Automatic, cam-operated two-pusher chronograph; Sellita calls it the "tricompax" version of the SW500, with the same casing dimensions and hands. Sellita technical documentation (version 05, 29.03.2023): case fitting Ø30.00mm (13¼ lignes), overall Ø30.40mm, 7.90mm high, 27 jewels, 28,800 vph, power reserve minimum 56h / typical 62h, lift angle 50°, ball-bearing rotor, stop-second. The base SW510 a (recorded here) has small seconds at 9, centre 60-second chronograph hand, 30-minute counter at 3, 12-hour counter at 6 and a date window with quick setting. The 2026-2027 catalogue also lists the SW510 b (same layout, no date), the horizontal-bicompax SW510 BH a/b/c (no 12-hour counter; b without date, c without small seconds), monopusher MP/MPC executions, the SW511 with a 15-minute counter, and hand-wound "M" versions (see sellita-sw510-m).
