II
The perpetual calendar
A perpetual calendar knows how long each month is and when February has 29 days, so the date needs no correction for decades. The first manual adjustment falls in 2100, a year that is not a leap year in the Gregorian calendar. If the watch stops, it is set forward with the correctors rather than by turning the date day by day.
III · The manufacture
IWC since 1868
American watchmaker Florentine Ariosto Jones founded IWC in Schaffhausen in 1868. The Special Pilot’s Watch of 1936 established a lasting aviation line. In 1955, the Ingenieur combined Pellaton automatic winding with protection against magnetic fields. The Aquatimer of 1967 moved the instrument-watch idea underwater. Kurt Klaus’s crown-adjusted perpetual calendar appeared in the Da Vinci in 1985. IWC joined Richemont in 2000 and remains one of the group’s watchmaking houses. A new Schaffhausen site opened in 2018 for cases, components and movement assembly. The Portugieser Eternal Calendar won the GPHG Aiguille d’Or in 2024.

IV · Ownership
Wearing and caring
- 1
An automatic watch winds itself while worn. Left off the wrist for a couple of days it stops: wind it with the crown, then set the time and the date.
- 2
Water resistance of 100 m and more is for swimming. Keep the crown screwed or pushed in, and do not use the pushers under water.
- 3
Have the movement serviced every few years by the brand's own service or an authorised watchmaker.
