Hanhart is harking back to its close association with motor racing in the 1960s and 1970s with the launch of the Racemaster GT, the Racemaster GTM and the Racemaster GTF. With their sporty, technology-inspired design, these models are the first produced to feature watch cases made from HDSPro® steel, which is 100 times more scratch-resistant than conventional stainless steel.
