Uni-Polishing System - Clockwise This is a unique hand polishing system developed for the watch industry, particularly for watch cases. These Uni-Polish tools are composed of a vice with 4 brass claws (inside tightening) from 14 to 34mm (diameter) or 25 to 50mm (diameter). These claws are mounted on ball bearings, allowing the polishing of items without risking any flattening on the item being worked on. Ideal for watch cases, watch bezels, watch case backs, rings, etc. As soon as the Uni-Polish comes in contact with the buff, the system starts turning at the same speed as the brush. There is a back screw on the handle to completely stop this rotation, or to allow the rotation to occur. This model of Uni-Polish turns clockwise (right).
