The. Breitling Endurance Pro described as an athleisure watch, this should, like your favorite workout clothes, be compatible with workouts and lounging alike. The COSC-certified Super quartz movement powers this large chronograph, which is housed in a lightweight titanium case for ease of wear, whether on the run or sitting in traffic. A rather large case, this watch measures 44mm across, which is certainly helpful if you’re in motion. The black dial has colorful red highlights, which greatly increase legibility, as well as red details on the crown. The watch comes on a rubber strap, and though you might instinctively want in on a bracelet, it’s probably best this way if you plan to actually take it to the gym with you.
