Case and Crystal The stainless steel case features a distinctive square "TV" shape with substantial lugs that give it a strong presence on the wrist. The case finishes alternate between brushed surfaces on the top and polished sides, all of which remain sharp and well-defined with only minor handling marks, maintaining a clear and unobstructed view of the dial.

This movement is equipped with the "Second Setting" hacking function, allowing for precise time synchronization. The movement is currently performing well, showing a rate of +27s to +31s per day on the timegrapher, which is an acceptable rate for a vintage mechanical timepiece of this age.

Remarks The Seiko 5 Actus series was marketed towards the young, style-conscious Japanese professional in the 1970s, and this specific reference is a perfect time capsule of that era. The combination of the green gradient dial and the high-jewel count hacking movement makes this a highly collectible and wearable piece of horological history. History Produced in December 1974, this watch hails from the golden age of Seiko's mechanical mass production. The 6106 movement inside is considered one of Seiko's workhorses, known for its durability and engineering quality. The Actus line served as a bridge between the standard Seiko 5 and the higher-end Lord Matic series, often featuring more daring designs and higher-grade finishing that have made them favorites among modern vintage enthusiasts. / Second Vintage SKU: SEI-SSS-0006
