I purchased this watch at the Cartier 5th Avenue NYC store in the mid- 1970s. I know it is gold vermeil and is stamped on the back
"PLAQUE ORO 20 M" or "PLAQUE OR 020 M". Does anyone know what it means? Also, it does not say "MUST" on the face like most of the other 70s era tanks I've seen. Is that of any significance? Thanks for your insight.

I am not an expert on Cartier watches, but I used to have a lovely one, and I did some research about 10 years ago...
I remember these Cartier tank watches very well. They were all the rage in the mid-70s. The "Must de Cartier" vermeil watches were introduced in 1976 (according to Wikipedia) but maybe yours is earlier.
Sorry, I have no idea what the Plaque Oro 20M means. It must be something about the composite of gold to silver, but I don't really know.
I own a similar Cartier vermeil tank watch; it my favorite style of all times. I once owned a Cartier 14K gold tank watch but alas it was stolen. The 'Plaque Or G 20M' indicates that the case is solid silver with a 20 micron plating of gold. the concept of "Les Must de Cartier" means something one simply must have! Must de Cartier' was included on tank faces starting in 1972.
Wow, thanks David! That's a lot of good info!
