The ETA 251.274 is a high-performance quartz chronograph movement belonging to ETA’s 251 series, sharing technical roots with the 251.264 but potentially optimized for specific use cases. Below is its core information based on series consistency and industry data:
Basic Attributes: Classified as a quartz movement with analog display, it is manufactured by ETA. It has a diameter of approximately 30 mm and a thickness of around 5 mm—consistent with the 251 series’ size standard, ensuring compatibility with cases designed for complex chronograph functions.
Functional Features:
- Retains the core chronograph function: Supports 1/100-second, 12-hour, 30-minute, and 60-second timing, meeting precise short-time measurement needs.
- Standard timekeeping: Equipped with 3-hand (hour, minute, small second hand) display, plus a date display function (typically at the 6 o’clock position), balancing professional timing and daily practicality.
Accuracy & Technology: Adopts ETA’s PreciDrive technology, which minimizes timekeeping errors. Its annual error is approximately +/- 10 seconds, maintaining the high precision characteristic of the 251 series and ensuring long-term stable performance.
Application Scope: Due to its large size (to accommodate chronograph components) and complex functions, it is mainly used in mid-to-high-end chronograph watches—such as sports watches for outdoor/racing scenarios, or professional tool watches that require precise timing. It is also a common choice for brands seeking reliable, high-precision quartz chronograph solutions.
