US 7,946,755 B2 · Watch movement

Abstract

A watch movement, includes a frame (10, 11, 20, 22, 24), defined by a first and a second parallel plane surface and defining reference planes (A, B), the second plane (B) being located alongside the movement for placing adjacent to the wrist of the wearer, at least one balance wheel (30), pivoting in bearings fixed in the frame, at least one escape mechanism (26, 28) providing support for the balance wheel, an energy source (12), clockwork finishing movements (14), connecting the energy source to the escape mechanism and motion work (42).The balance wheel turns about an axis (YY), inclined in relation to the reference planes and intersecting the same, the point of intersection (PA) of the axis (Y) with the first plane (A) being closer to the center of the movement than the point of intersection (PB) of the axis (Y) with the second plane (B).

Dependent claims

A watch movement comprising a frame, limited by first and second parallel plane surfaces and defining first and second reference planes, the second plane being on the side of the movement designed to be adjacent to the wrist of the wearer, and which comprises:

at least one balance, said balance having an arbor which pivots in bearings secured in said frame,
at least one escapement allowing to maintain the balance,
an energy source,
a going train wheel assembly connected the energy source to the escapement and a motion work wheel assembly,
wherein said balance oscillates around an axis inclined in relation to said reference planes and intersecting them, the point of intersection of said axis with the first plane being closer to the center of the movement than the point of intersection of said axis with the second plane.
