In Context
At 40 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 11 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. 50 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 28,800 vph the seconds hand advances 8 times a second.
16570-0002 is one of 4 executions of the 16570 base reference. Underneath they are the same watch; what separates this one is a black dial and a stainless steel case.
