Santos 100 41.3 Carbon

In Context

At 41.3 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 10.34 mm thick it is about average for a modern wristwatch. The case back is closed, so the movement stays out of sight, and the sapphire crystal will resist everything short of deliberate abuse. 100 m is genuine swimming resistance — more than the shape of this watch suggests it would need.

The movement winds itself from the motion of your wrist. 42 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.

WSSA0006 stands on its own in this catalogue — no other reference here shares its base number. It pairs a black matte dial with a stainless steel case.

Self-winding movement with central seconds, available both with and without date.
