IWC – PORTUGUESE Tourbillon Hand-Wound "Metropolitan Boutique Edition"

IWC – PORTUGUESE Tourbillon Hand-Wound "Metropolitan Boutique Edition" NEW

 TOURBILLON: A TOUR DE FORCE

In the Portuguese Tourbillon Hand-Wound “Metropolitan Boutique Edition”, the “whirlwind” – as the word tourbillon translates – revolves on its axis at “9 o’clock” on the dial; or, in nautical terms, at 270 degrees west. The sight of the mechanical, cantilever-mounted minute tourbillon invariably attracts rapt attention from watch lovers. The tourbillon rotates around its own axis once every 60 seconds to counteract the pull of gravity on any disequilibrium in the balance wheel that would adversely affect the watch’s rate and accuracy.

The arched-edge front glass gives the watch a more classical and balanced appearance and optically reduces its height. The unique olive coloured dial was choosen to perfectly match the 18-carat red gold case.

The IWC-manufactured 98900-calibre movement with its intricately decorated nickel-silver three-quarter bridge can be admired through the transparent sapphire-glass back. It belongs in the long tradition of the 98 calibre, which was first designed for hunter pocket watches in the 1930s and has since been continuously improved.

For this model, IWC’s engineers increased the balance frequency to 28,800 beats per hour, which guarantees excellent precision. The Portuguese Tourbillon Hand-Wound “Metropolitan Boutique Edition” comes with a dark brown Santoni alligator leather strap.

New addition to the Christophe Claret collection at the Geneva exhibition – X-TREM-1 

in white gold and slate blue PVD titanium

Christophe Claret is pleased to present X-TREM-1 Blue at the brand’s exhibition at the Four Seasons hotel in Geneva from the 18th to the 22nd of January, 2015. This timepiece features a white gold and grade 5 titanium case treated with slate blue PVD, plus a matching marine blue alligator-skin strap. The X-TREM-1 has become one of the most popular watches of the brand and this blue version is as visually striking as it is technically innovative.

Christophe Claret has always focused on developing original timepieces incorporating the latest technological innovations. The brand is known for pushing the boundaries of mechanical watchmaking and straying away from the beaten horological path. First presented in 2012, X-TREM-1 is a testament to this endeavor and represents a totally new way of telling the time.

X-TREM. The concept certainly deserves its name. It expresses Christophe Claret’s determination to continue pushing the boundaries of mechanical watchmaking, integrating certain fields of research never previously applied in this domain.
The Manufacture from Le Locle presents the first creation in a new X-TREM collection that will be exceptional in all ways. X-TREM-1 features a tourbillon timepiece and uses magnetic fields to indicate the hours and minutes.

X-TREM-1 Blue displays hour and minutes by means of two tiny hollowed stainless steel spheres
isolated within sapphire tubes on both sides of the caseband. The whole mechanism is revolutionary:
the two spheres – which appear to be floating in their respective tubes – are controlled by magnetic
fields generated by two magnets moved by ultra-thin surgical silk thread. Thanks to the magnetic
fields generated by the magnets, the spheres have no mechanical connection to the movement and
float inside the tubes, as if by magic. Crucially, the magnetic fields are precision-focused so that they
have no effect whatsoever on the movement – apart from the task assigned to them, which is to
display time in an incredibly original way. Time is read against a metalized scale on each tube, hours
on the left, minutes on the right.

X-TREM-1 Blue features a white gold and slate blue PVD titanium case and is available in a limited
edition of eight pieces.
Christophe Claret is an haute horlogerie brand whose exclusive timepieces are available in four
collections: Traditional Complications Line, Extreme Watches Line, Casino Game Watches and Ladies’
Complications Watch Line. In its own special way, each timepiece is an expression of the values that
define and distinguish the master watchmaker himself: innovation, perfection, passion, uniqueness
and exclusivity.
