Here’s a look at Franck Muller’s contribution for the 2011 ONLY Watch charity auction.

The unique watch designed for this occasion is dubbed “Totally Switzerland” and painted in a distinctive vibrant shade of red, characteristic for the Swiss flag.

This model is a variation of the Franck Muller Crazy Hours design, which offers an innovative approach to the concept of time.

In 1875, Jules Louis Audemars, aged 22, and Edward Auguste Piguet, aged 24, founded Audemars Piguet in Le Brassus, a small village in the Swiss Jura.

This agreement entailed a workshop in the family home, a registered brand name, and a decade-long partnership contract. In 2011, the Manufacture Audemars Piguet employs almost 1,000 people in Switzerland and around the world.

The company conveys a unique culture nurtured by tradition, audacity and excellence. It also stems from an original alchemist’s blend passed on through the generations and combining respect for nature with know-how and a taste for perfection.

2011 saw the launch of the first automatic mechanical movement for Corum’s iconic Golden Bridge watch, featuring an innovative linear winding system.

Corum has take the watch to a new level for the special Only Watch event – the one-of-a-kind piece has a titanium case with a matte finish and provides great views of the movement from both the dial, case-back and sides of the watch.

The back of the watch is specially engraved with the Corum logo and the “Only Watch Piece Unique” inscription in red

Girard-Perregaux‘s contribution to this year’s Only Watch auction is a unique version of their worldwide time control model.

The entire piece has a very soft, smooth look to it, with rounded edges on the case, chrono pushers and strap.

Girard Perregaux used ultra-light titanium oxide to produce the white single-piece watch-case middle, and the thin bezel is made of ceramic.

Chanel created a different version of their J12 Diver Watch in celebration of Only Watch 2011.

The case, in sand-blasted black ceramic and 18kt rose gold, measures 38mm. It has a sapphire crystal and is water resistant to 300 meters.

Movement is a Swiss automatic (base ETA) with a power reserve of 42 hours.

Luxury timepiece maker Audemars Piguet will be once again present to Only Watch 2011 with the Jules Audemars Gstaad Classic.

This one-of-a-kind model in pink gold features a caseback engraved with the inscription “Audemars Piguet Only Watch – Gstaad Classic – 2011″.

Its dial is inspired by the 1920s, lending a discreetly vintage touch that contributes to an aesthetic that is at once chic and sporty, classic yet contemporary.
