The Aquatimer collection by IWC is celebrating its 30th birthday with the launch of a new model that the brand decided to clothe in an all-black livery. To achieve this, it devoted five years of R&D to developing a new material more resistant than a DLC-treated metal, the solution generally used in the watch industry for black cases. Ceratanium®, a titanium alloy featuring a ceramic surface, boasts the combined advantages of the two materials in terms of lightness, sturdiness as well as resistance to scratching and corrosion.
The functions of the Aquatimer Perpetual Calendar Digital Date-Month Edition “50 Years Aquatimer” are a fine match for its high-tech case. The flyback chronograph is combined with a digital perpetual calendar indicating the date and month with large numerals placed on either side of the hours and minutes counter. The disks are visible through the honeycomb grid that gives the dial a very technical look. The internal and external rotating bezels are a reminder that this imposing matt black 49mm timepiece belongs to the diver’s watch family.
