Speedmaster Day Date 40 Stainless Steel / Mark 40 / Bracelet

In Context

At 39 mm it sits just under the modern norm — the band that suits the widest spread of wrists. The case back is closed, so the movement stays out of sight, and the sapphire crystal will resist everything short of deliberate abuse. 50 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. 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.

3520.53.00 stands on its own in this catalogue — no other reference here shares its base number. It pairs a grey dial with a stainless steel case. Beyond the time it carries a chronograph.

Full Calendar Chronograph based on ETA 7751. Replaced the 1150 in 1994.
