A quintessential regatta chronograph, the Skipper 15640 translates Heuer’s racing DNA to the water with a distinctive 15-minute countdown register that “jumps” every 30 seconds—engineered by modifying the Calibre 15. The crown sits at 9 o’clock (a hallmark of the Buren-based automatic), and the rotating bezel frames a high-contrast dial with the three color segments on the 15-minute sub-dial used to track yacht-race starts. Heuer did not make Skipper-specific cases; instead, it housed Skippers in Autavia and Carrera cases.
