Black polishing is carried out using abrasive paper to first smooth the surface and then a zinc block with diamond paste to polish the piece perfectly. Once polished, the piece will be black, grey or white depending on the orientation of the light. This technique requires a great deal of skill, with each screw taking around 30 minutes to complete, given that there are 40 screws per movement for the Classic Tourbillon Manufacture Meteorite. #ManufactureCollection #Tourbillon #Meteorite #SavoirFaire #Craftmanship #LuxuryWatch #HauteHorlogerie」10月24日 23時57分
