Portugieser Eternal Calendar Platinum / White

In Context

At 44.4 mm it is a large watch — well above this catalogue’s 40 mm median, and enough to dominate a narrow wrist. At 14.9 mm it is a tall case, and it will catch on a cuff. The case back is open, so the movement is visible without taking the watch apart, and the sapphire crystal will resist everything short of deliberate abuse. 50 m covers rain and hand-washing comfortably; it is not a watch to swim in.

The movement winds itself from the motion of your wrist.

IW5057-01 stands on its own in this catalogue — no other reference here shares its base number. It pairs a white gloss dial with a platinum case. Introduced in 5057.
