2. Align the small pins between the watchbands to be disassembled, screw on the handle of the watch detacher and eject the small pins.

3. Put the watch band into the "slot" of the watch remover (the steel bolt with clamping needle has two ends, one is flat, the other is slotted and the other is blocked, so the sharp needle should be pushed from the flat end, not the straight end).

4. Adjust the wrist to a proper length, and then put the watch pointer back to the opposite direction of the arrow. Install the strap, but pay attention to the strap. Make sure there are no screws on the strap, but nails or hairpins. You can go from small mouth to big mouth, which is OK! No matter how difficult it is to remove the strap, it will be done in less than a minute!
