The GST Aquatimer IW3288-01 (aka: IW328801), seen from the bench
The IWC GST Aquatimer IW3288-01 is a stainless steel professional diving instrument launched in the late 1990s as an evolution of the GST concept. The case measures 42mm in diameter with a 20mm lug width and houses the IWC caliber 32111 automatic movement, featuring hours, minutes, seconds, and date window at three o'clock. The stainless steel construction offers water resistance for controlled diving while maintaining durability without aesthetic pretense.
