The "see-through caseback" has been one of the important aethestic features for a mechanical watch.
The precise yet romantic motion of the rotor fascinates not only watch lovers but also ordinary watch wearers.
This time, the surface finish of the rotor for the Cal.8215 and Cal.8205 have been upgraded to better suit see-through caseback designs.
