Vintage Seiko 5 Sports 70M Diver 'Regatta' Watch (Reference 6119-6053)

This is a vintage Seiko 5 Sports automatic wrist watch, commonly known amongst collectors as the 'Regatta' or 'Double-Inner Bezel' model, likely dating to the early 1970s. The piece features a distinctive stainless steel cushion-style case with an approximate diameter of 41mm. The dial is a deep midnight blue with applied baton markers and a day-date window at the 3 o'clock position (displaying 'THU 11' in black on white). It possesses two internal rotating rings: a light blue ring for timing and a teal/green ring, complemented by an external black and red 'Pepsi' style count-up bezel. The hands are white batons with a bright orange contrasting seconds hand. The watch is mounted on an integrated-style stainless steel link bracelet with visible scratch wear and heavy scuffing, indicating significant use. The mineral crystal shows several prominent scratches, particularly a heavy one near the center and top-left. The case displays sharp edges but exhibits various micro-scratches and surface dirt. The craftsmanship is typical of Seiko's high-quality tool watches from the era, utilizing the robust caliber 6119 movement. Condition is fair to good, appearing to be in original, unpolished state with heavy patina and evidence of daily wear, which is often preferred by vintage enthusiasts for its 'honest' character.
