Every two years, the Only Watch, which is under the patronage of Prince Albert II of Monaco, invites luxury watchmakers to each create a unique timepiece to be auctioned off. Ninety-nine per cent of the proceeds will go towards funding research on Duchenne muscular dystrophy. A total of 54 watch brands including Chopard, Hublot, Bulgari, Chanel and Richard Mille are participating in this edition's auction, which will happen on Nov 6, 2021.
