The Monaco wristwatch was one of the first automatic chronographs offered in the market. In 1972, Heuer released the manual wind reference 73633, which retained the uniquely shaped case, however resembled a classic chronograph with the winding and setting stem on the right-side of the case. The reference was produced with three dial styles, blue with white registers, grey with grey registers and like the present watch grey with black registers.

The watch has a dynamic appeal with its two-tone dial with red inserts and luminous dots, as well as the red chronograph hands. Offered in exceptional condition, the watch appears to have been unworn, or very little worn since it was first manufactured. The case is sharp with well-defined lines and facets. The Monaco is a wonderful expression of the 1960s and 1970s when freedom, extravagance and daring to be different where en vogue.
