Portofino Hand-Wound Tourbillon Rétrograde 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 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. 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.

IW5165-01 stands on its own in this catalogue — no other reference here shares its base number. It pairs a silver dial with a red gold case. Introduced in 2017. Beyond the time it carries a tourbillon.
