The Grand Seiko Hi-Beat 36000 GMT is already known from collectors, and praised for its superior quality, its design mixing elegant and casual attitude and its highly technical movement. It is a watch that was already available in both standard editions and in one colorful edition (the SBGJ005, with its green dial and highly decorated rotor). Already at that time, we had two regular watches and one limited. Well, the same scenario is about to happen, with 3 new versions of the Grand Seiko Hi-Beat 36000 GMT: 2 elegant regular pieces (SBGJ017 and SBGJ019) and one limited edition with deep red dial and a rotor depicting the sunrise on Mount Iwate (SBGJ021).
