The present example is the silver-dial version of the Dato 45, featuring a date window at 9 o’clock and a single white minute-totaliser at 3 o’clock. The result is arguably one of the quirkiest and most distinctive designs in the entire Carrera lineup. It also represents the pinnacle of Jack Heuer’s minimalist, legibility-first design ethos—so minimal, in fact, that it omits even a running seconds hand. As Heuer declared in a 1969 advertisement, this watch was made “for the businessman who needs a chronograph but can never remember the date.”
