Heuer “Monaco”, Ref. 1533, Cal. 15
The Cal. 15 movement was a low-cost version of the Cal. 11 movement introduced in 1972 and offered across the “Monaco”, “Autavia” and “Carrera” ranges, alongside the Cal. 12 variants.
The Cal. 15 watches have a 30-minute counter at 3 o’clock and sweeping seconds at 10 o’clock on the dial where the 12-hour counter would normally be on a Cal. 11 and Cal. 12.
Heuer took the revised movement layout as an opportunity to offer a totally new look for the Cal. 15 watches, and as a result some collectors prefer the look of the Cal. 15 models to the “standard” Cal. 11 or Cal. 12 versions.
The Cal. 15 with grey dial is perhaps the most special “Monaco” production model, with a wonderful dial that is a “golden silver” colour.
