Multi-function member of Miyota's "Premium Mechanical" 9100 series (siblings 9100, 9122, 9132), laid out like a 3-6-9 chronograph but without chronograph functions: central hours, minutes and seconds, date window at 4:30, pointer day-of-week subdial at 9, pointer month subdial at 3 and a 24-hour (day/night) indicator at 6 that does not show a second time zone. The schema has no "month" or day/night function, so those are only recorded here. Specs are from Caliber Corner (13 1/2 lignes, 30.2mm, 5.52mm high, 26 jewels, 28,800 vph, about 40h power reserve, hacking, hand winding, Parashock), which quotes Miyota's -10 to +30 s/day; they match the official figures recorded for the 9122 in the same series (see miyota-9122). Miyota's own site was down for maintenance on 2026-10-25, so the official 9120 page could not be checked.
