About Grand Seiko SBGJ229
The Grand Seiko Sport Collection Blue Ceramic Hi-Beat GMT 36000
The Black Ceramic Models made its debut in 2016. It was the first Grand Seiko series to incorporate zirconia ceramic, a unique material that is seven times harder than stainless steel.
As part of 20th anniversary celebrations for Caliber 9S, zirconia ceramic returns in stunning Grand Seiko blue for the Hi-Beat GMT 36000 Limited Edition. Never before has the color of this resilient material been so vibrant. The remarkable scratch resistance and durability of zirconia ceramic means that this watch will retain its pristine beauty for many, many years to come.
Design in the Grand Seiko blue
The blue design motif resonates through every element of the watch. Complementing the subtly patterned dial in Grand Seiko blue are the blue indexes and tempered steel 24-hour hand. The bracelet and case are also executed with blue ceramic elements.
A special monogramed pattern
The dial carries the brand monogram, GS, and the caliber name, 9S, repeated in a pattern that radiates out from the center. The dial has a softly textured feel that adds warmth to the whole design.
The hour markers are in blue but their surfaces are coated in LumiBrite to create a nuanced accent to the dial. The hour and minute hands have Grand Seiko’s characteristic sharp edges and are also accented with LumiBrite to ensure visibility in any light conditions, day or night.
The GMT hand is in blue tempered steel, but, to ensure legibility of the time on the 24 hour scale, has a red arrow-head tip inset with LumiBrite.
Blue oscillating weight with an emblem
Even the oscillating weight, visible though the sapphire case back, is in blue, thanks to an anodic oxidation process applied to the titanium section. The Grand Seiko lion emblem is in 18k gold, set into the oscillating weight.
Titanium and ceramic in harmony
The case and the bracelet are constructed from high-intensity titanium and blue zirconia ceramic. The strength of the ceramic parts is balanced by lightness of the titanium to ensure that the watch is supremely comfortable to wear. Because of its light weight and its superior water resistance, the inner case is also made of titanium.
The Hi-beat GMT 9S86 caliber joins the ceramic series for the first time
Grand Seiko “Special” standard
To celebrate the 20th anniversary of Caliber 9S, the 9S86 hi-beat caliber is used and it is specially adjusted to meet the Grand Seiko “Special” standard accuracy of +4/-2 seconds a day.
The oscillating weight, durable against shock resistance
Behind the sapphire case back, titanium and tungsten combine in the oscillating weight to resist distortion even when the watch is subjected to shock. The titanium section of the weight is treated with an anodic oxidation* process that creates a new, rich and vivid blue that complements the Grand Seiko blue of the ceramic and the dial.
In recognition of the watch’s superior accuracy, the name “SPECIAL” appears at the 6 o’clock position on the dial.

Grand Seiko SBGJ229 History :
Prior to 1960, to challenge the status of Swiss watches and change the perception of Japanese watches, Daini Seikosha and Suwa began the discussion of a product line that can match the quality of Swiss watches under the suggestion of the parent company. At the time, Suwa Seikosha Co. was in charge of manufacturing men’s watches, so it was decided that Suwa would be producing the first Grand Seiko (GS).
The first Grand Seiko was released in 1960, it was based on Seiko’s previous high-end watch, CROWN. This Grand Seiko has a 25-jewel, manual-winding, 3180 caliber, and only 36,000 units were produced. This was also the first chronometer-grade watch manufactured in Japan, and it was based on Seiko’s own chronometer standard.
The design language of the Grand Seiko was set in 1967, with the creation of Grand Seiko 44GS. The 44GS set the ground for all future Grand Seiko with nine elements. These elements help improve the legibility of the watch under different situations, and create a sharp, crisp visual impression:
- Double width index at 12 o’clock
- Multi-faceted rectangular markers
- Highly polished bezel
- Highly polished planes and two-dimensional surface
- Half recessed crown
- Flat dial
- Multi-faceted hour and minute hands
- Curved side line
- Reverse slanted bezel wall and case side
- Dress style with simple but beautiful design
- Zaratsu polishing
