KIH presents a rare and insightful look into two exceptional vintage Grand Seiko timepieces: a 56GS with a distinctive TV-shaped case and an original first-generation Grand Seiko in stainless steel. This post not only showcases the aesthetic and historical significance of these watches but also highlights their impressive accuracy after being serviced by a renowned Seiko watchmaker. KIH's personal acquisition and a friend's piece offer a unique collector's perspective on these horological treasures.



The Grand Seiko SBGW033 is a limited edition model released to commemorate the 130th anniversary of Seiko's founding. It is a re-creation of the original Grand Seiko from 1960, capturing the aesthetic and proportions of that seminal timepiece. This reference is distinguished by its faithful adherence to the design principles of the first Grand Seiko, offering a direct link to the brand's heritage of precision and craftsmanship. It represents a significant piece for collectors interested in the foundational designs of Grand Seiko.
The watch features a stainless steel case, carefully polished to a high standard, measuring 37.6mm in diameter. It houses the manual-winding Caliber 9S64, known for its stable performance and a power reserve of approximately 72 hours. The dial is protected by a box-shaped sapphire crystal, which enhances the vintage appeal while providing modern scratch resistance. The solid case back further emphasizes its classic design.
This reference appeals to collectors who appreciate historical re-creations and the understated elegance of early Grand Seiko designs. Its limited production run makes it a sought-after piece within the collector community. The SBGW033 stands as a testament to Grand Seiko's enduring design language and its commitment to mechanical watchmaking, offering a blend of historical significance and contemporary quality.
. . . uncommon vintage GS, both touched by the hand of The Master . . . . . . and bound by friendship. What more can anyone say? :-)
.. may the watch be with you for a long, long time....
Both are very nice designs, but the FIRST ss GS is amazing! I really love that domed crystal shape on top of the very simple sunburst dial.
Same sort of shape and era but very different price point and technology! Cazalea

Grand Seiko Ref: 5645-5010 is simple gorgeous and rare. The dial is unique, as is the case shape and superb timekeeping. How many did they make of this model? Of course, I may have to commission you to look for weird Grand Seiko like this for me in Japan....? I miss my foraging trips to Ueno. Regards, MTF
