Five years ago in 2009, Seiko had introduced its first Hi-Beat caliber in nearly 41 years. For this five year anniversary, Seiko introduced a whole new caliber to this line up. The 2009 9S85 caliber with 36,000 bph escapement was evolved upon adding a new complication, a GMT, and labeling it the 9S86. With 2 production models and 1 limited edition already released, we would like to introduce you to 3 different and very “SPECIAL” models of this new Hi-Beat GMT. Today we bring you the Grand Seiko Hi-Beat Special GMT’s in 18k white, yellow and pink gold, SBGJ007, SBGJ008, and SBGJ010.
For the first time in Grand Seiko’s history, the introduction of the 9F high accuracy quartz movement has been placed into a new 200m divers design. Spring Drive has been the only movement utilized in Grand Seiko’s diver models, which is due to their high accuracy and durability. With these two essentials in mind, it only makes sense that Seiko would give the extremely accurate and very durable 9F Quartz, a home in a dive piece.
There are two new models featuring the quartz movement. SBGX115 with a new white dial is the first, and the SBGX117 with traditional black matte dial is second. Both these models are in a 42.7mm stainless steel case that is 13mm thick and features Zaratsu polishing around the cases lugs. The models are mostly a brushed finish, including their stainless steel, 3 pieces oyster style bracelets.
