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 ultra-light Breitlight® case, a robust material 3.3 times lighter than titanium and 5.8 times lighter than stainless steel. Non-magnetic, 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 100-percent Swiss-made. In 44 mm, this Endurance Pro features a navy blue rubber strap with a Breitlight® tang-type buckle, and is powered by Breitling’s Caliber 82, a COSC-certified SuperQuartz chronograph that delivers exceptional precision.
