The ETA 251.272 is a high-precision quartz chronograph movement under ETA’s 251 series, sharing core technical features with sibling models like the 251.264/251.274 while aligning with the series’ focus on professional timing. Below is its key information based on series consistency and industry data:
Basic Attributes: It is an analog-display quartz movement produced by ETA, with dimensions consistent with the 251 series standard—approximately 30 mm in diameter and 5 mm in thickness. This size is tailored to accommodate complex chronograph components, ensuring compatibility with cases designed for functional timing watches.
Functional Features:
- Chronograph function: Supports precise short-time measurement, including 1/100-second, 12-hour, 30-minute, and 60-second timing modes, meeting professional needs for accurate elapsed-time tracking.
- Daily timekeeping: Equipped with a 3-hand (hour, minute, small second hand) layout, plus a date display function (typically positioned at the 6 o’clock position), balancing professional performance with everyday practicality.
Accuracy & Technology: Integrates ETA’s PreciDrive technology, a hallmark of the series for minimizing timekeeping errors. Its annual accuracy error is approximately +/- 10 seconds, ensuring long-term stable and reliable timekeeping—far exceeding standard quartz movement precision.
Application Scope: Due to its large size (to fit chronograph mechanisms) and high precision, it is primarily used in mid-to-high-end chronograph watches, such as sports watches for racing/outdoor activities, professional tool watches, or lifestyle timepieces that prioritize both timing functionality and accuracy. It is a go-to option for brands seeking a mature, reliable quartz chronograph solution.
