ELECTROLYSIS

Electrolysis is a process that triggers chemical reactions by means of an electric current: immersed in a conductive bath (the electrolyte) and connected to a current source, the electrodes initiate controlled deposits or transformations of matter. In watchmaking, electrolysis is the basis of many galvanic Surface treatments: Gilding, Rhodium plating, nickel plating, which deposit a fine protective or decorative metallic layer on the components of the Movement and the External parts (case, dial, hands). It also plays a part in the Anodising of Aluminium and Titanium, which colors and hardens their surface, as well as in certain manufacturing processes such as Electroforming. These techniques require rigorous Testing of the bath composition, voltage, and duration, since the thickness and quality of the deposit depend directly on them. Discreet yet omnipresent, electrolysis combines chemistry and electricity in the service of protecting, coloring, and finishing watchmaking parts.
