Breitling's Professional line is where they showcase their impressive technological skills, not just in electronics but also in mechanical watchmaking. Take the Skyracer, for example. This self-winding chronograph is designed to be the most efficient in its category, thanks to the exclusive Caliber 27 mechanism. It lets you easily see the elapsed time in two ways - a 60-minute totalizer for shorter durations and a two-hand counter for longer ones. Plus, the slide-rule feature makes calculations a breeze. And let's not forget the aviation-inspired design, complete with symbols from the Ground Air Visual Signal Code on the caseback. Check it out with REF. A2736223/C712.
