In the realm of high-performance sport watches, the Endurance Pro encapsulates the ethos of the athlete-and-everyday-wearer alike: bold, lightweight and tech-forward. With its 44 mm diameter case crafted from Breitling’s proprietary Breitlight® material — a polymer composite that is 3.3 times lighter than titanium and 5.8 times lighter than stainless steel — the watch delivers extraordinary wearability. The case measures 12.5 mm thick, and wraps a solid athletic silhouette with the lug-to-lug around 52.4 mm.

On the dial side, you have a matte black background with subtle blue accents, bold Arabic numerals, a date window between 4 and 5 o’clock, and a chronograph layout with 30-minute and 1/10th-second counters — all under glare-proofed sapphire crystal. The bidirectional rotating bezel features a compass or pulsometer scale, underscoring the watch’s “go-anywhere” athletic character.

At its core sits the in-house caliber B82 — a thermo-compensated SuperQuartz™ movement, COSC-certified, offering accuracy far beyond typical quartz and a battery life of approximately 4 years in many listings. Functionally, the watch gives you hours, minutes, small seconds, chronograph (1/10th-sec + 30 mins) and date. It also boasts water resistance to 10 bar (≈100 m).

From a wearability and utility standpoint, the Endurance Pro walks a compelling line: the large diameter and distinctive case material give it presence, yet the feather-light weight ensures it doesn’t feel burdensome on the wrist. The rubber Diver Pro strap (often in blue or other colors) reinforces the sport-lifestyle intent.
