Description

Ages 14+

This is an exceptionally rare July 1971 Grand Seiko "56GS" Vintage Automatic (Ref. 5641-7000), completely original and beautifully dynamic. Highly revered by elite horology purists, this specific variant stands as the ultimate "connoisseur's choice"—an incredibly rare Non-Date execution that showcases a flawlessly symmetric dial, backed by a pristine, unpolished factory solid gold GS caseback medallion.

Product Highlights:

  • Ultra-Rare Non-Date 56GS Profile: While the majority of Cal. 5646 movements housed day-date windows, the elusive Cal. 5641A strips away complications to emphasize the pure, unblemished geometry of the dial, making it significantly scarcer on the vintage market.

  • Pristine Solid Gold GS Medallion: A true miracle find for collectors—the caseback preserves its original solid gold "GS" factory center emblem in near-flawless relief contour with zero degradation or erosion.

  • Legendary Hi-Beat Heart: Driven by the in-house Suwa Seikosha Cal. 5641A automatic movement ticking at a precise high-frequency 28,800 BPH (Hi-Beat), engineered during Seiko’s historic era of absolute chronometer dominance.

  • Luxury Brand-New SEIKO Genuine Leather Strap: Freshly paired with an authentic, premium black textured SEIKO factory original leather strap (Strap Model: DAE4R 18) with fresh steel hardware.

Condition Details (100% Honest Antique Disclosure):

  • Status: Excellent Vintage Condition / Fully Operational & Winding Smoothly.

  • Movement: Spins up effortlessly via the original signed "GS" crown. Holds standard vintage power reserve and maintains reliable daily time tracking.

  • Cosmetics: The stainless steel cushion mid-case retains its sharp faceting but displays expected, honest antique micro-scuffs, bezel edge rubs, and hairline handling scratches from historic office wear. The original white dial is remarkably crisp with no heavy moisture spotting or edge peeling.
