This is a very specialized tool, it’s sole purpose in life is to remove the pins that hold together the links that make up a watch band. In the past I’ve used a machinist scribe to perform this task, and that is a dangerous way to do it (for the watch band and the fingers). This does the task, and does it well.
If you need to occasionally re-size a watch band, this device is a must have.
