Partially verified

The Seiko Hi-Beat Professional Diver reference 6159-7001 is a self-winding wristwatch designed for diving, manufactured in 1969. Featuring a 44-millimeter stainless steel case, the watch incorporates an unsigned screw-down crown positioned at the 4 o'clock mark. The dial is finished in matte black and features applied indices with gold trim, gold-toned hands, and a sweeping seconds hand described as a "stoplight" design. The bezel is bidirectional and rotating, equipped with a luminous pearl at the 12 o'clock position. Luminous material on the hands and markers has developed a cream-colored patina with grey spotting. The watch is powered by a high-beat automatic movement and is currently presented on a two-piece rubber strap. The auction description reports the watch is functioning and keeping time, though the history of previous servicing remains unknown.

The bezel is bidirectional and rotating, featuring a black insert. It retains a luminous pearl at the 12 o'clock position. The auction house notes the bezel is in original condition and coordinates with the patina found on the dial.
