Three-hand, no-date solar quartz that uses a ring-shaped solar cell instead of a cell behind the dial, so it can be used with opaque metal dials (Islander describes the collector as part of the rehaut). Smaller sibling of the Φ36.2mm Miyota 2170; the two are not interchangeable, so they are separate families. Factory spec sheet: size Φ30.2mm, height 3.78mm (5.98mm including the movement holder), accuracy ±20 s/month, running time 4 months on a full charge, battery consumption minimised by pulling out the stem; stem 065-468. Miyota's instruction manual names the rechargeable cell as MT621 and shows two crown positions (normal and time-setting). Islander adds an end-of-life indicator: the seconds hand moves in 2-second steps when the charge is low. Jewel count, hacking and country of manufacture are not stated by Miyota. Miyota's product page marks the 2070 as discontinued (checked 2026-10-21). Tier "entry" per the guide's basic Miyota quartz row.
