When diving with oxygen tanks began to gain popularity, IWC introduced the first Aquatimer in 1967. This diver’s watch, water-resistant to 200 metres, had an internal rotating bezel for setting the dive time. In 2017 IWC celebrates the 50th anniversary of the Aquatimer family with the world’s first watch with a case made of Ceratanium®.
The Aquatimer Perpetual Calendar Digital Date-Month Edition “50 Years Aquatimer” (Ref. IW379403) is limited to just 50 pieces. Its most striking feature is the Ceratanium® case, which experts at IWC have been working on for more than five years. The special manufacturing process gives the metal a black, ceramic-like surface. Ceratanium® is both light and unbreakable like titanium, but also as hard and scratch-resistant as ceramic. The material also scores well for its high skin tolerance and corrosion resistance.
