Hand-wound version of the automatic SW288-1 (see sellita-sw288-1): no rotor, with a large moon-phase disc coaxial with the hands that takes up most of the upper dial, and a date window at 6 (Grail Watch; Farer's description of the "SW288-1 M a" also puts the quick-set date at 6). Sellita technical documentation (SW 288-1 M, version 01, 26.08.2021): case fitting Ø25.60mm (11½ lignes), 4.40mm high, 18 jewels, 28,800 vph, running time minimum 42h / typical 45h (typical recorded), lift angle 50°, Incabloc shock protection. The documentation as read does not list factory grades, so none are recorded; Farer uses it in Elaboré grade. Stop-seconds per Grail Watch and Farer. Grail Watch lists 19 jewels and 42h (the documented minimum); Sellita's 18 jewels and 45h typical are used (Farer gives the same). Farer names an "a" execution; the layout above is the one Grail Watch and Farer describe. Family set to "Sellita SW210", the hand-wound line, as for the SW200-2 M. sellita.ch was in maintenance on 2026-10-21, so the documentation was read from the copy on ManualsLib.
