Thank you! Really interesting question and one that I hadn't considered. They are such different watches in terms of design, finish, price point, function, and versatility. The 15202 has an amazing finish, and so many complex angles, beveled edges, and contrasting finishes that after wearing it for a while you begin to really understand why it costs what it does and why its production is quite limited. It it is also their only time only movement that is assembled and finished in the same department as the high complications. Its very versatile, and I could wear it for everything other than the dressiest of functions when I might wear a true dress watch, or if I were going swimming (you can, its wr to 50 m, but I don't wear watches in this price range for swimming). There really isn't anything I dislike, would change, and there isn't any competitor or other watch that I had second thoughts about. I know there are lots of Nautilus fans out there, and I'm a big fan of both the 5711/a and the 5712/a. Those are exceptionally well finished, but for me those are pieces I would consider adding to compliment my collection. I wouldn't choose either of them over a 15202...I just prefer the 15202s design far more (but that is subjective). For me the 15202 gets more wrist time than almost any of my other watches combined. I really like dress watches on straps, but I just don't tend to wear them very often. Sports watches or luxury sport watches tend to fit my lifestyle more than pure dress watches do. As for the BLNR, its my favorite modern Rolex. For years the Daytona was my favorite, and if you talk with people who service watches and study movements they will tell you the cal 4130, which powers the modern Daytona is technically a fantastic movement. Even beyond the technical aspects of its movement, IMHO its probably the best chronograph available brand new for under $20K. That said, I really enjoy wearing the BLNR even more than my modern Daytona. So in a sense in terms of my favorite modern Rolex it has dethroned the Daytona in the hierarchy of my collection. I do qualify it in terms of saying modern Rolex watches, because I think if I could keep only one of my Rolex watches it would be my vintage 16520 Daytona. I like my BLNR so much that from time to time I have considered adding a 16710 Pepsi. That being said, the BLNR does not get as much wrist time as my 15202 so maybe that is a sign that there is still a greater satisfaction/enjoyment level with the RO. The BLNR looks great, is really well finished, has the practicality of a date, an additional timezone, its water resistant to 100m, and its bezel is scratch resistant...but it can't go quite as far in terms of dressing it up. Yes, I know Bond wore Subs and now Seamasters with suits and tuxedos...but the 15202 is better suited for that if I'm trying to wear a sports watch with dressier attire. So after thinking about it, the 15202 still reigns supreme in terms of satisfaction, but the BLNR runs a good second place for a less expensive pure sports watch. Cheers! It really depends on your taste and what you are looking for, pure sports watch, dress watch, something in between. Also, if you consider pre-owned there may be other brands or designs to consider.
