Hi Whats the possibility of building a frame fitted to the desk with an overhead flourescent tube or double tube assembly over the work area, Inconjunction with the desk lamp it should minimise the shadows. If the height is made adjustable up/down it would be even better.
My first watch was a Adram divers watch with a EB 8012 movement. This was a birthday present and was subsequently the first way I attempted to repair (age 11). Ironically a few years ago my brother found it and I re-furbished it as it runs great.
I have a similar one but with a cowboy! Somewhere I have a cowgirl too. It is indeed the pallet fork that gives the motion.
My first watch was a Frogger watch, followed by a first gen G Shock. Then a quartz Seiko diver, and finally got an Omega automatic just before I went to watchmaking school. I didn't want to show up with a quartz.
