History and Development
Introduced around 2004-2006, the ETA 2826-2 evolved from the base 2824-2 by adding a semi-instantaneous big date at 3 o’clock, enhancing readability for modern designs. It features hacking seconds for precise time-setting and Incabloc shock protection. Production continues despite Swatch Group export limits since 2020, pushing brands toward alternatives like Sellita SW330.
Features and Reliability
This self-winding caliber offers central hours, minutes, seconds, and magnified big date, with a ball-bearing rotor for efficient winding. Known as a “workhorse,” it powers brands like Tissot, Hamilton, and Oris, balancing affordability with COSC certification potential. Service intervals reach 5-8 years due to robust construction.
