This is a tool for replacing the leather straps (belts) of Hermes watches. It features the "Clou de Forge" design, which is also used in accessories such as rings, necklaces, and bangles. This accessory was included as an attachment when I purchased a watch at an Hermes boutique. I believe this tool is a very valuable item because it is not for sale. It should fit any watch with an interchangeable strap structure. (Such as Cape Cod, H Watch, Nantucket, Arceau, etc.) Replacing the strap is a delicate task, but this tool makes the job easy and stress-free. Also, you can replace the strap without damaging your nails. *Please refer to the continuous photos for instructions on how to use it. Instructions are not included. Size: Length: 58mm Width of handle: 7mm Hole diameter: 1mm I have used it about 2 or 3 times, so there is a little bit of wear, but it is in very clean condition overall. There are no stains or scratches. Please check the photos for details. Thank you.
