Corum’s New Admiral’s Cup Challenger 44 Chronograph Rubber Written by WatchTime, August 24, 2012 Corum has introduced a new Admiral’s Cup watch, the Admiral’s Cup Challenger 44 Chronograph Rubber. Available in several color variations, this watch comes with vulcanized rubber strap made by a high pressure injection procedure which gives the rubber a matte look and soft texture. The automatic CO 753 movement, certified by the COSC, is held in a 44mm-diameter case. Each color will be available in limited quantities: the chocolate-tone will be limited to 50 pieces, grey (seen below) and green will have 70 pieces, and the orange version (below) will be available in a 120-piece limited edition.
