Overview

The ETA 2639 is a Swiss-made automatic movement known for its practical day-date layout, central seconds, and durable construction suited to daily wear watches of its era. It belongs to the broader 26xx family, sharing many components and architecture traits with related calibers.
Key technical specifications

Automatic winding with central sweep seconds

Day and date display with quickset function

Diameter around 29.0 mm (13’’’ ligne size)

Height around 4.9–5.0 mm

Beat rate 21,600 vibrations per hour (3 Hz)

Power reserve typically around 40–42 hours

Jewel counts commonly 17, 21 or 25 jewels depending on execution

Design and construction

The architecture favors serviceability, with a conventional automatic module driving a centrally mounted seconds hand and a straightforward calendar mechanism. Bridges and plates typically follow the clean, functional finish expected from mid-range Swiss ébauches of the period rather than elaborate decoration.
Calendar and user features

Hand-winding capability complements automatic winding for watches that are not worn daily

Practical watchmaking notes

Watchmakers often appreciate the ETA 2639 for its parts availability (shared with other 26xx calibers) and predictable behavior on the timing machine. Regulation to acceptable daily rates is usually straightforward, aided by the 3 Hz beat rate which balances shock resistance and energy consumption. For collectors and technicians, it represents a dependable, easily serviced vintage automatic movement rather than a high-complication or haute horlogerie piece.
