Grand Seiko may not have invented the GMT watch – that accolade usually goes to Rolex or Glycine, depending on your definition – but the brand may have perfected it. The luxury subsidiary of Seiko currently lists 46 GMT models in its three main movement groups: Spring Drive, Hi-Beat Automatic and High-Accuracy Quartz, and it has just added two more.
The latest Grand Seiko GMT watches are part of the brand’s Sport collection and are powered by the Caliber 9F86 quartz movement. Like all Grand Seiko GMT watches, the new watches are “true” GMTs, so called because they feature an independently adjustable hour hand that can be changed to align with new time zones when traveling without interrupt other timing functions. 9F quartz movements also have other high-end features that set them apart from typical quartz, such as instant date change, a double-pulse check motor for more precise hand movement, and 10-second-per-year accuracy. .
The new watches – SBGN027 and SBGN029 – are essentially updated versions of the fan-favorite SBGN003 and SBGN005. Like those watches, the new GMTs feature a fixed stainless steel bezel with 24-hour marking, a 39mm case, three-link stainless steel bracelet, sapphire crystal, Discreet two-tone inner bezel, 100m water resistance and Lumibrite. However, they are not the same as their predecessors, as the new watches feature an updated design language consistent with other recent GS releases. This includes moving the crown and date window to four o’clock, a sleeker case, and larger, less pointed hands.
The SBGN029 combines a sunburst blue dial with a red GMT hand, while the SBGN027 opts for a monochrome look with a black dial with a white fourth hand. Both watches are available for pre-order now from Grand Seiko’s online store, with a price tag set at $3,300 and deliveries expected to begin September 1.
