Independent watch Manufacture for mechanical movements – from R&D through manufacturing to assembly
Concepto Watch Factory SA
La Chaux-de-Fonds, CHNew on Amplifa
Independent Manufacture
Concepto Watch Factory SA is an independent Manufacture based in La Chaux-de-Fonds that develops and manufactures mechanical movements entirely in-house. Its range of services includes research & development with 3D design and prototyping, machining with 5-axis machining centers, CNC lathes, electro-discharge machining and laser cutting (ML-5), tool and stamping-die manufacture (étampes) as well as the DTR department for décolletage, taillage and roulage. The Manufacture produces its own assortiments (balance, hairspring, pallet fork, escape wheel) with internally developed alloys and offers decoration and finishing such as anglage, poli noir, Côtes de Genève, perlage and femto-laser decoration. In the horlogerie atelier covering more than 500 m², garnissage, assembly and case fitting (emboîtage) are carried out, including for Grandes Complications. Technical metals and precious metals are processed; customers come from the watch industry, in particular brands with private-label movement manufacturing.
