Big Pilot's Watch Perpetual Calendar Top Gun Woodland

In Context

At 46.5 mm it is a large watch — well above this catalogue’s 40 mm median, and enough to dominate a narrow wrist. At 15.9 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. 168 hours of reserve puts it well past a weekend — several days off the wrist and it is still going. At 28,800 vph the seconds hand advances 8 times a second.

IW5031-01 stands on its own in this catalogue — no other reference here shares its base number. It pairs a red sunburst dial with a ceramic, ceratanium case. Beyond the time it carries a perpetual calendar.
