Pilot’s Watch Timezoner Chronograph 80 Years Flight to New York

In Context

At 44 mm it is a large watch — well above this catalogue’s 40 mm median, and enough to dominate a narrow wrist. At 16.8 mm it is very tall, and sits high off the wrist. 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. 68 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.

IW3950-03 is one of 2 executions of the IW3950 base reference. Underneath they are the same watch; what separates this one is a brown dial and a stainless steel case. It was a limited edition. Introduced in 2019. Beyond the time it carries a chronograph.

Flyback chronograph with combined minute/hour totalizer. Additional 24h hand working in cooperation with the rotating bezel to show the time in selected timezones.
