Portugieser Tourbillon Hand-Wound White Gold / Green / Middle East

In Context

At 43 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. 54 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.

IW5463-07 is one of 6 executions of the IW5463 base reference. Underneath they are the same watch; what separates this one is a green dial and a stainless steel case. It was a limited edition. Beyond the time it carries a tourbillon.

Mechanical movement with flying minute tourbillon at 9 o'clock and small seconds at 6 o'clock. Plate and three-quarter bridge made of nickel-silver.
