Abstract
A movement subassembly adapted for use in either a two hand timepiece or a three hand timepiece, the subassembly having a first set of elements common to both timepieces adapted to cooperate with a second set of components, including at least one intermediate wheel assembly to make up a three hand timepiece movement, the first set also adapted to cooperate with a third set of components, using a different wheel assembly to make a two hand timepiece. The second set components includes a seconds wheel assembly, an intermediate wheel assembly, a third wheel assembly and a once-per-second pulsing integrated circuit. The subassembly frame includes bearings for journaling all of said aforementioned wheel assemblies using a common subassembly.
