The Portugieser Tourbillon Mystère Rétrograde combines the magic of a floating tourbillon with the logic of a date hand that reverts to its starting position and the power of a 7-day in-house calibre. In 2015, this exclusive timepiece is even more attractive to look at. The Portugieser Tourbillon Hand-Wound with its delicate, flying “whirlwind” will remain a source of delight to connoisseurs of precision watchmaking.
To mark the 75th anniversary of the Portugieser watch family, IWC has given the Portugieser Tourbillon Mystère Rétrograde (Ref. 5046) an additional touch of luxury. The new arched-edge front glass makes the watch appear both slimmer and more elegant. The horns have also been ergonomically optimized to make the watch more comfort- able to wear on a slimmer wrist. Another new feature is the exclusive alligator leather strap by Santoni:a fitting accessory for the Portugieser Tourbillon Mystère Rétrograde. The dial of the platinum version is silver plated while the red gold model is fitted with as late-coloureddial.Thereverse side of the watch with its see-through sapphire-glass back is also more attractive. The narrower and partly perforated solid red gold rotor with its “Probus Scafusia” relief engrav- ing provides a generous view of the IWC-manufactured 51900 calibre.
