Portofino Complete Calendar 41 Stainless Steel / Silver

In Context

At 41 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 11.7 mm thick it is about average for a modern wristwatch. 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. Its 27-hour reserve wants wearing most days; leave it off and it stops. At 28,800 vph the seconds hand advances 8 times a second.

IW3590-01 is one of 2 executions of the IW3590 base reference. Underneath they are the same watch; what separates this one is a silver matte dial and a stainless steel case.
