I may not be able to fix a broken watch, but I do not blame this set of tools.
I have a dead self-winding Bulova I wanted to see if I could puzzle out, and fix on my own. That did not work out, but these tools are wonderful to have around. I can open cases of watches I previously had to take in for battery replacement, and changing, or resizing bands got a lot easier.
I find I use this set for a lot more than trying to fix a watch, too. Eye glasses repair and just about anything that needs tiny screwdrivers and picks will benefit from keeping this toolkit handy.
At least my Timex Mickey is running again.
