Quick TakeThis is no ordinary time-teller, it's a companion built for the discerning globetrotter, a statement of rugged refinement. Its verdant dial calls to mind the tranquil hues of late summer forests, a nod to the majestic Mount Iwate visible from the Grand Seiko studio. Luminescent hands and markers emerge like fireflies as dusk settles, ensuring legibility whether you're chasing sunsets or navigating moonlit streets. The sapphire bezel, a window into horological mastery, frames this symphony of motion while adding a layer of hardy elegance. With each tick of its high-beat heart, it whispers tales of faraway places, a subtle reminder that time, like nature, is ever in flux. This is a timepiece not just for marking the hours, but for celebrating the journey, a wearable ode to wanderlust and the changing seasons, ready to accompany you through every adventure life throws your way, wherever it may take you!

DescriptionThe Grand Seiko Sport Collection timepiece, reference SBGJ239, has a stainless steel exterior. The case measures 44.2mm in diameter, 50.6mm in length, and 14.4mm in thickness, providing a robust structure that is water-resistant up to 20 bar, or approximately 200 meters. In addition, it has a magnetic resistance of 4,800 A/m and a weight of 122 grams, ensuring durability without unnecessary heaviness. A screw-down crown further enhances its water resistance. A dual-curved sapphire crystal with an anti-reflective coating on the inner surface protects the dial. This model features a rotating 24-hour bezel constructed from high-quality sapphire glass, which not only adds to the aesthetic appeal but also contributes to the watch's durability. The dial is a unique vintage green, complemented by a black and white bezel, offering a classic appearance. Lumibrite coating on the hands, indices, and bezel ensures visibility in low-light conditions. The timepiece is driven by the Caliber 9S86, an automatic movement with manual winding capability. It boasts a power reserve of approximately 55 hours and an accuracy of +5 to -3 seconds per day.

Functionality is at the core of the SBGJ239's design, featuring a mechanical Hi-Beat 36000 GMT movement capable of displaying three time zones simultaneously. The red GMT hand indicates the home time zone, while the 24-hour hand can be adjusted to display a second time zone, and the rotating bezel allows for a third. This caliber features a calendar-linked time difference adjustment function, enhancing its practicality for international travelers. The movement comprises 37 jewels, contributing to its precision and longevity. The watch is secured with a crocodile leather strap, 21mm in width, and fastened with a three-fold clasp that includes a push-button release mechanism. This combination of features and specifications makes the SBGJ239 a sophisticated yet functional timepiece, ideal for both everyday wear and global travel.
