This item is considered junk due to untested functionality after the battery died. Brand and Series: Seiko Dolce. Movement: Features a high-precision quartz movement; the early Dolce series pioneered high-accuracy quartz movements. Design: Characterized by a slim case and a clean, uncluttered dial, making it a suitable timepiece for formal occasions. Model Number: The specific model number (reference number) can be found on the watch's case back, indicated by an 8-digit number. The first four digits represent the "caliber number." Search results show examples of similar models, such as "5E31-6B90" and "9531-5160," which combine caliber and case numbers. Thank you for viewing.
