Designed to take gladiator-level use and abuse, the Coliseum is the core of our Rider by Rockwell digital line. A multifunction digital, it features: dual time zone, chronograph with 50-lap memory, countdown timer, and 8 alarms. Case construction is ABS, and band is made of PU. The stadium-style bezel helps protect the lens from scratching.
