Skyland V2 has a better case back. Better than V1 & V3 (same case). Logo on V2 is more embossed. Also the other engravings like type and serial# are better and more accurate on the V2. I did a review of both V1 and V2 (as I owned both) but I think the photos don't work anymore. I'll try if I can repost them later. Eventually I took the V2 case, V3 dial (whole lume dot at 3), V2 end-links (V1 & 3 don't have serial# on the end-links) and v1 bracelet because the finishing of the screws, clasp and fold was more superior. Voila, an almost perfect rep recipe
