Vacheron is this?

The information I know about this watch is minimal... Here is what I know anyway:
- Made of 18k gold all-around
- Sapphired Crystal
- Mechanical movement
- Purchased in 1980.
- Ultra-slim case

This watch belongs to a friend and I figured he doesn't know its value. I am therefore here to ask about any information anyone has about this watch, and what market value it has.
Maybe that'll make him appreciate watches...wink

ask a watchmaker to remove the back of the case.  Then you can take pictures (or at least read the information) on the movement and inside of the case back.  What you want are: 1. the movement's serial number 2. the case's serial number 3. the case's ref. # (4 digits) From just the picture you provided, I would guess that the watch has an automatic movement, cal. 1121.  Cal. 1120 is the base movement and at that time was the thinnest automatic movement in the world (I think it is still the thinnest automatic movement with a full rotor).  Cal. 1121 added the guichet date and with it, a very little bit added thickness. We don't talk about current valuations of specific watches on this forum, so if anybody would like to provide specific information - please do so through PM.  As always, Loungers usually recommend taking the watch to one of the large auction houses for valuation, i.e. Antiquorum, Christie's, Sotheby's.

Thanks for the comprehensive information about the watch. It's very interesting to know that the automatic movement is one of the thinnest in the world. We should go to one of the large auction houses soon and I'm thinking of buying it off him. P.S.: The valuation was only his main concern but I wanted to know more information about the watch. He wasn't too sure it will be worth more than the gold on it, but I insisted it'll be worth more as being a Vacheron.
