Small-seconds member of Sellita's thin SW300 family, the counterpart of the ETA 2895-2. Sellita 2026-27 catalogue: 11½ lignes, Ø25.60mm, 4.35mm high, hours and minutes with small seconds at 6 (pivot 5.70mm from centre), date with quick setting, ball-bearing self-winding, stop-second, 28,800 vph, 31 jewels, typical power reserve 56h. Grail Watch dates Sellita's internal documents to 2014 with first public mentions in 2016, and reports that a new barrel and mainspring in 2021 raised the power reserve from 42h to 56h, so earlier watches may quote 42h; its 3.60mm height is the SW300-1's and is not used. Sellita's technical sheet for this caliber was not available at its usual address, so factory grade accuracies are left out (watch brands sell it in Elaboré grade).
