The IWC Aquatimer Automatic is a diver for someone who likes purposeful engineering with a slightly unconventional face. Its modern signature is SafeDive: you turn an external bezel, but read elapsed time on an internal ring, keeping the timing scale beneath the crystal without making you operate a second crown.

Generation matters here. The earlier IW356801 belongs to the larger, 44mm family with a conventional external timing bezel. The 42mm IW329001 introduced the SafeDive arrangement; the newer IW328801 and IW328802 retain that approach but use IWC’s 32111, with a substantially longer, five-day power reserve. Choose between those generations for the movement as much as the dial.

On a SafeDive example, give the bezel mechanism particular attention: the internal timing ring should advance cleanly counterclockwise, without slipping or sticking. The quick-change strap attachment is another useful detail to test—make sure it locks positively, especially if you intend to swap between rubber and bracelet.
