IW3536-01Ref

Debuting in 1998, the IWC Aquatimer 3536 served as the diver's timepiece for the athletic GST line, reviving a moniker IWC originally debuted in the late 1960s. This model houses a 42mm titanium or steel case with a rotating outer bezel and accepts an integrated bracelet, velcro strap, or later-model rubber straps. The IW3536-01 is crafted entirely from titanium, while the corresponding velcro strap with titanium lugs is identified as A04920.
