Sellita's ETA 2824-2 counterpart: same 11½-ligne layout and dimensions, built to the 2824-2 design after the patents expired. Sellita technical documentation (02.09.2024): case fitting Ø25.60mm (overall Ø26.00mm), 4.60mm high, 26 jewels, 28,800 vph, power reserve minimum 38h / typical 41h, lift angle 50°, Incabloc, stop-second, ball-bearing rotor, quick date. Versions: "SW200-1 a" has the date, "SW200-1 b" is a true no-date (two crown positions); in the 2026-27 catalogue both list a typical 41h power reserve, so the letter marks the date/no-date version, not a power-reserve revision. Older documents quoted 38h, the minimum figure, which is why 38h still circulates. Grades: the current technical documentation lists Elaboré, Top and Chronomètre only; Caliber Corner and older material also list a "Standard" grade (2 positions, ±12 s/day, max. 30 s/day) and use the names Special/Premium for Elaboré/Top. Succeeded by the SW200-2 Power+ (65h), which Sellita sells alongside it.
