Pasha de Cartier

A round Cartier sports watch with a crown guard hanging from a small chain.
The Pasha came out in 1985 and took up a name that, according to the brand's story, belonged to a waterproof watch made for a pasha in the 1930s. The round shape was new for Cartier, which had mostly made rectangular watches.
Materials: Gold or steel, sapphire crystal; self-winding movement
Manufacture: Made in Switzerland; the crown guard screws down.
