GrandSeiko watches are often classic and formal, but sports series are usually larger in size and more casual in style. Recently, GrandSeiko added a new timepiece to the sports series-SpringDriveGMTSBGE248, which is also the brand’s first watch with a gold bezel and crown.
Previously, gold has been widely used in the manufacture of GrandSeiko cases, including the Heritage SBGW252 commemorative watch. GrandSeiko’s design is relatively conservative, and the two-tone appearance of gold and blue is the first time. The new SBGE248 watch is generously applied in gold, with eye-catching colors. The bezel and crown are made of 18K yellow gold, while the hour markers, hands and markers on the dial are gold-plated.
Although the bezel itself is made of gold, the insert is indeed sapphire crystal, which is the same as a standard SpringDrive GMT watch. The size is also generally the same, the case diameter is 44 mm. The case and bracelet are made of stainless steel.
This watch is equipped with a SpringDriveCaliber9R66 automatic winding movement, the average monthly error can be maintained within 15 seconds, and it can provide up to 72 hours of power reserve. Such incredible accuracy is due to a mechanical oscillator that is electronically adjusted, and this speed control mechanism is controlled by a quartz oscillator with an integrated circuit. In addition, the 9R66 movement also provides power for an independent second time zone hand, and can easily adjust the local time without stopping the movement.
