The 15400 is a nice watch. I looked at it and considered one, but went with the iconic 15202. Actually, another SFer recently PM'd me regarding the 15400 vs. the 15202. He actually had purchased a 15400 a little while ago, but had not worn it yet. He had this nagging feeling that maybe he should have gone with the 15202. After some chatting about the various merits of each, and a bit of my bad influence, he traded the 15400 toward a 15202. Each is a really great watch. The 15400 is a bigger thicker case and bracelet, which might be useful if you are really tough on a watch. The 15202 is as close as you can get to the original RO released 40+ years ago, and there are certain nuances that I find more appealing in terms of design, and its historic importance.
