One setting workshop, two worlds of precision. Watchmaking demands consistency and repeatability; jewellery combines technical accuracy with the setter's individual expertise.
01 / How we work
Around 40 stone setters, one setting workshop, two disciplines of precision. Watchmaking demands absolute consistency and repeatability; jewellery combines technical accuracy with the setter's expertise, where each stone contributes to the balance and character of the piece.
Place, align, secure, reveal. Machined seats arrive from CNC ready for setting, with every stone positioned for precision before the final finishing stages.
From mechanical setting and posé-boulé to grain setting raised entirely by hand, the same family covers regular production and the most complex pieces.
Channel setting and invisible setting, also called mystery setting. These assemblies demand exact adjustment and alignment, and a close understanding of stone, metal and structure.
Claws bring light to the stone while holding it in place. Each setting balances the security of the stone, the delicacy of the metal and the final aesthetic.
Watchmaking pieces require perfect repeatability and constant precision. Jewellery pieces, from fine to high jewellery, leave more room for interpretation; the setter shapes the brilliance and balance of each creation.
From diamonds and colored stones in gold and platinum to steel, titanium, and advanced materials, each piece is developed from classic foundations to innovative expressions.
