It is a couple of watch with two dials, the Sort 20 and Sort XX are variations on a theme, one army (with syringe palms, and mint inexperienced lume) and the opposite civilian (with alpha palms and creamy yellow lume). Each watches are cased in metal with 42mm by 14.1mm measurements and with bidirectional metal bezels (and matching lume pips). The Sort 20 and Sort XX each have a brand new self-winding motion, the Calibre 728 for the civilian model and Calibre 7281 for the army model. Every motion has a column wheel, vertical clutch, 5Hz frequency, and flyback performance with 60 hours of energy reserve, plus an inverted in-line lever escapement with a flat silicon steadiness spring for elevated sturdiness, longevity, and magnetic resistance.
