Serviced, stunning 1973 Seiko GS hi beat automatic in good condition on a new Seiko crocodile leather strap.
This is one of the less common 56GS models and not often encountered, making it one the most desirable GS with this caliber.
White textured dial nicknamed the “Nashi‑Ji” or “sand”, has a finely grained matte finish and pairs with slender black hands, creating a balanced, elegant contrast. There is a slight patina on the edge of the dial between 3 and 5 o'clock.
Case design is a class above the more common 56GS models with balanced aesthetic. The interplay of brushed and polished casework, plus the textured "sand" dial and slim hands, creates a refined yet sporty appearance. Edges are not as sharp as new and it had some polishing done, but overall condition is pretty good with some minor scratches.
Caseback is in great condition with gold medallion intact.
New mineral crystal.
New Seiko DA29, crocodile leather strap (¥14,300 )
Movement is also in excellent condition. Just serviced and running with very strong amitude and very good accuracy. Plastic star for calendar quick set, the weak point of this caliber, has been replaced with metal one.
