How to remove the watch band:1. Make sure you are on a flat surface (table or table). Place the watch on a cloth or towel to avoid scratching.2. Take the table below. Press one end of the spring rod from the back of the watch, use the "spring rod remover tool", and use the spring rod to remove the fork (fork) end of the tool between the lug and the strap. The spring rod removal tool has a tool that will grab the ridge and allow it to compress.3. Apply a slight pressure to the strap (away from the lug) to depress the spring lever. At the same time, applying some downward pressure, the spring rod will pop out. Once again, you just took the table band from the case.How to install the strap:1. Make sure you are on a flat surface (table or table). Place the watch on a cloth or towel to avoid scratching.2. Insert the spring strips into the holes on both sides of the belt. Push them all in and center them inside the strap.3. Install the short end of the strap (the side of the buckle is at 12 o'clock). Insert the end of the spring rod into the hole in the case lug from the back of the watch. Use the spring lever removal tool (forked "fork" end) to press the other end of the spring rod into the hole in the lug. Make sure that both spring bars are in their holes by pulling them slightly, or that the straps are coming off the watch. Give it a little drag to make sure it is safe.4. Repeat the above steps on the other side. The long end of the strap (with holes) is at 6 o'clock.Package Included:*1 set of case back bottle opener kit (15 molds)
