Calibre by Breitling
Self-winding manufacture movement, column-wheel chronograph with a power reserve of 70 hours.
First used in the model Chronomat B01.
In order to simplify the production and use, Breitling has provided the movement with completely new features. These include, for example, a patented self-centering system, a heart lever for the zero-position and an exclusive regulator mechanism, which allows to adapt the adjustment quickly and easily to the watch wearer.
Since this movement has the same diameter as the calibre ETA 7750, which Breitling has frequently used until now, in the future it will be possible to use it also in models that were previously equipped with the ETA movement.
Breitling supplies the same architecture to Tudor for their MT5813 movement.
