GST Aquatimer Titanium

In Context

At 42 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 14.5 mm it is a tall case, and it will catch on a cuff. The case back is closed, so the movement stays out of sight, and the sapphire crystal will resist everything short of deliberate abuse. 2000 m is a professional diving rating, far past any demand a wrist is likely to make of it.

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.

IW3536-01 is one of 3 executions of the IW3536 base reference. Underneath they are the same watch; what separates this one is a black dial and a titanium case. Introduced in 1998.

An ETA 2892-A2 base with a 21K gold rotor weight, finished by IWC. Mechanically it is the same movement as the 37521; the two differ only in the height at which the hands sit, so that one base could serve cases of different depth. The 2892 is the thinner of ETA's two workhorse automatics and the one chosen where case height matters.

25 other watches in the library run the IWC 37524.
