Portuguese Perpetual Calendar

The manufacturer has treated the Portuguese Perpetual Calendar, its specialist for long calendar periods, to a gentle facelift and an extension to the model range: two new
variants in red gold and two in white gold increase the variety of models on offer. Technically, there was nothing left to improve. This time machine with its perpetual calendar
stands for sheer perfection.

It is the Portuguese watch which one might easily have imagined on the wrist of famous seafarers. Learned individuals with the necessary far-sightedness, spirit of discovery and a concrete vision of the future. Because the future is precisely the area of expertise of this particular time machine, which is as beguiling as it is technically impressive. The perpetual calendar, invented 25 years ago, lives on here in all its original complexity and genius – in conjunction with an IWC-manufactured large movement from the 50000-calibre family with a seven-day power reserve.
