It is no secret we love Grand Seiko here. Almost all of our editors have one, be it new or vintage. But are we open-minded enough to buy a Grand Seiko with quartz movement?In a recent article, we answered one of our reader's questions about spending a significant amount of money on an expensive watch with a quartz movement. The watch we have here today, is a Grand Seiko GMT SBGN005G with a caliber 9F quartz movement. A watch for the traveller that needs a precision piece with the ability of reading the time at a glance in other time zones. There are cheaper watches that offer this functionality of course, but those who appreciate craftsmanship, superb finish and a companion for life might be better off with the watch we have here.Grand Seiko GMT SBGN005GThis watch is part of the Grand Seiko Sport Collection, the other two collections are the Elegance and Heritage collection. From there on, all the models have a specific reference number and not a model name. Luckily, Grand Seiko aficionados are creative minds and have given some of the Grand Seiko references nicknames. What to think of the Snowflake or Mt. Iwate, and when it comes to Seiko, there are numerous nicknames. That said, today we are talking about the Grand Seiko GMT SBGN005G. Other watches in the Grand Seiko Sport Collection are the Spring Drive diver models (like the SBGA231 that we reviewed here) and the Spring Drive chronograph models. Compared to those, this GMT looks much more discreet, with just' an extra hour hand and a 24-hour bezel. The watch has a bit of that Explorer II flavour because of the steel bezel with black-filled engraved numerals and the Oyster-style bracelet but definitely isn't a copy.Details, Details, DetailsThe first thing to notice about this Grand Seiko GMT SBGN005N is the blue dial with sunburst finish. Upon closer inspection, you will discover the two-tone ring (rehaut) to indicate day night, where the lower part is grey, and the upper part is dark blue. The extra hour hand, or GMT hand, is bright red and matches the GMT' printing on the dial. As you can only expect from Grand Seiko, the applied hour markers and razor-sharp hands are facetted. The hour markers are high-polished, and you'll see that some of them have a different shape. At the end of the hour marker, lume has been applied for better readability in the dark. As always, the hands are a combination of a brushed and polished finish and also filled with lume. The GS logo, as well as the Grand Seiko wording, have been applied at 12 o'clock. Although you could say it is a very clean design, and far from cluttered, a lot is actually happening. You just need to be a bit of a watch nerd to see all these things. Or appreciate them.Case FinishingThe details aren't limited to the dial, also the case and bracelet show an incredible effort made by Grand Seiko. The finishing of the case is beautiful. The Zaratsu (mirror blade) polishing and satin finished surfaces combine perfectly on the 39mm x 12.1mm case. The design is not as extreme as their models with the 44GS case style (such as the SBGJ201 Mt. Iwate), but very wearable and the level of finish is impressive. The stainless-steel bezel with 24-hour engraving has a satin finish on top and polished surface on the side. The long Zaratsu polished lugs have a nice curve and on the inside of them, you have a small satin finished surface. The case band has a satin brushed finish as well, with the exception of the crown guards, which are polished. The GS signed crown is easy to grasp and is screw-down, to ensure some water resistance. On the case back, you will find the GS medallion of the lion in the center and on the lower half, a few specifications have been engraved. As you know, inside there's a quartz movement and (unfortunately) there's no sapphire crystal to show its beauty. Although some people will disagree, as you willC thenC also see the battery.
