Sellita

Sellita's flagship automatic movement and the most widely used Swiss automatic caliber in production today, having filled the supply gap created by ETA's restrictions on third-party sales. A functional clone of the ETA 2824-2, it is dimensionally identical and shares the same parts compatibility. Available in multiple grades from Standard to Top, the SW200-1 powers watches from dozens of Swiss and international brands.
