The Portugieser Perpetual Calendar Digital Date-Month Story

With the Portugieser Perpetual Calendar Digital Date-Month, the Portugieser watch family also includes a model featuring a large display for the date and month. The blue dial with a sun-pattern finish wonderfully accentuates the 18-carat red gold case, the date windows and the gold hands and indices. This exclusive timepiece packs a wealth of IWC watchmaking expertise into its 45-millimetre case: perpetual calendar, digital large date display, leap year display, chronograph with flyback function and the IWC-manufactured 89801 calibre with its efficient double-pawl winding mechanism and quick-action switch. The perpetual calendar can be set easily using the crown and will not require correction until 2100. The totalizer at “12 o’clock” displays the combined hours and minutes for stopped times, enabling the user to read off even relatively long stopped times at a glance. This watch is equipped with an arched-edge front glass and black alligator leather strap from Santoni.

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.
