Every two years, the Only Watch biennial charity auction, which is under the patronage of Prince Albert II of Monaco, invites luxury watchmakers to create unique timepieces that are sold. Ninety-nine per cent of the proceeds go towards funding research on Duchenne muscular dystrophy, a genetic disorder marked by progressive muscle degeneration and weakness. A total of 54 watch brands including Chopard, Hublot, Bulgari, Chanel and Richard Mille are participating in this year's edition, which will happen on Nov 6, 2021.
