The invention relates to a watch movement, comprising 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 and which comprises: at least one balance wheel (30), pivoting in bearings fixed in said frame (10, 11, 20), at least one escape mechanism (26, 28) providing support for the balance wheel (30), an energy source (12), clockwork finishing movements (14), connecting the energy source to the escape mechanism (26, 28) and motion work (42). According to the invention, the balance wheel (30) turns about an axis (YY), inclined in relation to the reference planes (A, B) and intersecting the same, the point of intersection (PA) of said axis (Y) with the first plane (A) being closer to the centre fo the movement than the point of intersection (PB) of said axis (Y) with the second plane (B).
