Our watch cover is available in brown or black. It fits most gents' watches, but you will need to remove the band from your watch, or have a jeweller do it for you, and replace the pins. There is a strap inside the cover which will thread through the pins under the watch. A brass rivet, included with the pouch, secures the strap to the cover. The strap does not have any holes for the rivet so you can adjust it to the size of the watch. Once you have the correct size, punch two small holes (with a small screwdriver) into the strap and fasten the rivet. Measures: 42mm diameter and 12mm deep.
