The Cal.11 has been considered as the earliest self-winding mechanical movement in the world which was developed by several watch brands including Breitling, TAG Heuer and so on. Referring to the most popular fake watch equipped with the legendary movement, it must be the TAG Heuer Monaco.
The square TAG Heuer Monaco copy with blue dial was manufactured in August of 1969 which was especially designed for Formula 1. But why was it so popular all over the world till now? It was because of Steve McQueen, the legendary film star. He wore the Monaco in the movie “Le Mans”, causing a heat all over the world.
TAG Heuer imitation with steel case was also the world’s first automatic chronograph with square case which was also water resistant. Till now, the color-matching and movement have been changed for many times, however, it still maintains the original racing style, and the movement it equips is always developed on basis of the original Cal.11.
