The Enicar 1165 watch movement, manufactured from 1956 to 1963, features a pin-lever escapement with ruby pins. It is a detached manual wind movement with a ratchet on the dial side and a crown mechanism with a rocker bar. Both the base movement and automatic module are pillar designs, allowing for easy access to most lubrication spots for partial disassembly maintenance. In terms of dating, modifications such as varied rotor shapes are not helpful due to the short manufacturing period and missing records. The differences between the 57/22 and 58/21 variations of this movement are not known. Additionally, the movement offers automatic functionality and a date function that can be set by +/-24 hours.
