Speedmaster Split-Seconds Stainless Steel / Blue / Bracelet

In Context

At 43.3 mm it is a large watch — well above this catalogue’s 40 mm median, and enough to dominate a narrow wrist. At 16.1 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. 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. 42 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.

3540.80.00 stands on its own in this catalogue — no other reference here shares its base number. It pairs a blue dial with a stainless steel case. Introduced in 1999. Beyond the time it carries a chronograph.

Introduced in 1999, caliber 3600 is a split-seconds chronograph movement based on the ETA / Valjoux 7750.
