Buren and Duipuis Depraz

See https://monochrome-watches.com/calibre-11-history-iconic-movement-and-its-evolution-in-depth/ for details.

Buren pioneered micro rotors. Dupuis at Depraz want to combine an automatic movement with a chronograph movement. Hamilton (who owned Buren at this point), Heuer and Breitling committed to use the movement. Cal 11 was produced, which iterated over time to Cal 12, Cal 13 and Cal 14. Valjoux them took the Cal 14. Valjoux then took Cal 14 made it manual wind and sold it as Caliber 7740. The basic chronograph design then was the basis of the Valjoux like of 77XX movements.

If the crown is on the left, it's cal 11, 12, 13 or 14.
