Today I was working on a watch and one of the VERY small screws from a regulator went flying. I felt something hit me on top of my head. Bent over my bench and brushed lightly and there it was! Never would have felt it with a full head of hair

You know I have had the opposite feeling, not only do I let my hair grow to long for my wife & boss but I also have a beard. I have wondered how many of those little flying parts have become lost in there. Just today of a very small woman's wrist watch I had a winding arbor fly off into the black hole & I wondered could it be in there some where?

When I started working on watches, I thought of developing a mosquito netting system to prevent lost parts. Fortunately, I don't have the problem very often anymore. 2000 hours of practice cures a lot of it. The secret is to let the power off clic springs and set springs before you remove the parts that hold them in. The other is always keep the tweezers parallel to the bench and as close to the bench as possible. Having your tweezers properly dressed helps too. You can do this by taking some emery cloth and gripping it with the tweezers. Pull the tweezers off of the emery. Finally, always use the right tweezers for the job.

Actually our benches have a "time warp", sometimes when a part disappears, I wait a week or two and it shows up again.
