Timepiece construction |
摘要 |
A precision, reliable, analog timepiece uses plastic frame elements reinforced with metal, and plastic wheel and pinions pivoting in holes formed in the plastic of the frame elements. The plastic frame elements are separated into portions corresponding to the functional timepiece portions. Exposed areas of the reinforcing metal provide reference locations in molding the frame elements and for component mounting. The entire timepiece is assembled from one side of a base frame element.
