Day-date version of Miyota's standard 2115 three-hand quartz, sharing its spec sheet and dimensions: 10½ lignes (Φ23.7mm), 4.15mm high, accuracy ±20 s/month, SR626SW (377) battery, about 3 years' battery life; pulling out the stem stops the seconds hand and minimises battery consumption. Calendar variations put the day and date together at 3 o'clock on most versions (others split day at 12 or 3 and date at 6). Miyota's site was down for maintenance when this file was written (2026-10-25), so the figures are from Caliber Corner's 2105 page, which match the shared 2115/2105 Miyota spec sheet cited in miyota-2115.yaml; 0 jewels, 32,768 Hz and Japanese manufacture are from Caliber Corner. Grouped in the Miyota 2115 family because it is the same base caliber with a day wheel added.
