The ETA 251.471 is a compact quartz movement tailored for slim, functional wristwatches, belonging to ETA’s mid-range practical quartz lineup. Below is its core information based on technical specifications and industry application data:
Basic Attributes: It is an analog-display quartz movement, typically powered by a Renata 371 (SR920SW) button cell battery. Under normal daily use, the battery life can reach 36-48 months, ensuring long-term stable operation with minimal maintenance.
Dimension Specifications: The movement has a compact footprint, with a diameter of approximately 15.1 mm and a core thickness of about 2.5 mm. Its slim size makes it compatible with thin watch cases, suitable for both men’s and women’s daily-wear timepieces that prioritize a sleek profile.
Functional Features: Adopts a 3-hand (hour, minute, second) basic timekeeping structure and is equipped with a date display function (date window usually positioned at the 3 o’clock position). This combination fully meets daily time-checking and date-tracking needs, balancing practicality and simplicity.
Internal Configuration: Fitted with 5 synthetic jewel bearings (commonly ruby). These high-hardness bearings reduce friction between internal rotating components, effectively enhancing the movement’s operational precision, stability, and service life—critical for maintaining reliable performance in frequent use.
Application Scope: With its reliable performance, moderate cost, and compact size, the 251.471 is widely used in mid-range casual watches, business-style daily-wear timepieces, and entry-level luxury brand accessories. It is particularly favored for watch designs that require basic functions while keeping the overall case thin and lightweight.
