GOLD
The oldest known gold objects date back to around 5000 BC. Gold has long been esteemed as noble and precious in the majority of cultures and throughout history. As a native metal, it is easy to find, especially in alluvial deposits, and its malleability has likely contributed to its long-standing appeal.
Gold’s mechanical, chemical, and aesthetic properties have made it a favourite among watchmakers over the centuries, serving both decorative and technical purposes.
Universally recognised as rare and valuable, gold has historically surpassed the value of platinum since 2008.
Gold can be used to manufacture all external components of a watch (cases, bracelets, clasps, dials, hands, etc.). Its malleability makes it easy to polish and suitable for all types of stone setting. For the same reasons, engravers also value gold, and it is a preferred base for enamelling work. Many movement components can also be made from gold. Oscillating weights and balance screws are frequently made from this metal due to its high density. Less commonly, wheel plates, pinions, and even bridges and mainplates can be made from gold.
Gold is also widely used in galvanic treatments. The surfaces of bridges, mainplates, wheels, etc., are frequently gilded, offering protection against corrosion and oxidation while providing a specific appearance and colour.
Gold is present in tools and certain manufacturing processes (UV-LIGA, DRIE engraving), making it a metal historically inseparable from horology.
