admin-ajax Written by: K. Amanuel

IWC Schaffhausen unveils the IWC Perpetual Calendar Digital Date-Month with perpetual calendar and large digital display of the date and shows its love for innovation and ingenuity. The watch has a sporty design and unique features and pays special homage to the partnership between Schaffhausen and Formula 1 team Mercedes AMG Petronas.

This IWC Perpetual Calendar Digital Date-Month will be in a case made of titanium aluminide (TiAI), which is first for IWC Schaffhausen timepiece and took 3 years for specialists to master it. This alloy is lighter and tougher than pure titanium. The crown, push buttons, screw heads are made of black high-tech ceramic (zirconium oxide). The combination of titanium aluminide and ceramic in the case makes the watch tough and resistant to heat and mechanical wear and tear.

Inside the case is the movement that powers this Perpetual Calendar Digital Date-Month watch. The movement has 474 individual parts and can build up a power reserve of 68 hours. Through the transparent sapphire-glass back on the reverse side of the watch, one can observe that the rotor has a shape of wheel rim.

The black and white dial looks complex and reminds one of Formula One steering wheel. There are four totalizers that are grouped around the central axis with over-sized numerals in the perpetual calendar, which shows date and month on a large digital display. The central chronograph shows the measured times up to 60 seconds. The hours and minutes times are on a counter at the 12 o’clock position. The integrated fly-back function resets the chronograph at a current timing and restarts a new one. There are cut-out sections in the middle of the subdials that reveal the arbors of the sophisticated disc mechanism. The 4-year leap year cycle is shown digitally. The dial also has semitransparent sapphire-glass inlays over the date, month and leap year discs. The five displays move simultaneously on New Year’s Eve.
