In 1972, Heuer launched an economy version of the Monaco, references 1533B and G with blue or silver dials. Powered by the Calibre 15 movement, the hour registers were deleted and a tiny seconds hand was positioned at 10 o’clock, with the Monaco model name printed underneath. There is little doubt that the most highly regarded Heuer Monaco is the one with the matte blue dial that Steve McQueen wore in Le Mans. It is ironic that the Monaco was intended to conquer the US market and finally arrived – although with less impact than originally intended – directly in the heart of Hollywood, purely by coincidence.
The growing Monaco product line included both automatic and manual-wind versions. With three sub-registers and no date, the hand-wound models offer a harmonious dial design including a running second hand at 9 o’clock. First shown in the 1970/71 Heuer catalogue, some believe that these models are really undervalued today, compared to their automatic siblings. These watches, with the reference numbers 73633B and G, carried respectively blue and grey dials with contrasting sub registers, and were fitted with Valjoux 7736 movements. As before, the reference numbers were engraved between the lugs and “Tool 033” can be found on the back.
The 73633 cases had similar dimensions to the other models, but the crown was relocated back to the classic position between the fluted chronograph pushers. In the 1972 catalogue, an elegant all-grey dial version was shown.
In 1974, new models of the Monaco were introduced with the reference 74033. The dial design and configuration were similar to the 1133 automatic, with separate registers for hours and minutes and a date window at 6 o’clock, but with no indication for the running seconds. The watch was powered by a Valjoux 7740 manual wind movement, its winding crown located on the right-hand side between the fluted chronograph pushers.
