Seiko is going strong with the real GMT watches for non-GMT-prices :). This SSK025 has really nice green indexes (not lumed, the lume is in the minutes ring on the outside dial ring), and it has a GMT-hand that looks a lot like the Seiko signature seconds hand of the MarineMaster. The watch case is hardcoated black and the 24-hour markers are engraved in the fixed bezel, very subtle. The 24-hour markers are also in the dial, very small font. A bit too much maybe, my guess is that it is because of it is a field watch. The hands are brushed, very nice looking on the matt black dial. The glass is single domed hardlex, looks very good. (I am waiting to make sapphire, first I need to know if this case will be used more by Seiko).
There is a nice leather nato strap on the watch, it hinders the look at the movement, but it is a very nice strap and makes the look sporty. The power comes from the 4R34 movement, which is unlike the 4R37 a real GMT. To make the GMT function possible, the day mechanism has been altered. Nice side effect is the disappearance of the day-disc, and a much nicer dial with only a date window in it.
The lugs have been drilled, so changing the strap (already easy if you put in a new nato) is easy.

This watch is delivered in a special Seiko Sports watch box.
