This timepiece represents a crucial, slightly more dressy step in Seiko's dive watch history, positioned just below the professional 6309 and 6105 models. The Seiko SilverWave, reference 6306-8010, is an official Japanese Domestic Market (JDM) model and is part of the first generation of models to feature the iconic wave logo on the case back. It is powered by the dependable Seiko Caliber 6306 automatic movement, which is highly regarded for its robust architecture and features a valuable hacking function (the seconds hand stops when setting the time), a feature often missing on its automatic counterparts.
The dial is the standout feature, showcasing a fantastic, intricate "Snowflake" textured pattern in silver, which gives it a high-end, almost Grand Seiko aesthetic. The applied baton markers and the integrated stainless steel case and bracelet complete the classic 1970s sports-dress look. The serial number 652652 confirms a production date of May 1976 (based on the first digit '6' and the second digit '5' for the month), placing it in the prime of this model's production. This piece is a must-have for a collector who appreciates high-quality automatic movements and unique, detailed dial designs.
