IWC Aquatimer Chronograph 43mm Men's Automatic Steel Watch

The IWC Aquatimer Chronograph 43mm adds elapsed-time measurement to the Aquatimer's proven 300-metre diving specification, creating a dual-purpose instrument equally capable of tracking dive times and surface intervals with the precision of a Swiss flyback or column-wheel chronograph movement. The 43mm stainless steel case retains the Aquatimer's defining technical innovation — the patented internal/external bezel system that allows safe operation of the elapsed-time countdown bezel without compromising water resistance integrity — while integrating the chronograph pushers with the case architecture in a manner that maintains the collection's clean, functional profile. The dial presents the Aquatimer's characteristic high-contrast luminous layout alongside two chronograph sub-registers for elapsed minutes and running seconds, readable in the low-visibility conditions of an active dive. Screw-down crown and case back. Swiss self-winding movement. Rubber strap with secure deployment. The complete IWC diving instrument.
