"Power+" successor to the SW200-1, unveiled by Sellita in February 2026 and produced alongside it. Same dimensions and layout as the SW200-1 (drop-in for case makers) but most parts are new and not interchangeable: redesigned barrel and mainspring, optimised gear train, improved automatic winding, balance inertia cut from 16 to 8 mg·cm², new regulator and new Incabloc shock protection. Factory sheet: power reserve minimum 60h, typical 65h; overall diameter 26.00mm, casing diameter 25.60mm (11 1/2 lignes); lift angle 50°; stop-second; quick-set date; ball-bearing rotor. The datasheet lists Elaboré, Top and Chronomètre executions only (no Standard grade); the grade ranges above are the datasheet's mean rate ± tolerance. Family kept as "Sellita SW200" because it is a dimensional drop-in for the SW200-1.
