Powered by the Breitling Caliber 83 thermocompensated SuperQuartz movement — accurate to within a fraction of a degree — this Endurance Pro ref. X83310A71B1S1 offers 1/10th-second chronograph capability alongside hour, minute, second, and date functions. Six jewels and Swiss Made certification speak to the movement's refined construction, while the analog display keeps readability front and center.
The 38mm round case is topped with a scratch-resistant sapphire crystal and secured by a screw-fastened caseback, offering water resistance to 100 meters / 330 feet. A bi-directional rotating bezel expands the watch's functional range, and the non screw-locked crown features dual gaskets for added protection. The black dial carries Arabic numeral markers and luminescent silver-tone hands for easy legibility in varying light conditions.
A white rubber strap with a tang clasp keeps the Endurance Pro comfortable and secure on the wrist, reinforcing its professional sports character. This example is in new condition and ships complete with original box and papers, making it a compelling entry in Breitling's Professional series.
