Grand Seiko SBGJ239 Review

The Grand Seiko SBGJ239 is rich in features with a sober look. It offers exceptional performance with a pivoting 24-hour bezel that shows three distinctive time regions. The look and design have a significant presence while maintaining the conventional sparkle of this exemplary Grand Seiko model.

It is an exceptional sports watch, water resistant down to almost 20 bars, and has been idealized as an extravagant watch for dynamic players on the worldwide stage. The elegant, strong sapphire glass on the outside of the ring gives a solid feeling of straightforwardness, expansiveness, and profundity. The vintage green dial and dark white bezel made of sapphire gems give the feel that is innate to all high quality watches.

This new, exceptional Grand Seiko SBGJ239 has been added into the Sport collection and will be available at the beginning of July. It comes with all the features that buyers would hope to find in Grand Seiko GMT; however, it comes with additional items for the people who need a more dynamic touch. It is water resistant with up to 20 bars (or around 200 meters) and has a sapphire gem bezel, which ensures a radiant 24-hour scale. At night hours or in dark times, the numerals light up with Seiko’s Lumibrite.

It is pertinent to mention that Grand Seiko has utilized Lumibrite on a GMT bezel previously. The SBGE248, delivered a year ago, utilized a Hi-beat development with brisk setting for the region hour and a pivoting 24-hour bezel, which can rapidly tell the time in three time regions. The watch offers the region time, the time told with the 24-hour hand by means of the fixed 24-hour track on the flange, as well as the time that can be determined by turning the blue and white (or highly contrasting) exterior bezel in one hour additions and perusing from the 24-hour hand.

This new Grand Seiko SBGJ239 is astonishing and exceptionally alluring. It is worn on a leather strap, something distinct in the Sport collection. The dial has a dull green tone over a sunray-brushed surface and the shading is circumspect. A similar design is utilized on the bezel, which depends on dim green and white areas. The dial is empowered by red accents on the GMT hand and the GMT printing at 6 o'clock. The major aspect of the design, however, is the size; the case is 44.2mm wide and 14.4mm thick. The other notable design aspect is the somewhat topsy-turvy look of the bezel. The bezel is iridescent, which undoubtedly bisects the 6 and 18 hour numerals, similar to the Rolex GMT-Master. This impact is reflected on the second 24-hour scale on the spine. The fixed 24-hour scale on the rib is a phenomenal touch that makes the second and third time regions much easier to see.

This watch is for the people who venture to the far corners of the planet and love to wear high quality watches. The SBGJ239 is an amazing travel partner, but it is also a perfect everyday watch. Despite its size, it wears comfortably with its calfskin tie and with collapsing clasp. This green dial GMT is also a nice touch.
