My Chaine d'Ancre bracelet fell off my wrist twice, luckily in the house. I took it to Hermès and they took off 1 link, it never came off again. Bracelets with this type of closure need to be quite tight or they do come undone. I'm sorry this happend to you OP.Not OP but i have the farandole bracelet. I actually got some of the links removed by a jeweler and i feel like the tighter it is, the more secure ( i also prefer bracelets tight bc i hate the feeling of them sliding up and down my wrists). but such a bummer for OP !!![]()
