The Sellita SW 200 is an automatic movement from Sellita based on the ETA 2824-2.

History

Sellita introduced their SW 200 as a direct replacement for the ETA 2824. It uses most of the same components. Although many sources claim introduction as early as 2003, there is no evidence that the SW200 name existed prior to 2007. Sellita's own website only shows SW200 as of 2008.

The SW 200 was improved, becoming the SW 200-1, in 2008 to improve reliability. Three gears were changed with new tooth profiles.

Variants

SW 200 is a mechanical movement with self-winding, ball-bearing rotor, hacking seconds, power reserve: ca. 38 hours. The base movement, SW 220-1, measures 11.5 ligne, has an automatic rotor, and a day and date wheel. Without the day wheel, this becomes SW 200-1, and hand-winding versions with and without date are SW 215-1 and SW 210-1, respectively. Cal. SW 240-1 has an outer full-text date wheel and is thus wider at 13 ligne. Finally, two small seconds variants are produced: SW 260-1 has a hunter arrangement with seconds at 6:00, while SW 290-1 has lepine seconds at 9:00.
