Day-date version of the 8215 (same base; Caliber Corner calls them "virtually the same movement"). Factory spec from Miyota's combined 8215/8205 sheet and product page: 11½ lignes (Φ26.00mm), 5.67mm high, 21 jewels, 21,600 vph, running time approximately 42 hours, accuracy -20 to +40 s/day, posture difference under 50 s, lift angle 49°, automatic and hand winding, quick date setting, stop second device. Miyota's listed calendar variations put the day and date at 3 o'clock; Caliber Corner notes watches with the day/date at 3:00 or 6:00. Hacking: Miyota's current page and manual describe a stop-second device, but Caliber Corner reports Miyota only added it to the 82 family around 2018-2019, so older 8205s may not hack. A gilt version is available.
