ETA 2671

ETA · Automatic · Found in 182 watches

Known interchangeably as the 2671 or Cal. 2671, this automatic movement from ETA serves as a compact and functional engine for various timepieces. As a self-winding mechanism, it harnesses the natural motion of the wearer's wrist to power its intricate components, eliminating the need for manual winding when worn regularly. The Cal. 2671 operates with 25 jewels, strategically placed at points of friction within the movement to reduce wear and enhance the longevity and stability of its operation. Its balance wheel oscillates at a frequency of 28,800 vibrations per hour (vph), equivalent to 4 Hz. This high frequency contributes to the movement's accuracy and results in a smooth, sweeping motion of the seconds hand, characteristic of many modern mechanical watches. Once fully wound, the movement offers a power reserve of 38 hours, meaning a watch powered by the 2671 can continue to run for over a day and a half when not being worn, before requiring winding or wear to restart. Measuring a diameter of 17.2 mm and a height of 6.4 mm, the ETA 2671 is characterized by its relatively small dimensions. This compact size makes it particularly suitable for watches with smaller case diameters, often found in ladies' collections or more discreet men's timepieces. The movement's lift angle is specified at 52°. In terms of functionality, the 2671 provides the essential complications of hours, minutes, and seconds, allowing for precise time telling.
