Portugieser Tourbillon Rétrograde Chronograph Platinum / Blue

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 17 mm it is very tall, and sits high off the wrist. 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 winds itself from the motion of your wrist. 68 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.

IW3940-07 is one of 6 executions of the IW3940 base reference. Underneath they are the same watch; what separates this one is a blue dial and a platinum case. It was a limited edition. Introduced in 2024. Beyond the time it carries a chronograph and a tourbillon.

IWC caliber 89900 is an in-house movement pairing a flyback chronograph and retrograde date indicator with a tourbillon escapement. It was introduced in the 2017 Da Vinci Tourbillon Rétrograde Chronograph. Details to be confirmed.
