Portofino Hand-Wound Monopusher Red Gold / Silver

In Context

At 45 mm it is a large watch — well above this catalogue’s 40 mm median, and enough to dominate a narrow wrist. At 12.8 mm it is a tall case, and it will catch on a cuff. Rated to 30 m, it is protected against rain and splashes and nothing beyond that.

The movement is hand-wound, so winding it becomes part of the day rather than something the watch does for you. 192 hours of reserve puts it well past a weekend — several days off the wrist and it is still going. At 28,800 vph the seconds hand advances 8 times a second.

IW5151-04 is one of 3 executions of the IW5151 base reference. Underneath they are the same watch; what separates this one is a silver dial and a red gold case. Introduced in 2015.

Monopoussoir chronograph with 8 days of power reserve.
