There's a reason we call our Endurance Pro the ultimate athleisure watch. It's because it can make the rounds from class to work to the gym without missing a beat. (Sound like a soon to be graduate you know?) Powered the Breitling Caliber 82, a COSC certified SuperQuartz movement, the Endurance Pro (Princeton University Edition) is the Ivy League of precision. The nostalgic Princeton Orange strap and university shield on the dial and caseback make this a gift to wear and treasure, long after this years grads have turned the tassel. Designed for men and women whose active lives blend a professional mindset with a sporty lifestyle, the Endurance Pro is equal 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 touch that is warmer than metal and a slightly textured effect accentuating the originality of the design. Exclusive to Breitling, it is 100% Swiss made.
