Portugieser Regulateur Tourbillon Platinum / Silver

In Context

At 44 mm it is a large watch — well above this catalogue’s 40 mm median, and enough to dominate a narrow wrist. At 12.3 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. 46 hours of reserve carries it overnight, but not through a weekend in a drawer. At 18,000 vph the seconds hand advances 5 times a second, the slower and more audible rate of an older design.

IW5446-01 is one of 3 executions of the IW5446 base reference. Underneath they are the same watch; what separates this one is a silver dial and a platinum case. It was a limited edition. Introduced in 2008. Beyond the time it carries a tourbillon.

Hand-wound movement with tourbillon escapement and regulator-style display.
