Grand Seiko has always been a pioneer in watchmaking. Grand Seiko has everything from regular beats to spring drives from mechanical movements to high-end quartz movements. However, by launching Grand Seiko Sport GMT Hi-Beat SBGJ239 and SBGJ237, Grand Seiko once again proved itself as a giant in the industry.
At a glance, these two new versions may look and feel familiar. Presumably, this is because they are based on the same ideas as the current GMT watches of the Sport series such as SBGE251, SBGE215 and SBGE201.
In addition to the new color schemes and combinations, the current SBGJ239 and SBGJ237 have also undergone major changes. One of the most important differences is that Grand Seiko uses a mechanical engine instead of the traditional Spring Drive movement. Let us learn more about these watches.

What do these watches offer?
The design, case and bezel of these two watches are the same. These have the same case design, strap and bezel location, but slightly different color schemes. SBGJ237 has lovely blue and white, while SBGJ239 has white and green patterns. Let us find out what products Seiko offers.
case
The latest Grand Seiko Hi-Beat GMT SBGJ239 and SBGJ237 provide a relatively wide case design. Since these watches belong to the sports series, the diameter of the case is 44.2 mm and the height is 14.4 mm.
Both designs are very suitable for people with wrists longer than 17 cm, and can be comfortably wrapped around the wrist. In addition, the cases of these two watches are designed, manufactured and assembled according to GS.
The combination of fine texture and polished highlights, the Zaratsu method provides a smooth and clean surface. The back covers of these two watches have been closed, and together with the screw-in crown, the watch provides a convenient 200 m waterproof function.
Internal movement
Grand Seiko cancelled the Spring Drive movement and chose the 9S86 movement to power these GMT models.
This movement beats at a rate of 36,000 vibrations per hour. Grand Seiko can precisely adjust this movement with an accuracy of +5 to -3 seconds per day.
This movement further provides a power reserve of 50 hours. Grand Seiko also includes a date window at 4 o’clock. In this GMT setting, this function is meaningful.
Color scheme and bezel
For these new mechanical Hi-Beat movements, Grand Seiko chose the stylish green dial type on the leather strap, high-end surface treatment for the SBGJ239 model, and the lovely blue dial on the metal bracelet for the SBGJ237 model . It looks great and is an excellent choice.replica watches online
The first thing that attracts attention is the gorgeous bezel around the dial. This is a two-way baffle and is equipped with a 24-hour scale. When in front of the central hour hand, this is the second time zone.
The material, color scheme and two-tone realization of the bezel bring great flavor to the watch. This two-tone scheme reflects the time of day and night, and Grand Seiko printed the scale on the inside of the insert. Grand Seiko marks the bezel with black during the day and green or blue at night.
