Grand Seiko adds two new GMT models to its Sport Collection, and both are powered by the hyper-precise Grand Seiko quartz Caliber 9F86.
The duo, Grand Seiko models SBGN027 and SBGN029, both feature a design built with a 39mm steel case, slightly smaller than most models in the collection.
One model, SBGN029, features a blue sunray dial with red accents—-most notably a red GMT hand to indicate a second time zone. The other debut, SBGN027, features a black sunray dial with monochromatic highlights.
Using the clearly differentiated GMT hand, the wearer of either model can quickly note the second time of choice using the 24-hour dial ring, which is divided into two 12-hour sections for AM and PM.
Both watches offer hands and dial indexes with generous Lumibrite coating for superior visibility in darker conditions. In addition, each watch is rated to 100 meters of water resistance and features a screw-down crown and a dual-curve sapphire crystal.
Grand Seiko supplies both models with its well-known three-row steel bracelet with high-end Zaratsu-polished surfaces .
Grand Seiko collectors are familiar with Caliber 9F series, which the watchmaker created as the “ultimate quartz watch.” This Caliber 9F86 provides extremely high accuracy, with a rating of +/-10 seconds a year. And critically for a travel watch, the movement allows the wearer to adjust the hour hand without interrupting the timekeeping. 
Price: $3,300 (available in September).
