Cartier Santos-Dumont Santos-Dumont Large

The case measures 43.5mm long and 31.4mm wide, and 7.3mm thick. Case material: Stainless steel (also gold and two-tone variants). Case size alone is a poor guide to how a watch wears; lug-to-lug length and how the bracelet drops off the case matter more, which is why we suggest trying one on before you commit.

Quartz (high-autonomy) or hand-wound depending on variant.

It is rated to 30 meters, about 98 feet. That covers rain and hand washing. It is not rated for swimming. One caution that applies to every watch on this page: a water resistance figure describes a new watch with fresh gaskets. On a piece that is years past its last service, treat the rating as unknown until it has been pressure tested.

Identified by model + size: Santos-Dumont, Large case. The slim, flat, strap-mounted Santos. Modern W-codes vary by metal, movement, and year.. Reading the reference is the fastest way to confirm that a watch is what the seller says it is, before you get anywhere near the movement.

Santos-Dumont, Large, steel, strap. Collector nicknames are not official Cartier names, but they are what people actually search for and what they are called across a showroom.
