Pilot's Watch Double Chronograph

In Context

At 46 mm it is a large watch — well above this catalogue’s 40 mm median, and enough to dominate a narrow 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. 44 hours of reserve carries it overnight, but not through a weekend in a drawer. At 21,600 vph the seconds hand advances 6 times a second, the slower and more audible rate of an older design.

IW3778-01 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. Beyond the time it carries a chronograph.

Rattrapante / Split Seconds movement with day and date window.
