Aquatimer is a dive watch series by IWC.

Dive watch from the 1970s with automatic winding and date display.

The Aquatimer models have an internal rotating bezel, which is operated by a second crown at the "4". With the chronograph models this crown takes over a technically complex double function: Chrono reset by pressing and setting of the bezel by turning the crown.
