The PRIMUS Pilot, which is a contemporarytake on legendary pilot'schronographs,is the idealwatch for precision timekeeping in the air.Reminders ofHanhart's tradition aremade clearly recognisable: one of the brand's distinctive features,the red button, has been a distinguishing characteristic of Hanhart chronographs since 1939 and was previously intended to prevent pilots fromunintentionally resetting the stop time. Because pilots previously operated the crown oftheir wristwatch whilst wearing gloves, it had tobe as large and slip-proof as possible, as today on the PRIMUS Pilot.
