IWC introduced its first Aquatimer (Ref. 812AD) in the year 1967. This diver’s watch, water-resistant up to 200 metres, had an internal rotating bezel for setting the dive time.
Even the watch is already 50 years I would say it still looks new and fresh. That´s for sure not an oldie, this design is iconic.

The IWC Aquatimer Perpetual Calendar Digital Date-Month Edition “50 Years Aquatimer” (Ref. IW379403) celebrates the first 50 years of the Aquatimer and therefore is limited to 50 pieces.
Its newest feature is the Ceratanium case. The material, a particular composite based on a titanium alloy, was developed in more than five years. The manufacturing process gives the metal a black, ceramic-like surface. As a result, Ceratanium is as light and unbreakable as titanium, but also as hard and scratch-resistant as ceramic.
The IWC Aquatimer Perpetual Calendar Digital Date-Month Edition “50 Years Aquatimer” (Ref. IW379403) features a mechanical flyback-chronograph movement (IWC developed and manufactured Calibre 89802) with a perpetual calendar that has large doubledigit displays for both the date and month and a leap year indication. The Stopwatch function indicates hours, minutes and seconds. The hour and minute counters is combined in a totalizer at 12 o’clock. The automatic-calibre has a power reserve of 68 hours.
The Ceratanium case – diameter 49 mm (!!) / height 19,5 mm – is equipped with a mechanical external/internal rotating bezel with the IWC SafeDive system. The IWC SafeDive system ensures that the internal rotating bezel can only be adjusted when the external bezel is rotated in an anticlockwise direction. Luminescent elements are applied on hands, dial and the internal rotating bezel. The Ceratanium case, waterproof up to 100 meters, also features a screw-in crown and a see-through sapphireglass back.
