The Grand Seiko Spring Drive Diver SBGA071 is stainless steel case and bracelet, using Seiko’s impeccable Zaratsu (Katana Blade) polishing technique. The mirror quality finish can be found on the case sides as well as middle links of the bracelet. The case is 44.2mm wide, 14mm thick and has a solid case back engraved with with the watches 1-200 serial number. The crown is fairly large, and makes for very easy smooth setting, but is also guarded by a crown protector in case of any potential damage that can occur in diving. Should the crown be opened, there will be a red stripe exposed to help prevent you from jumping in the water before screwing down the crown.
The movement utilized is Seiko’s in-house manufactured and developed 9R65 Spring Drive caliber. There is much to be said about Spring Drive, all being great. For such a utility watch, only the finest movement is worthy of being inside of the timepiece. Spring Drive’s immaculate accuracy, durability, and 74 hour power reserve are the perfect fit for this diver. The gliding motion is mesmerizing, not to mention incredibly accurate. Rated at +/- 1 sec a day, the performance is most likely to fall within a 1-3 sec a month deviation, judging by customer feedback and personal experience.
The lume on this piece is very powerful. Helpful in the darkest of settings and made to last long throughout the night (or in really dark waters). The proprietary Lumi Brite luminescence is the same utilized in the highly acclaimed Seiko Space Walk. This is some of the brightest natural lume you can find in the watch world.
