IWC’s Mystery Machine

The Tourbillon Mystere from the Portugieser family has always been a fan favourite. The oversized case with floating Tourbillon gave the viewer an unadulterated perspective of the floating Tourbillon that appears to levitate & whirl quite magically within its carriage. It is this element that provides the mystery part of the name.

Model ref: IW504602 – UK RRP £79,950.00

2015 saw a restructure to this iconic line. The name was universally changed to become Portugieser adding a continuity & solidity to easily IWC’s flagship collection. Furthermore, the models that carried “in-house” movements, those specifically developed by IWC, have also undergone a slight change to the cases. Typically oversized, though appealing to a wide audience…these watches did not always fit well on slimmer wrists.

By curving the lugs further down, they appear shorter than the previous incarnations but allow the head of the watch to sit more snugly on almost every wrist. As always, further updates are done within the mechanism but the main complications remain steadfast parts of the family; namely, this beautiful Tourbillon Mystere Retrograde.


THe Tourbillon is considered to be one of the most difficult mechanisms to create within watchmaking given its microscopic size & intricacy. Created by Abraham Louis Breguet in 1801; the Tourbillon was created to act as a regulator to the mechanical movement, which could be prone to losing or gaining time. Aesthetically looking like a whirlpool, it was named as such in French. Typically a modern Tourbillon will rotate once every minute on its axis within its carriage – created a lovely visual effect of balance and beauty.

Tourbillon Mystere 2015

The IWC Portugieser Tourbillon Mystere Retrograde is delivered in a 44.2mm 18ct Red Gold case (officially titled 4N allowing for a deeper red hue) with sapphire caseback & Santoni strap, exclusively made for IWC. In tradition with the Mystere family, the floating Tourbillon sits at 12 to give it maximum visibility but an added retrograde date (the hand jumps back to 1 after hitting 31) feature is a new and welcome feature. An IWC own Pellaton winding system offers a 7 day power reserve once fully charged via the self winding system.
