The latest Seiko Quartz I’ve added to my collect The latest Seiko Quartz I’ve added to my collection. A beautiful watch from the 38 family, dating back to the first half of the 1970s, featuring a stunning “Snowflake” dial. It houses a spectacular movement, often overlooked by those who don’t truly understand watches, simply because it falls into the quartz category. These models were positioned above most Grand Seikos of their time, and this was reflected in both their build and finishing quality, as well as their price. #seiko #watches #seikowatch #vintageseiko #seikoquartz #luxurywatch #grandseiko #watchfam
