Some details on the watch:
The escape is a double-roller Swiss Lever with a half-second balance wheel. ...The escape has banking pins and a safety roller, so - like a watch - it runs in any position. You can even shake it or bang it around, and she keeps on ticking!
The balance wheel is in Teflon bushings and the escape wheel is on ball bearings. The pins on the balance wheel have small screws inside to adjust the poise. The cherry pallets are adjustable. The anchor for the "hairspring" (actually a very small clock spring) moves with an adjustment lever to regulate the watch. It keeps perfect time.
