Abstract (en)
[origin: US4692033A] A timepiece includes an outer caseband 3 formed entirely in one piece of a hard material which likewise includes a hub member 4 providing the timepiece dial, and a metallic inner caseband 16. An annular step 10 for positioning and glue fastening a crystal 9 surrounds the hub member. This arrangement gives the hard material the rigidity necessary to resist forces acting thereon during manufacture and subsequently when the watch is worn.
