Breitling Endurance Pro

At 38mm the Endurance Pro is sized for athletes who want the watch to vanish on the wrist during a race. The case is moulded from Breitlight, a proprietary polymer composite dramatically lighter than titanium, harder than steel, non-magnetic and hypoallergenic against skin over long efforts. A thermocompensated SuperQuartz movement drives it, roughly ten times more accurate than standard quartz and COSC-certified.
