Have had my green day/date Airfield for a couple of weeks now and I'm very impressed with it.
The 40mm case, whilst a little thicker than I would normally go sits comfortably on my 7" wrist without feeling top heavy and is exceedingly well finished. The seiko NH movement is working flawlessly and within +/- 1 per day. The bracelet is really comfortable and, with both screw pins to the links plus clasp micro adjustment holes is very easy to adjust and get just right.
I went for the green dial variant to get away from the monotony of the standard blue/black/white dial watches that seem to dominate my collection. Dial looks great albeit only negative is that the day/date window in green with white printing can be a tad hard to read in lower light conditions with my eyesight. That said, it looks so much better with the date window colour co-ordinated to the dial so I can live with that - just will need to turn on a light!
All in all, a very accomplished watch and excellent value of the money
