its funny that I saw this post, I just came to post a very similar request. I have the 635-7613-4174RS Oris Williams F1 day date w/ rubber strap. I have never been a big fan of rubber straps and prefer a steel. That would basically make it like the 635-7613-4174MB model. My brother has the 635-7613-4164MB and I have always liked the design, sporty but not too crazy, but at the same time, has just enough detail to not be boring. I didn't want to get the exact same one, and the 4174RS popped up and I had to buy it and worry about finding a steel bracelet later. Problem is, you cant even go and buy a high quality bracelet and slap it on, because the design and attachment points are so different. Ours are gen Oris's but maybe a replica strap would work.
