The Portuguese (or Portugieser) watch family now includes a model featuring large double-digit displays for the date and month: the IWC Portuguese Perpetual Calendar Digital Date-Month Edition "75th Anniversary" (Ref. 3972).
The 45 mm wide and 16.5 mm thick case houses the 4 Hz (28,800 vph) IWC-manufactured 89801 calibre featuring a perpetual calendar as well as an integrated flyback function that enables the user to reset the running stopwatch hands to zero simply by pushing the button, and to start another timing sequence immediately. The hour and minute chronograph counters are combined in a totalizer at 12 o’clock.
This way, the dial combines two analogue displays (time and chronograph) with three digital ones (date, month and leap year) so offering the ideal visualization method for each type of indication.
The perpetual calendar can be set easily using the crown. It will not require correction until 2100, a year that breaks with the conventional 4-year cycle and will not be a leap year.
The energy required to advance the month display discs is built up continuously throughout the month by a quick-action switch. A spring-loaded lever on the quick-action switch is lifted a tiny bit further each day by a cam. At the end of the month, when the tension in the spring has reached its maximum, it is time for all that energy to be released; the quick-action switch jumps instantaneously to its starting position and advances both of the month display discs individually, or together, by one position, depending on the month. On 31 December, the leap year disc is also advanced at the same time.
This exclusive timepiece is limited to 25 pieces in platinum (ref. IW397201) and 75 pieces each in 18-carat red gold with either a black (ref. IW397202) or silver-plated (ref. IW397203) dial.
The see-through sapphire-glass back provides a view of the movement with the skeletonized rotor and the inset "Probus Scafusia" medallion made of solid red gold.
The new IWC Portugieser Perpetual Calendar Digital Date-Month Edition "75th Anniversary" has indicative retail prices of Euro 45,000 for the red gold versions and Euro 57,000 for the platinum one. iwc.com
