NOTES: The Heuer MONACO was introduced in 1969 in honor of the Monaco Grand Prix race. The Monaco was revolutionary for being the first automatic chronograph with the Caliber 11 and the first square-cased as well. The Hollywood film star Steve McQueen used the watch to accessorize his character in the 1971 film Le Mans and the use of film stills has made the watch synonymous with McQueen. The Heuer Monaco was discontinued in the mid-1970s and redesigned in 1998 and finally relaunched in 2003 corresponding to McQueen’s heritage and lifestyle growing in popularity.
In the reference 1533G, the ‘G’ stands for grey although the dial looks silver is was references as such. This is one of the rarer versions of the MONACO with the Caliber 15 movement and has the seconds counter at 10 o’clock instead of the 12-hour register.
The 1960’s saw the race towards the development of the first automatic chronograph movement. Two groups were in contention for this feat: Movado/Zenith versus Heuer/Breitling/Hamilton/Dubois Depraz. The Caliber 11 was released just ahead of its competitor in March 1969 and became the first iconic automatic chronograph in the world.
The amalgamations that lead to its success therefore benefited from the same caliber fitted into Breitling, Heuer-Leonidas and Hamilton-Buren. This caliber became the base workhorse for the next 40 years to follow including its successor the Caliber 11-I and the Caliber 12.
In 1972, Heuer and Breitling modified the Caliber 12 movement so that it was offered as the Caliber 15 movement, a more affordable version of their automatic chronograph. The most apparent difference between the two movements is that the Caliber 12 movement has a 12-hour and a 30-minute chronograph register, whereas the Caliber 15 movement has only the 30-minute register and a running seconds counter a 10 o’clock.
There were also some technical modifications to the balance wheel, shock protection and regulation. Retail prices were able to be reduced by $5 to $20 (about 10%) depending on the models, which was a considerable amount at the time when the Carrera retailed for below $200.
