INTRODUCING: IWC Ingenieur Perpetual Calendar Digital Date-Month in Titanium

by Hours and Minutes Australia

Titanium has been quite the favourite with watchmakers thanks to some amazing properties of the material. The Ingenieur Perpetual Calendar Digital Date-Month with large digital display for the date and month is now available for the first time with a titanium case. Here, the watchmaker has used grade 5 titanium, with higher strength and hardness widely used for making aerospace airframe and engine components.

Harnessing the qualities of this metal, is a complication that is equally versatile. The perpetual calendar has large digital displays for the date and the month. It is mechanically programmed to recognise the different lengths of the months and even adds a leap day at the end of February every four years.

The IWC-manufactured 89801 calibre movement features a chronograph with flyback function. The automatic winding system builds up a power reserve of 68 hours and features a rotor made of solid 18-carat gold.

The robust 45 mm case is apt on the wrist, and with a slate-coloured dial and black hands with luminescence… the entire watch seems all the more appealing.
