In Context

At 39 mm it sits just under the modern norm — the band that suits the widest spread of wrists. At 14.6 mm it is a tall case, and it will catch on a cuff. The case back is closed, so the movement stays out of sight, and the sapphire crystal will resist everything short of deliberate abuse. 60 m covers rain and hand-washing comfortably; it is not a watch to swim in.

The movement winds itself from the motion of your wrist. 44 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.

IW370631 stands on its own in this catalogue — no other reference here shares its base number. It pairs a black dial with a stainless steel case. It was a limited edition. Beyond the time it carries a chronograph.
