On September 20 this year, the Only Watch event will take place in Monaco again. For the event, some of the world's finest watchmakers create special unique timepieces to be sold at auction to benefit research on Duchenne muscular dystrophy. This watch is the entry from Girard-Perregaux and it is the only watch in the world to combine a perpetual calendar, the indication of time in 24 different international cities as well as the business hours of four major stock markets. The dial displays the date, the day of the week, the month and the moon phase. The mechanism takes into account the length of each month, allowing for the leap years without any manual adjustment before 2100. Two mobile rings on the dial show the opening hours of the New York, London, Hong Kong and Tokyo and the different times around the world. The watch has a 41mm pink gold case with sapphire front and back crystals. The Vacheron Constantin entry is after the jump and I will bring you more Only Watch 2007 models as they are released.
Vacheron Constantin's entry for Only Watch 2007 is a platinum timepiece, a Malte Tourbillon Tonneau-shaped watch that has a case, dial, strap stitching, buckle and a carriage bridge in 950 Platinum. It is the watchmaker's first tourbillon with a platinum carriage bridge. The dial is grained to achieve a frosted effect that highlights the texture of the metal. The navy blue alligator leather strap is hand-sewn with platinum thread.
