Well, the watch as a moniker sort of gave some of it away, but my first thought was and adjustable lap for pistons, I must be working on engines too much. I found that water jet is often the cheapest way even when only one or two of something are being made, even in something as simple as aluminum plate. I had a couple brake caliper mounts for converting drums to discs on a Harley trike, and had them cut by water jet because the ten bucks or so apiece was cheaper than cutting them by hand with a band saw. John, I didn't know you weren't supposed to leave marks on the back of watches when you tear them apart, I always figured no one would notice them at the dump.
Cheers, mad jack
