Breitling Watch Endurance Pro 44 X82310281B1S2. Designed to be both a lightweight timepiece for athletes and a casual, everyday sports chronograph, the Endurance Pro perfectly blends innovative technology with a vibrant design to produce the ultimate athleisure watch. Designed for men and women whose active lives combine a professional mindset with a sporty lifestyle, the Endurance Pro is up to the challenges of a rigorous workout, but fashionable enough for everyday wear. The Endurance Pro features an ultralight Breitlight case, a robust material 3.3 times lighter than titanium and 5.8 times lighter than stainless steel. Nonmagnetic, thermally stable and hypoallergenic, Breitlight is highly resistant to scratches, traction and corrosion. It also has a feel that is warmer than metal and a slightly textured effect, accentuating the originality of the design. Exclusive to Breitling, the material is 100percent Swissmade. In 44 mm or 38 mm, the Endurance Pro is available to athletes with a multitude of colourful dials and rubber straps all fitting a Breitlight tangtype buckle. The two sizes are respectively powered by Breitlings Caliber 82 and 83, both COSC certified SuperQuartz chronographs delivering exceptional precision.
