The caliber 70 ist another very nice 10 1/2 ligne movement from the swiss Fabrique d’Horologerie de Fontainemelon. As other FHF movements of that epoch, it pleases with its well arranged layout, with its good manufacturing with bevelled angles, clean engravings (on the dial-side, too) and grindings. The nickel screw balance is of course beared between two Incablock shock protection bearings and has got a long regulator arm.
