Seiko 38SQW 010 and 014 with their original bracel Seiko 38SQW 010 and 014 with their original bracelets! As is often the case with quartz models from the 38 series, they were sold as “non-working” watches, but all it took was a simple battery replacement to get them running flawlessly. To this day, I don’t think I’ve ever come across a single non-functional watch from the 38 series, a true testament to the incredible quality of these quartz movements, still accurate after more than 50 years. #seiko #watches #vintageseiko #seiko38sq #seikoquartz #vintagequartzwatches #seikowatch
