Model: Grand Seiko 6156-8010 Special, with Faceted Crystal

Year: June 1971

Features:

Faceted Crystal. Two angled facets surround a central plateau, giving this sapphire crystal remarkable side profile, with a subtle look when viewed from the front. An ambitiously shaped crystal, especially when you consider it was one of Seiko's earliest examples of a sapphire crystal. This style of faceted crystal can only be found 8010 variant of the 6156 series.

Not COSC Certified. After a fallout with the Swiss in 1968, Seiko decided to shun the COSC certification process, instead creating their own "Chronometer" style of test, and the first two graduates were the VFA and the 6156 Special. The 6156 Special was certified to an accuracy of -/+3 seconds per day - a remarkable feat, even by today's standards.

The Excellence. The 6156-8010 on offer today embodies this spirit of excellence. This rare Hardened Stainless Steel (HSS) variant features two vertical facets on its sapphire crystal, a bi-lingual quick-set day/date complication, and the iconic, solid gold, medallion.

The Case. The case demonstrates Taro Tanaka’s “Grammar of Design” philosophy, while its 36mm size is as classic as Grand Seiko gets. The dial, like others from this era, has developed a speckled patina, adding character to its authentic vintage appeal.

The Movement. 36,000 bph. Silky smooth. A true hi-beat even by today’s modern standards, so it goes without saying how remarkable this was in 1971. Serviced in 2024 by a specialist Vintage Grand Seiko company in Tokyo, Japan and currently running at an average of +2 second per day across six positions. 

The Medallion. The GS medallion on the caseback is in great condition, and it serves as another hallmark of vintage Grand Seiko craftsmanship.

Condition: It’s in great condition overall. The sapphire crystal is immaculate, and the HSS case only has mild signs of wear. The edges and original brush marks are sharp. The medallion on the caseback is free from any signs of aging or damage. The strap is aftermarket.

Scope: No box, manual or papers.

          FAQs

          Are your watches authentic?

          Everything we sell is 100% authentic.

          All of our watches are inspected and verified for authenticity - both inside and out. We have over 15 years of sourcing and collecting rare watches in Japan, which is often considered to be one of the best markets for authentic and fully original vintage watches.

          Do you ship globally?

          We are based in Japan and regularly ship all over the world. We typically use FedEx and it takes:

          • 3-7 business days to reach North America
          • 3-7 business days to reach Europe
          • 3-7 business days to reach Asia and Oceania.

          All of our packages are securely shipped, fully insured, and trackable door-to-door.

          Are all of your watches serviced?

          Most but not all of our watches are serviced. The "Condition" section of each watch will confirm if the watch has been serviced.

          All of our watches are tested by an independent watchmaker - if a service is needed, the watch will be serviced. If a service hasn't been conducted, it's because the watch itself is too new to need a service, or there is evidence of a recent service.

          What payment methods do you accept?

          We accept payment by all major Credit Cards and Wise.com

          What condition are your watches?

          Due to the vintage and neo-vintage nature of the watches we typically sell, the condition varies from watch to watch. However, our photos are high resolution and our descriptions are accurate. You can buy with confidence knowing there won't be any nasty surprises.

          If the condition of a watch is ever misrepresented, we would offer a full refund.

          Do I have to pay customs or taxes?

          It depends on so many factors, including but not limited to the cost of the watch, the type of watch you've bought (vintage or new), and the import laws of your country. If you're unsure we recommend checking the import laws that relate to your country before ordering.

          Are your watches water resistant?

          Our serviced watches are typically tested to their original water resistant specifications, but we would never recommend pushing vintage or neo-vintage watches to their depth limits.

          What is your returns policy?

          Due to the vintage and neo-vintage nature of most of our watches, we do not offer returns under normal circumstances. All sales should be considered final.
