Great little tool. A must have if you have watches.

Make sure you push the pin out from the correct side. One side normally has the compression and that side  will have a line that appears its for for a tiny flat head screw driver, don't push that side in!!! thats the side you want to push out. See attached picture so you can see its construction and you will understand why it looks like that.

The tool can be used to push the pin all the way back in as well, normally its just the very tip with compression you cant push in by hand, so you don't really need that tiny hammer.

FYI, my only negative would be that the black version does scratch easy and shows the silver, but its a tool so who really cares. Five stars for it not being made of plastic! Great tool at this price point!
