The Aquatimer Perpetual Calendar Digital Date-Month Edition “50 Years Aquatimer” Story

The most striking feature of the Aquatimer Perpetual Calendar Digital Date-Month Edition “50 Years Aquatimer” is the matte black Ceratanium® case. A team of specialists at IWC worked for more than 5 years to develop this new material, which is based on a titanium alloy. A special manufacturing process gives the metal a black, ceramic finish. As light and robust as titanium, Ceratanium® is also as hard and scratch-resistant as ceramic. Furthermore, the material boasts high skin tolerance and corrosion-resistance. The watch features a black dial to complement the case, while the self-winding IWC-manufactured 89802-calibre has several components which are finished in black, including the rotor. The integrated digital perpetual calendar displays the date and the month with large digits in the style of a digital watch. It recognizes leap years and the different lengths of the months. The chronograph with flyback function displays stopped times combined in a totalizer at 12 o’clock.

Calibre Family 89000

The 89000-calibre family includes powerful chronograph movements with flyback function, which are used, for example, for the big digital date and month displays or for watches that display stopped hours and minutes on a subdial.

Perpetual calendar with digital date and month displays

The perpetual calendar with four display discs consists of 185 individual parts and shows the date and month with large digits in separate windows. It also features a leap year display in a small window.
