Unfortunately, and unlike the 7750, this movement provides no rapid- reset function for the date display via the crown. Instead, the wearer must press a recessed button on the left side of the case to reset the date. This requires a correction stylus or a repurposed tool such as a ballpoint pen or toothpick.
On the other hand, the operation of the crown and push- pieces leaves nothing to be desired. Furthermore, the movement is attractively decorated. Unfortunately, our test watch gained more than 10 second per day, as proven both by the timing machine and the wearing test. Moreover, the small elapsed- minutes hand is not 100 percent vertical in its testing position, but leans a tiny bit toward the left. Fans of retro and sports watches will need to accept this imperfection if they opt for the Heritage 1973. But perhaps they’ll interpret this trivial shortcoming as a beauty mark that reminds them of daring exploits in the glory days of auto racing, when success depended less on technology and engineering and far more on a driver’s passion and charisma.
