Help identifying a cartier watch!

Hi all,

Recently came across this watch and was hoping someone might be able to help me identify its type/name.

It has a brown leather strap and red face. The back reads "18k gold, electroplated, water resistant" and "Cartier, Paris, 925".
The front reads "must de Cartier" and "quartz". I have not been able to find anything through searching, any help would be greatly appreciated.

Apologies I am no watch expert!

Many thanks
