Quick TakeThe Grand Seiko SBGM247 is a rugged GMT timepiece that's ready for adventure! Picture yourself globe-trotting with this companion, its vibrant green dial and bold orange GMT hand keeping you on track across time zones. Don't be fooled by its polished exterior; this is a workhorse, built with a durable stainless steel case and a 72-hour power reserve from its automatic movement. It's like having a mini, mechanical powerhouse on your wrist. The SBGM247 is more than just a watch–it's a statement piece that screams "I'm ready for anything!" This is a rugged, go-anywhere companion, built to withstand the rigors of an adventurous lifestyle. The GMT hand provides an additional point of reference, making it easy to track multiple time zones simultaneously, whether on business or a pleasure trip. The GMT function is not just a practical addition; it's a reminder that the world is a vast and exciting place, waiting to be explored.

DescriptionThe Grand Seiko SBGM247, part of the Sport Collection, is constructed with a stainless steel case and bracelet. This timepiece has a diameter of 40.5mm, a lug-to-lug measurement of 48.6mm, and a thickness of 14.4mm, making it substantial yet not unwieldy. The case back is a screw-down type, contributing to the watch's impressive 20 bar (approximately 200 meters) water resistance, which allows it to be used for recreational diving. A dual-curved sapphire crystal with an anti-reflective coating on the inner surface protects the dial. This timepiece features a 9S66 automatic movement with a manual winding capability, which provides an impressive 72-hour power reserve and an accuracy rating of +5 to -3 seconds per day. The mean daily rate is determined by evaluating the movement in six positions under controlled conditions for 12 days before it's cased. This movement is equipped with a 24-hour hand for dual time display, a calendar-linked time difference adjustment, and contains 35 jewels.

The SBGM247’s stainless steel bracelet, with a width of 20mm at the lugs, has a three-fold clasp with a push-button release mechanism. The maximum perimeter of the bracelet is 192mm. The dial features LumiBrite on the hands and indexes, ensuring visibility in low light conditions. Further enhancing its functionality, the watch boasts a magnetic resistance of 4,800 A/m. The screw-down crown, thoughtfully recessed at the 4 o’clock position, adds an extra layer of security against accidental adjustments. This GMT hand's distinctive shape and vibrant orange color create a striking contrast against the green dial, ensuring it's immediately readable. The movement is designed to allow adjustment of the hour hand without stopping the seconds hand, preserving the watch’s timekeeping accuracy even when changing time zones. The watch weighs in at 180 grams, which is appropriate for a robust sports model like this one. With its blend of practical features, precision engineering, and durable construction, the SBGM247 stands as a reliable choice for the traveler and sports enthusiast.
