The Enicar 167 watch movement features a selfwinding gear made from beryllium bronze and springless pawl wheels with hook-levers. The pawl wheels have two levers and 15 teeth, providing efficiency comparable to a ratchet wheel with 60 teeth, while also offering enhanced durability due to its larger teeth and absence of a click spring. The levers are adjustable to compensate for wear. Additionally, this movement is automatic, incorporates a sweep second hand, and includes a power reserve display of approximately 45 hours. It was primarily used during the period around 1960.
