IWC Aquatimer Chronograph 44mm Steel Black Rubber IW376803

The IWC Aquatimer Chronograph Reference IW376803 is a professional dive chronograph combining robust underwater capabilities with IWC’s refined engineering. The 44mm stainless steel case features a rotating bezel with the patented SafeDive system, preventing accidental over-rotation of the dive time indicator.

The black dial provides maximum contrast for legibility at depth, with luminescent hands and markers. Powered by the Calibre 79320 self-winding chronograph movement with date and day display, it delivers approximately 44 hours of power reserve. The screw-in crown and case construction ensure water resistance to an impressive 30 bar (300 meters). Fitted on a black rubber strap with pin buckle for secure underwater wear.
