Seiko Epson Y121E
QuartzThree-hand analog quartz movement with central hours, minutes and seconds and no calendar. The historical Epson Y121E document gives casing dimensions of 15.3 × 17.8 mm, a height of 2.99 mm and a two-year battery life. Uses SR626SW. The current official download at the old y121e filename describes Y121F, a different revision, and is not treated as the exact E technical specification.
