Sellita introduced their SW 200 as a direct replacement for the ETA 2824. It uses most of the same components.
The SW 200 was improved, becoming the SW 200-1, in 2008 to improve reliability. Three gears were changed with new tooth profiles.
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.
