Only Watch 2017 is just around the corner and so we will be periodically previewing some of the more interesting pieces like this one-off Arnold & Son Time Pyramid in stainless steel with a black DLC treatment, while the skeletonized and symmetrical caliber A&S1615 receives a black ADLC coating.

This unique piece will also have red accents highlighting some of the components and the hands of the two power reserve indicators (one per barrel) are painted red, as are the hour and minute hands and Roman numerals on the sapphire dial. An anthracite alligator strap adds the final touch with its red stitching.

Only Watch 2017 takes place Saturday, November 11th in Geneva and is run by Christie’s auction house.

Approximately 98% of the proceeds go to fund research into Duchenne Muscular Dystrophy.

Stay tuned as we will be publishing a live preview of the timepieces as it gets closer to auction time.
