For the 50th Anniversary of the Aquatimer, IWC is debuting a brand new titanium-based case material called Ceratanium. In development for more than five years, the material has the lightweight qualities of titanium and the hardness and scratch resistance of ceramic while also having a high skin tolerance level and corrosion resistance.
The 49mm case houses an in-house automatic movement that features a perpetual calendar, chronograph functionality, a flyback, a 68 hour power reserve and also has a mechanical external and internal rotating bezel with SafeDive system. Other details include convex sapphire crystal with antireflective treatment on both sides, a black rubber strap, and IWC's quick-change strap system.
The watch will be limited to 50 pieces and will be available at IWC boutiques this month.
