This is the link to my review of the GW-2500 series with resin strap and positive display. Most comments can be applied to the other watches in that series except notably those on the display and the strap. The metal bracelet will make the watch feel much heavier while not offering much more comfort because the resin strap is already very nice and soft, more like a caoutchouc strap. The negative display will make reading even with the built-in light almost impossible. With the positive display you get a chance at least.
Enjoy the review!
