Vintage Seiko 5 Sports 70M 'Rally Diver' (Ref. 6119-7173)

This is a vintage Seiko 5 Sports 'Rally Diver' automatic watch, likely dating from the early 1970s. The piece features a distinctive stainless steel cushion-shaped case with a multi-colored 'rally' aesthetic. The dial is a vibrant sunburst blue with luminous baton hour markers and a day-date window at 3 o'clock. Surrounding the dial is an internal teal/light blue rotating ring and an external black-and-silver bicolored bezel. The watch is equipped with a bold orange sweep second hand, a characteristic of this era's sports models. Notable manufacturing details include the 'Seiko 5 Sports' and '70 Proof' or 'Regist' markings often found on these models, indicating 70 meters of water resistance. The watch is currently paired with a non-original or aftermarket stainless steel link bracelet. Regarding condition, it shows heavy wear throughout: the crystal is significantly scratched, impacting legibility; the case and bracelet exhibit numerous scuffs and surface scratches consistent with age and frequent use. Most critically, the crown is missing from the 4 o'clock position, creating an open ingress point for moisture and dust. Despite the missing crown, it is noted to be in working condition, suggesting the internal 6119 caliber movement is still functional. The overall patina reflects a tool watch that has seen extensive real-world use.
