Chronometer-4 / +6 s/dayCOSC criteria

Automatic SW200-1-based 11½-ligne caliber with small seconds at 6 and quick-set date at 3. Caliber Corner and Grail Watch: Ø25.60mm, 5.60mm high, 31 jewels, 28,800 vph, lift angle 50°, power reserve "at least 38 hours" (Grail Watch: 38 hours), stop-second, hand winding, ball-bearing rotor winding in both directions, Incabloc or Novodiac shock protection, Nivaflex mainspring. Grail Watch: the small-seconds pivot sits 7.6mm from the centre, against 6.4mm on the otherwise similar SW260-1, which suits larger cases. Caliber Corner notes brands casing it without the small seconds (Louis Erard) or without the date (Pitzmann), and a COSC version (Tribus TRI-01). Sellita's own spec sheet could not be read (sellita.ch's caliber pages load through a script), so the power reserve is the minimum figure from those sources, and grade accuracies are Caliber Corner's summary, so only the COSC range is recorded as a number; brands using it often quote 41h, the typical figure for the SW200-1 base.
