IWC Portuguese Tourbillon Mystere

The IWC Portuguese Tourbillon Mystere brings new fascination to watchmaking’s most illustrious high complication. With a superb IWC manufacture movement that features an exceptional power reserve, the Tourbillon Mystere's intricate flying tourbillon boldly defines why A.L. Breguet's ingenious "whirlwind" has always been such a profound source of wonder for admirers of brilliant mechanics.

The heart of the IWC Portuguese Tourbillon Mystere is the automatic-winding manufacture calibre 50900. Utilizing the innovative and efficient winding system that was developed by engineer and watchmaker Albert Pellaton, this movement also features a long power reserve of seven days, the status of which is shown on an indicator at the 4 o'clock position.

The Portuguese Mystere's tourbillon is of the cantilevered (“flying”) type, being fixed to the plate, rather than anchored to a bridge; this more challenging construction allows a full view of the tourbillon's continual rotation. A particularly striking visual element of this tourbillon is its location on the dial---rather than the 6 o'clock placement that is most often seen, the IWC Portuguese Tourbillon Mystere proudly showcases the complication at 12 o'clock.

A notable technical detail of the escapement is the use of a Breguet hairspring, which contributes to the stability of the watch's rate when the movement is subjected to positional variance. The IWC Portuguese Tourbillon Mystere is available exclusively in 18K white gold. A unique and richly colored "Ardoise" dial provides a sophisticated appearance which perfectly compliments the exclusivity of the mechanism. IWC will only produce 250 examples of this stunning watch, ensuring that the reverence accorded the tourbillon complication remains sacred.
