Crafted for active use, the Endurance Pro wears its 44mm round case in Breitlight®, a high-tech polymer chosen for its notable durability and low weight. The black dial is read through a sapphire crystal with double anti-reflective coating, and luminescent silver-tone hands work alongside Arabic numeral markers to keep time legible across varying light conditions. A tang clasp secures the black rubber strap firmly to the wrist.
Powering the watch is a Thermocompensated SuperQuartz™ movement, which delivers accuracy ten times greater than a conventional quartz caliber. The dial layout supports a full suite of functions — chronograph, date, hours, minutes, and seconds — making it a capable companion for timing-focused activities. Water resistance is rated to 100 meters / 330 feet, adding confidence in demanding conditions.
This reference X82310E51B1S2 is presented in unworn condition and carries its 2025 production date, with the original box and papers included. It bears the Swiss Made designation and leaves the factory without any aftermarket customization.
