[AVAILABLE ✅] - Hex-Crown Precision: 1969 Seiko Presmatic Hi-Beat 27 Jewels (Ref. 5146-7030)
This serviced Rare Vintage 1969 Seiko Presmatic Hi-Beat Ref. 5146-7030 is an incredible mechanical milestone from the Kameido (Daini Seikosha) factory, showcasing the pinnacle of their late-1960s technical ambition. It is powered by the rare, high-tier 27-jewel Caliber 5146 movement, a high-frequency engine beating at 28,800 vibrations per hour. This caliber was engineered to rival the best chronometers of the era, introducing a fascinatingly unique quickset date system operated via a hex-button integrated directly into the center of the crown.
Following a full mechanical service, the hi-beat caliber delivers the exceptionally smooth sweeping motion and crisp operational accuracy that defined Seiko's golden era. The classic silver sunburst dial is in 100% original condition, featuring bold applied indices with black contrast inserts and matching sharp hands. The framed day-date complication at 3 o'clock remains perfectly crisp, presenting a highly legible, executive layout that catches the light beautifully across its radial finish.
The stainless steel case is remarkably well-preserved, retaining its original factory geometry and the distinct, robust cushion-style shape that defines the 7030-series profile. A major highlight of this specific specimen is its complete state of preservation; it remains entirely original, seamlessly paired with its factory-correct original Seiko Presmatic stainless steel bracelet. Keeping its original dial, crystal, case, and specialized crown fully intact, this watch offers the absolute maximum historical value for discerning collectors.
The Presmatic 5146 is fiercely hunted by vintage enthusiasts for its mechanical uniqueness, its high jewel count, and its short production lifespan. This 1969 specimen delivers an exceptional combination of rare engineering and commanding retro styling - a distinctive, all-original cornerstone piece for any serious vintage Japanese collection.
