Certina Certina 19-10

The Certina 19-10 is a manual-winding movement manufactured by Certina. It features 15 jewels, Incabloc shock protection, and a pin-lever escapement. The movement drives the train and hand gear separately from the barrel, using an eccentric minute wheel for the train and a friction-coupled cannon pinion for the hand gear. This design achieves a low profile but demands high precision due to the coupling between the second and minute hands. Production ceased around 1975.
