Notes

"Ingenieur" This model was made for the first time by IWC in the middle of the 1950's. With its self-winding mechanical movement, it created a sensation at the time, and has always been considered as the most resistant watch. This concept of wristwatch was meant to constantly be adapted to technical progress in the field. In 1976, the model "Ingénieur SL" antimagnetic to 80000 Ampere/Meter was launched and in 1989 the "Ingénieur R" antimagnetic to 500000 Ampere/Meter was launched. Two dates have been programmed for adjustments. The first is March 1, 2100 for the date and the moon phase indicator (the Gregorian calendar omits February 29). The movement of the moon phase indicator deviates exactly one day in 122 years. The second adjustment, replacement of the century slide, will have to be done at the beginning of January, 2200.
