Portugieser Yacht Club Moon & Tide Stainless Steel / Black / Bracelet

In Context

At 44.6 mm it is a large watch — well above this catalogue’s 40 mm median, and enough to dominate a narrow wrist. At 14.4 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. 60 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. 60 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 28,800 vph the seconds hand advances 8 times a second.

IW3440-02 is one of 2 executions of the IW3440 base reference. Underneath they are the same watch; what separates this one is a black sunburst dial and a stainless steel case.

Mechanical movement with Pellaton automatic winding system. Perpetual moon phase for the northern and southern hemispheres at 12:00, and display for spring tide or neap tide plus tide indicating with the time of the next high or low tide at 6:00. Date display.

1 other watch in the library runs the IWC 82835.
