The ETA 2764 is a manual-wind mechanical watch movement from ETA’s 2700/2770 family, renowned for its reliability in mid-20th-century timepieces. Produced between 1971 and 1978, it features a high-beat rate of 28,800 vibrations per hour (A/h), offering smooth seconds-hand sweep and precision timing. This 11.5 ligne (25.6 mm diameter) caliber measures 5.2 mm thick with 17 jewels, providing about 45 hours of power reserve.
Key Specifications
Beat rate: 28,800 A/h for enhanced accuracy over standard 21,600 A/h siblings.

Historical Context
Introduced amid ETA’s mass production era (over 25 million 2770-family units made 1969-1982), the 2764 powered affordable dress and sports watches from brands like Certina, Longines, and Omega variants. Its manual winding appeals to purists favoring direct barrel energy transfer. Production ceased in the late 1970s amid quartz competition, but spares remain available via specialists.
