Aquatimer Automatic Stainless Steel / Blue / Rubber / Expedition Jacques-Yves Cousteau

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 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. 300 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.

IW329005 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.

Similar to 30110 - eta 2892-A2 base. Slightly higher cannon pinion.

7 other watches in the library run the IWC 30120.
