About this reference
The Grand Seiko SBGE257 brings a green sunburst dial to the Sport GMT format. Its 40.5 mm stainless-steel case is paired with a ceramic bezel and steel bracelet, while sapphire crystal, LumiBrite, and 200-metre water resistance give the compact traveller a confident practical edge. The solid case back keeps the silhouette purposeful, allowing the dial's changing green surface to carry the visual character.
Calibre 9R66 provides the underlying travel machinery: Spring Drive regulation, GMT, date, and a power-reserve indicator. The 30-jewel movement winds from a single barrel and runs for 72 hours, with accuracy stated at plus or minus one second per day. Its 32,768 Hz reference oscillator and smooth central seconds make the technical story visible in use, even though the movement itself remains behind the case back.
