Gnkt's post offers a captivating visual comparison of two highly sought-after Grand Seiko Hi-Beat GMT models, the SBGJ021 and the SBGJ005. His detailed photographs highlight the unique dial textures and color variations inspired by the changing seasons of Mount Iwate, providing invaluable insight for collectors interested in these limited-edition pieces. Gnkt's personal experience of witnessing the autumn colors in Morioka before encountering the SBGJ021 adds a unique narrative depth to his appreciation of its design.

















The Grand Seiko SBGJ001 is a distinctive Hi-Beat GMT model, part of the brand's mechanical collection, known for its high-frequency movement and GMT complication. This reference showcases Grand Seiko's commitment to precision and traditional Japanese aesthetic principles, offering a sophisticated travel watch within its core lineup. It stands as an example of Grand Seiko's ability to combine technical prowess with refined design.
Powered by the Hi-Beat 36000 GMT Caliber 9S86, the watch features a high oscillation rate of 36,000 vibrations per hour, contributing to its accuracy. The case is crafted from stainless steel, with a diameter of 39.5mm and a thickness of 13.9mm. It features a sapphire crystal with anti-reflective coating and is water-resistant to 100 meters. The dial is a deep, textured dark blue, complemented by a 24-hour scale on the rehaut for the GMT function.
The SBGJ001 is particularly relevant to collectors for its combination of the Hi-Beat 9S86 movement and its distinctive dial texture, which often draws inspiration from natural elements. Its stainless steel construction makes it a more accessible 'Special' edition compared to precious metal variants, while still offering the high level of finishing and mechanical performance expected from Grand Seiko. The watch represents a significant offering for those seeking a robust yet elegant GMT timepiece.
This watch is just beautiful. Regards John.
Fabulous comparison of the two great watches. So I see you\'ve got three seasons already - looking forward to seeing Seiko\'s Spring!
Great photos, and a lovely pair of GS limited edition hi-beat gmt! This is not to dismiss the quality of the 005 and 021 at all, but I think the 003 more than hold its own against the other 2. All 3 watches essentially have the same dial pattern and finish, except the difference in colour. Using seasonal themes as inspiration is no doubt a clever idea. I picked the black dial however because it serves as the best background to show off the razor sharp hands, which I consider to be a GS signature
003 is a nice GS but ... it's not in the same league as 005 and 021, IMHO This texture has been already used on a black dial, for SBGH005, while 005 and 021 are unique. The color variation is much more wider on both green and red dials. Concerning the background to show the razor sharp hands, have a look below ... Just my two cents ;-)
brink of puling the trigger on this one and your great pictures are so pushing me towards it! best
I do see your point on the black dial being used in the SBGH005 first. By the same logic, are the dials on 005 and 021 truly original? New colours-sure; but it's the same pattern. I had multiple opportunities to pick up a 005 and I passed, never considered the 021. Again, this is not to say they aren't very nice watches (they are), I'm only trying to make a case on why I'm very pleased with my 003. We can agree to disagree on which colour serves as a better background to the hands, I still prefe
