Polishing

Polishing a watch is a complex process divided into various stages, which require a variety of equipment and the acquired craft of the Master Polisher.
Before the polishing can take place, the case and the bracelet have to be properly cleaned. This operation is performed in an ultrasonic tank that can remove even the most resilient encrustations. Once dry, the pieces are ready to be polished.
Polishing today’s modern watchcases and bracelets requires care and attention. The polished surfaces are alternated with matte parts, which makes the polisher’s job that more complicated. The Master Polisher uses a special tape to cover either the matt or the polished parts. Soft brushes are used when polishing watches, which are covered in abrasive paste containing diamond powder. For a satin finish special brushes are used made out of metal wires which when rotated cause a series of extremely thin scratches. Both processes require extreme care in order to obtain a uniform result and the appropriate machinery must be used.
Watches have recently seen an increase of sanded areas, which are created using a special machine that produces a strong blast of sand that can be directed, using a nozzle, onto the part to be machined.
If the watch cases are rhodium-plated (as is often the case for plated watches or those made out of white gold), the rhodium removed during polishing is applied once more, directly at our Servicing Centre, thus ensuring the ultimate purity of each rhodium-plating bath.
Once the polishing process is completed, the parts are washed once more in an ultrasound tank, to remove any milling residue, and then dried under a jet of hot air, produced by a special machine that doesn’t leave any haloes.
