Introduction to ETA Movements and Their Popularity
For watch aficionados, ETA movements are among the most recognized names in the industry. As one of the most widely used and reliable watch movements today, ETA offers stability, precision, and a broad range of models that cater to different watch categories.
This article dives into the classification of ETA movement grades, helping you understand the craftsmanship and quality behind each level.

Detailed ETA Movement Grade Classification
Grade 1 (Basic Level)
The mainplate is untreated and unpolished. The escapement components are made from ordinary steel and copper, suitable for entry-level watches.
Grade 2
The movement is polished, but the escapement still uses basic steel and copper materials, offering slightly improved performance.
Grade 3
Movement parts are polished and electroplated for a brighter finish. Escapement components are made from alloy materials, enhancing accuracy and temperature resistance.
Grade 4
Similar to Grade 3, but includes a fine adjustment mechanism (regulator) for more precise timing.
Grade 5
The mainplate features stricter polishing and finishing. It has a unique caliber number, uses premium alloy escapement components, includes the regulator, and is chronometer-certified, with engraving indicating five-position adjustments.
Grade 6
Building on Grade 5 standards, Grade 6 adds chamfered and mirror-polished escapement wheels, pallet forks, and regulator parts. It uses spherical jewel settings, chamfered gears with textured finishes, and mirror-finished screws. Automatic versions use gold rotor plates, reaching high-end watchmaking standards.

Grade 7
Movements that meet the Geneva Seal requirements, fully developed, designed, and manufactured in-house by the brand, representing advanced horological craftsmanship.
Grade 8 (Top-tier Handcrafted Movements)
Crafted by master watchmakers for competitions and certified with the Geneva Seal. Every step—from design, machining, polishing, testing to assembly—is completed by individual artisans or small ateliers. These movements often feature super-complicated functions and represent the pinnacle of watchmaking art and legacy.
