In 1966, Heuer released the reference 3147 “Dato,” the first Carrera to feature a date function. The initial execution had symmetrical double registers, similar to the Carrera 45, with the date window positioned at 12 o’clock—earning it the nickname “Dato 12.” This is followed quickly by the second execution of the 3147: the Dato 45.

The reference 3147N here is the rarer black dial variant of the Dato 45. It features a date window at 9 o’clock and a single white register (the minute totaliser) at 3 o’clock. The result is arguably one of the quirkiest and most distinctive designs in the Carrera lineup.
