The Heritage Chrono, featuring a cool grey dial with pops of blue, debuted at BaselWorld 2013 alongside the previous 70330N models. Like its predecessors, this watch runs on an ETA caliber 2892 with a module for the chronograph functions. In 2018, the original silver dial model (70330B-0001) was swapped for the new 70330B-0004, which comes with both a bracelet and a strap. The -0003 model, on the other hand, is solely for the bracelet, while the -0004 is for the NATO strap.
