A method for making an oscillating weight for an automatic winding mechanism of a self-winding watch including a central part made from a first composite material and a heavy sector made from a second composite material charged with heavy metal particles, the method including: forming the central part with a lateral rib and a rebate by injecting the first composite material into a mold; overmolding the heavy sector onto the central part by injecting the second composite material into a mold containing the central part, so that the second composite material fills the rebate and a gap underneath the lateral rib, so that the lateral rib is embedded in the second composite material and the central part and the heavy sector are interlocked.

Oscillating weight

A timepiece wheel overmolded onto an arbor. The wheel is plastic injection overmolded onto a washer fitted onto the arbor. This washer has a lower density than the arbor. This washer includes at least one plane surface forming a bearing and sealing surface for cooperating in a sealed manner with an injection mold for the overmolding operation. The timepiece wheel may be an escape wheel whose teeth are formed during overmolding onto the arbor and the washer, and it includes an escape pinion mounted and abutted to the washer or integral with the washer.

The oscillating weight for a self-winding watch mechanism is made by molding a plastic material charged with heavy metal particles. Moreover, the plastic material is also charged with fibers, wherein said fibers form between 1.5% and 7% of the total weight of the charged plastic material, and the density of the charged plastic material is greater than 8.

The oscillating weight is intended to be used in a self winding watch mechanism. It includes a basic part () made of composite material and heavy metal elements (). The basic part includes an inner portion () and a peripheral portion (), with the peripheral portion including housings in which the heavy metal elements are set.

The invention concerns an electronic watch including analogue display means formed of at least one hand () driven by a stepping motor (), at least one time base () for providing time data (h. m) to means () for controlling and driving said stepping motor, a main power source (), means () for detecting a lack of sufficient power from said main power source, non-volatile storage means () powered by an additional power source (), for containing said time data when a lack of sufficient power is detected, and characterized in that said non-volatile storage means are further provided for containing the stepping motor position data (&#x3bc;pas) when said lack of sufficient power is detected.
