Hand-wound, skeletonised three-hand movement from Miyota's Standard Mechanical (82-size) range, without date. Specs from Caliber Corner: 11½ lignes (26mm), 4.47mm high, 17 jewels, 21,600 vph, 42h power reserve, three central hands, Miyota-claimed accuracy -20 to +40 s/day (measured 10-60 minutes after a full wind; about 40 crown turns fully wind it), available in silver or gilt. Miyota's own product page could not be read on 2026-10-25 (the site was under maintenance), and Caliber Corner notes the 8N33 was dropped from Miyota's online catalogue around February 2021. Hacking is not recorded: Caliber Corner's table says yes but a reader comment there says it doesn't hack. Brands using it (Marloe Coniston, Aevig) case it behind a display caseback rather than as a skeleton dial.
