The ETA 256.461 is a reliable compact quartz movement under ETA’s 256 series, designed for entry-to-mid-range wristwatches that prioritize daily practicality and slimness. Below is its core information based on series characteristics and industry application data:
Basic Attributes: Classified as an analog-display quartz movement, it is typically powered by a Renata R371 (SR920SW) button cell battery. Under normal daily use, the battery life can reach 36-48 months, ensuring long-term low-maintenance operation.
Dimension Specifications: It features a compact size with a diameter of approximately 15.1 mm and a core thickness of about 2.5 mm. This slim and small profile makes it compatible with thin, lightweight watch cases, suitable for both men’s casual daily-wear watches and women’s delicate timepieces.
Functional Features: Adopts a 3-hand (hour, minute, second) basic timekeeping structure and is equipped with a date display function (the date window is usually positioned at the 3 o’clock position). This combination focuses on simplicity, fully meeting daily needs for time-checking and date-tracking without redundant complex functions.
Internal Configuration: Fitted with 5 synthetic jewel bearings (commonly ruby bearings). These high-hardness components reduce friction between internal rotating parts, effectively enhancing the movement’s operational stability, extending its service life, and maintaining standard quartz precision (typical daily error within +/- 15 seconds).
Application Scope: With its stable performance, cost-effectiveness, and compact size, the 256.461 is widely used in entry-level casual watches, budget-friendly business timepieces, and mass-produced fashion watches. It is a mainstream choice for brands seeking to balance basic functionality, slim design, and affordability.
