Tank Must Extra Large Automatic Stainless Steel / Silver / Bracelet

In Context

At 31 mm it is small by current standards, in the range most wristwatches occupied before cases began growing through the 1990s. At 8.4 mm thick it is about average for a modern wristwatch. The case back is closed, so the movement stays out of sight, and the mineral crystal sits between the two — harder to scratch than plexiglass, easier to chip than sapphire. Rated to 30 m, it is protected against rain and splashes and nothing beyond that.

The movement winds itself from the motion of your wrist. 40 hours of reserve carries it overnight, but not through a weekend in a drawer. At 28,800 vph the seconds hand advances 8 times a second.

WSTA0053 stands on its own in this catalogue — no other reference here shares its base number. It pairs a silver guilloche dial with a stainless steel case.

Self-winding movement with central seconds and date, introduced with the 2015 Cartier Clé collection.
