Digital Date Display

IWC produced the first “digital” watches in its history as early as 1884. These timepieces, known as Pallweber watches, displayed the hours and minutes using numerals, while the seconds were shown in analogue form with a hand. In 2009, IWC unveiled a surprise for watch lovers in the form of a newly developed perpetual calendar movement, which shows not only the date but also the month in large numerals. In 2013, the year of the Ingenieur, tinted glass inlays on the dial of the Ingenieur Perpetual Calendar Digital Date-Month provide a view of the discs at work. 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, the tension in the spring has reached its maximum, and 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.

MANUFACTURING EXPERTISE PACKED INTO 45 MILLIMETRES

The digital perpetual calendar is one of IWC’s most outstanding technological advances. With the new Portugieser Perpetual Calendar Digital Date-Month Edition “75th Anniversary”, the Portugieser (Portuguese) watch family now includes a model featuring a digital display for the date and month. 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. Every night, when the date display moves forward, the switch siphons off a little of the energy, stores it and then discharges it precisely at the end of the month or year when, in addition to the date and month disc, the leap year disc also needs to be advanced. The perpetual calendar can be set easily using the crown and will not require correction until 2100. On the occasion of its relaunch to mark the 75th anniversary of the Portugieser family, the watch is fitted with an arched-edge front glass and Santoni alligator leather strap and has an attractive new calibre design. The watch is limited to 25 pieces in platinum and 75 pieces each in 18-carat red gold with either a black or silver-plated dial.
