ilot's Watch Performance Chronograph Perpetual Calendar Digital Date-Month Ceratanium / Black / Bracelet

In Context

At 43 mm it is a large watch — well above this catalogue’s 40 mm median, and enough to dominate a narrow wrist. At 14.7 mm it is a tall case, and it will catch on a cuff. The case back is open, so the movement is visible without taking the watch apart, 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. 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.

IW3888-01 stands on its own in this catalogue — no other reference here shares its base number. It pairs a black matte dial with a ceramic, ceratanium case. Beyond the time it carries a chronograph and a perpetual calendar.

Mechanical chronograph movement, stopwatch function with hours, minutes and seconds, hour and minute counters combined in a totalizer at 12 o'clock, flyback function, small hacking seconds, perpetual calendar, large double-digit display for both the date and month, leap year display. Slightly different finish compared to 89801.
