This is an Hermès Crescendo bracelet. I purchased it in 2023 from FABULOUS SOUNDS. I have worn it about 2-3 times a month. I own a Chaine d'Ancre GM 12-link and a GM 13-link bracelet, and the size of this bracelet is about in between those. The price of vintage Hermès items continues to rise. I plan to raise the price if the market price goes up. Please feel free to ask any questions if you are interested.
