Oscillating Weights

A mechanical watch uses an oscillating weight to ensure its functionality. It is a component that rotates freely inside the watch which creates energy that is preserved by the spring barrel through kinetic energy (movements made by the watch-bearer). This enables the functioning of watch as long as it is being worn.

For the production of oscillating weights, washers in heavy metal, produced from tungsten powder pressed and poured into moulds of different diameters are used. Once heated in the furnace (or sintering), they are calibrated and reheated in the furnace so as to avoid any torsion within the materials. Acrotec’s production means are entirely automatic, which allows the company to be competitive from the prototype size to large-sized quantities. Flawless execution is ensured thanks to effective quality control in place. The oscillating weights produced can be labelled “Swiss Made” allowing for the complete satisfaction of the internationally renowned clients.

A wide range of more than 100 different models of oscillating weight has been created in response to customer demand, such as weight segments to be assembled on brass or titanium sheets, mono-block weights etc. Acrotec carries out ébauche turning, milling, engraving and trimming, and also carries out decoration (snailing, Geneva stripes, graining, surface finishing, varnishing and pad printing). Assembly and riveting of bi-metallic balances are also possible.
