Grand Seiko GMT SBGM239

GRAND SEIKO X HODINKEE GMT SBGM239

A collaborative effort between esteemed Japanese watchmaker Grand Seiko and one of the largest watch publications in the world Hodinkee, the SBGM239 is perhaps one of the most wearable and easily-operable GMT timepieces on the market today. Made of stainless steel and featuring a wonderfully proportioned 39.5mm x 13.7mm case as designed by Grand Seiko Chief Designer Nobuhiro Kosugi, the SBGM239 is a timepiece that is hard to not enjoy. Offered as a limited edition release of 500 pieces exclusive to the US, the SBGM239 features a stunning dial that combines Grand Seiko’s nature-inspired design language with Hodinkee’s signature design details. Partially inspired by the hours that contain the transition from day to night; dusk in English, or "Yūgure" in Japanese, it features a twilight blue dial that boasts Hodinkee's signature shade of grey for its GMT functions, such as its 24-hour scale and GMT hand, which further feeds into this natural-inspiration given this same grey resembles the color of clouds. Powered by the automatic cal. 9S66 movement, the SBGM239 is tested to Grand Seiko's stringent -3 to +5 seconds per day Grand Seiko Standard in static conditions across six positions over a 17-day period to ensure it fits the brand's exacting standards. With a rather capable 72-hour power reserve, and a GMT function that is easy to operate, the SBGM239 is not only stunning, it is also incredibly practical; like so many other timepieces from Grand Seiko’s rich catalog of incredible timepieces.
