Aquatimer Split Minute Chronograph Rubber

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 16.3 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. 120 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. 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.

IW3723-04 is one of 2 executions of the IW3723 base reference. Underneath they are the same watch; what separates this one is a black dial and a titanium case. Beyond the time it carries a chronograph.

Chronograph with additional minute hand for split minute function as used in the Aquatimer Split Seconds.
