The ETA 255.441 is a practical quartz movement belonging to ETA’s 255 series, designed for entry-to-mid-range wristwatches that prioritize basic functionality and reliability. Below is its core information based on series specifications and industry application data:
Basic Attributes: It is an analog-display quartz movement, typically powered by a common button cell battery (often Renata R371/SR920SW or equivalent). Under normal daily use, the battery life can reach 36-48 months, ensuring low maintenance for daily wear.
Dimension Specifications: The movement features a compact footprint, with a diameter of approximately 15.1 mm and a core thickness of about 2.5 mm. Its slim and small size makes it compatible with thin, lightweight watch cases, suitable for both men’s casual 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 fully meets daily needs for time-checking and date-tracking, focusing on simplicity and practicality 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 improving the movement’s operational stability, extending its service life, and maintaining basic timekeeping precision (typical daily error within +/- 15 seconds, meeting standard quartz movement performance).
Application Scope: With its stable performance, affordable cost, and compact size, the 255.441 is widely used in entry-level casual watches, daily business timepieces, and budget-friendly fashion watches. It is a mainstream choice for brands aiming to balance functionality and cost-effectiveness in mass-produced wristwatches.
