This Antique 9k Pocket Watch with Key is a vintage piece with a classic design. The manual mechanical movement adds a touch of charm to this analogue display watch, while the yellow gold case and key give it a sense of nostalgia. Although it is not water resistant, this pocket watch is a timeless accessory for men looking to add a unique piece to their collection. The watch does not come with papers or a manual, and has not been customised, making it a pure and authentic vintage find. I don’t know how to open the watch to reveal the movement. To be honest I don’t want to try incase I do some damage the watch works as it should winds up and you can set the time lovely old watch
