SEIKO Seiko 7548-700b Made in 1980. Operation confirmed. As expected of a SEIKO quartz watch, based on a visual inspection by an amateur, it keeps time almost perfectly. The band has been adjusted to approximately 17.5 cm (no extra links). Operation of the crown, time adjustment, and calendar adjustment are all problem-free. Operation has been confirmed, but as this is a model from over 40 years ago, support cannot be provided. No returns or claims accepted.
