The ETA 2750 is a compact manual-wind mechanical watch movement from the Swiss manufacturer ETA, produced between 1969 and 1982. Part of the pre-2800 family, it shares components with earlier 2500/2600 series and later models, emphasizing reliability in slim designs. Over 6 million units were made, powering time-only watches from brands like Favre-Leuba.
Key Specifications
Size and Beat Rate: 11.5 ligne diameter, 21,600 beats per hour (6 beats/second) for smooth sweeping seconds.
Functions: Primarily time-only (hours, minutes, seconds); variants like ETA 2752 add date quickset via crown manipulation between 20-24 o’clock.
Jewels and Height: Typically 17 jewels, slim profile around 3.45mm thick, ideal for dress watches.
Family Variants
The 2750 anchors a versatile lineup at 21,600 bph:
ETA 2750: Base time-only, hand-winding.
ETA 2752: Date complication.
Higher-speed siblings like ETA 2751 (28,800/36,000 bph) for enhanced precision.
Day-date options (e.g., 2758/2759) expand utility, with quickset features in select models.
Historical Context
Introduced in the late 1960s amid quartz threats, the 2750 bridged ETA’s 2500-era workhorses to modern 2800/2824 staples. Its shared parts (e.g., cannon pinion, minute bridge) reduced costs, aiding widespread adoption in vintage Swiss watches. Production ended in 1982 as automatics dominated.
