That's not detail. It's a sharp rendition of the side of some watch or other. It's certainly unlike the watch I'm wearing now. Maybe it's a Rolex. Who knows? On consensus: well, it's a matter of consensus on interpretation of the policies. Here's a relevant policy. Look, here, by contrast to this hodgepodge on Rolex, is an article that has been occupying me this week. As it happens, the article has only been edited by me so far, so in its current, prevandalized state you see my understanding of Wikipedia. (Of course I hope that others will join in and improve it.) Everything in it is sourced. It also dispenses with trivia: the man's choice of camera is far more important to his achievements than Che's choice of wristwatch was for his; but since I'm quite sure he could have taken much the same photos whichever brand of 35mm camera he used, I didn't bother to look for this information.
