Calibre 13 Phi description
Self-winding movement with chronograph, based on the ETA 7750 with Top finishing. The base movement has undergone several modifications in a small workshop from La Chaux-de-Fonds, such as the removal of the date mechanism and the relocation of the minutes subsidiary dial from 12 o'clock to 3 o'clock thanks to a proprietary module, and an upgrade to blue screws. The Calibre 13 Phi received additional modifications on the back side to add the fly-back function.
