Measuring 44mm in diameter and 12.5mm thick, this Endurance Pro is built around Breitling's proprietary Breitlight case material — a high-performance composite that keeps the watch notably light on the wrist. A bidirectional rotating bezel features a compass scale, while the non screw-locked crown is sealed with two gaskets for water resistance rated to 100 meters / 330 feet.
The black dial presents a digital layout with Arabic numeral markers and luminescent hands, all protected beneath a scratch-resistant sapphire crystal with glareproof treatment applied to both sides. Driving everything is the Breitling Caliber 82 thermocompensated SuperQuartz movement, offering enhanced accuracy across varying temperatures.
The watch is worn on a black rubber strap secured by a tang-type buckle, and comes complete with its original box and papers. Reference X823101B1B1S1 is presented in unworn condition, making it a compelling choice for anyone seeking a high-specification sport watch from Breitling's Professional series.
