New Miyota automatic with about 80 hours of power reserve "at full wind", announced in October 2026 and supplied first to a few brands (KUOE says it is the only Japanese brand with early access, in its Royal Smith 90-006 80hrs). Miyota had published no spec page or sheet for it on 2026-10-31 (miyotamovement.com/product/9085/ returned 404), so this file holds only what KUOE states: automatic with hand winding and hacking, about 80h, accuracy -10 to +30 s/day (KUOE's spec table, the same tolerance Miyota gives for the 90xx calibers), and a date at 3 in KUOE's photos. KUOE compares it with the 42h Cal. 9015 ("about twice" the reserve), but whether it shares the 90xx base, frequency, jewel count or height is not confirmed, so it is kept as its own family until Miyota's sheet appears.
