Only Watch comes around once every two years in aid of Duchenne Muscular Dystrophy. This year the auction is set to take place on November 9th at Christie's Geneva.

Up for auction are 52 novelties, each one of them a one-off, from some of the world's finest watchmakers. This year's Only Watch auction is on course to beat 2017's record-breaking haul of over $12 million dollars.

Watches, from a cluster of top Swiss brands, ranging from the eye-watering sums which will be bid for a Patek Philippe unique piece to the more down to earth offerings such as this one of a kind Aikon Mercury from Maurice Lacroix.

At first glance, the 44mm AIKON Mercury appears to be a normal watch, with central hours and minutes and small seconds at the six o'clock position. But with the slightest tilt the blue hour and minute hands spin freely, abandoning their chronometric duties.

Hold the AIKON Mercury upright, and the hands fall back and give the correct time. This is the secret of the AIKON Mercury. Like time, it slips away when you're not paying attention and then reasserts itself when needed.

The patented mechanism behind this display took 3 years to develop and perfect in the Manufacture facilities of Maurice Lacroix in Saignelégier.

You may not be able to get your hands on the Only watch piece but there is an unlimited version of the watch coming out in mid-September of this year which will cost US$7,690.
