The Time Arc is a true testament to Rapport's technical capabilities in creating some of the world's finest watch winders. The Time Arc's cog mechanism powering the winding heads is contained in a lead crystal glass case with a semicircular shaped, hinged lid. The edges are trimmed with chrome plated steel and the base is a combination of piano finish ebony and polished steel. Size: H: 6 x W: 9 x D: 11.5 inches
