Grand Seiko Brightens Dive Duo

Grand Seiko adds two new Spring Drive 200 meter diver’s watches to its already impressive Sport Collection. Both new models boast enhanced dial luminosity as Grand Seiko has coated the hands, markers, and bezels with newly generous amounts of LumiBrite.

In addition, the watchmaker has designed the bezels on both models to feature markers at every minute position, including the one at three o’clock to the right of the calendar frame, a slight change from existing diver models.

Both new models boast enhanced dial luminosity.

Both watches also measure 44.2mm in diameter, 14mm in thickness, and 50mm in length, and, as noted, boast water resistance to a depth of 200 meters. One model, Grand Seiko Spring Drive SBGA461, is cased in steel while the other, and Grand Seiko Spring Drive SBGA463, is cased in High-Intensity Titanium.

The latter watch provides heightened scratch and corrosion resistance, according to Grand Seiko, as well as a substantial weight reduction (about 30%) when compared to its stainless steel brother. Regardless of metal material, grand Seiko finishes each with contrasting hairline and Zaratsu-polished surfaces.

Both these dive watches are in full compliance with ISO dive watch standards, and even enhance these basic requirements with a magnetic resistance of 4,800 A/m.

Inside each model Grand Seiko fits its superb Spring Drive 9R65 caliber, which combines a mainspring with quartz precision.

Look for the Grand Seiko SBGA461 and SBGA463 to be delivered after December 15th. Prices: $6,100 (SBGA461) and $7,300 (SBGA463).
