This serviced 1967 Seiko Seikomatic-P Ref. 5106-8010 represents a major technical highlight of Seiko’s late-1960s mechanical watchmaking. Powered by the high-grade Caliber 5106, this 33-jewel automatic movement features Seiko's ingenious "Presmatic" quickset date system, operated by pressing the unique central pusher integrated directly inside the crown. Following a complete service, the movement operates smoothly with crisp date changes and accurate timekeeping suitable for daily wear.
The original silver sunburst dial remains in pristine vintage condition, adorned with multi-faceted applied hour markers, sharp baton hands, and a framed day-date calendar window at 3 o'clock.
The 36.5mm stainless steel case retains its bold original geometry, featuring sharp facets and unpolished vintage character. This piece stands out for its absolute completeness: the original dial, signed "Presmatic" crown, crystal, case, and rare factory original stainless steel bracelet are all 100% original and factory-correct.
A highly collectible, all-original 1967 reference featuring an operational Presmatic quickset mechanism, high jewel count, and full original bracelet architecture—a true standout for vintage Seiko enthusiasts.
