Condition – Very good vintage condition overall for this reference. The dial shows beautiful even aging, with creamy lume plots that have developed warm patina consistent with early 1960s Seiko divers. Hands retain their original tritium with matching tone. The bezel insert shows light wear with subtle fading that adds character but no major chips or cracks. The stainless-steel case remains sharp with honest wear and hairlines from age. Crystal shows light marks typical for its age but remains clear and legible. The aftermarket mesh strap is clean and comfortable, with minimal wear, and fits a ~7.4 inch wrist. The movement winds smoothly and runs well for its age. Box & Papers – Watch only. No original box or papers. Price – $2299 shipped via Zelle or bank wire.

Overview – Vintage Seiko 6217-8001 “62MAS”, the first professional diver from Seiko and the foundation of all modern Prospex models. This early example features the original 150 m “Water Proof” dial, automatic Caliber 6217A, and clean case geometry. Its naturally aged dial and bezel create a striking vintage aesthetic that collectors seek. A true piece of Seiko dive-watch history and an excellent candidate for any vintage-tool-watch collection.
