Grand Seiko SBGF021 is a real gem for lovers of older Grand Seiko. A rare model with a characteristic black dial with a texture called “Tatami” by collectors.
However, the most interesting caliber is 8J56. It is a thermocompensated High Accuracy Quartz mechanism with an accuracy of approximately ±10 seconds per year. Additionally, it allows you to independently adjust the hour hand without stopping the watch.
Many Grand Seiko 8J56 fans value it even higher than the later 9F. Not because of officially better accuracy, but because of the solid construction and the “jumping hour hand” function.
In addition, there are great performance parameters: a 38 mm steel case, only about 10 mm thick, sapphire glass, LumiBrite and water resistance to 200 meters.
For me, these old, unusual Grand Seikos have great charm. They are discreet, technically very interesting and increasingly difficult to find in really good condition.
Visual condition: excellent.
Full length bracelet.
The set includes a box, books and documentation from the watch service in Japan.
