My husband has been wanting to try and repair an old pocket watch he purchased at a flea market. He purchased a how to book so when I saw this kit I knew I had to get it for him. I was very impressed with everything that was in this kit. I have never tryied to repair a watch so I am not sure if anything is missing from this kit or not, but it appears to have everything in it you could possible want. My husband is very pleased with this kit.
