I wanted to add to this thread my recent experience with the SBDC061. I love the Seiko NAFTs (or Turtles), but wanted something more classic to wear at work. I recently picked up another SKX, but after trying other watches along the years, the quality is just not there (the Turtles are by far a better watch). I've always liked the MM300 but after reading so many issues with the fit (and the long links on the bracelet), I wont get one before trying one in the flesh. Long story short, I chose the SBDC061 as my first "mid tier" watch thanks to the comments and pictures on this thread:
As stated before, the diameter of the bezel is around 41mm, plus the case sides are cut similarly to the Turtles, which make the watch look and feel smaller on the wrist (note how the case hugs the bezel, pretty nice):
The bracelet is very nice, love the polished edges on the central links and the fact that the end links are permanently fixed to the bracelet (and hate that they are not fixed in my BB58 bracelet). In my opinion, bracelets look better this way:
The lugs curved down and along with the placement of the springbars, the watch wears great on natos, even on my 6.75" wrist. This is something I was not expecting due to the long lug to lug distance. Definitely tells you a lot about watch specs vs. case design. It also helps that it is a relatively thin dive watch:
As mentioned by Matt (smalls), not a fan on the long clasp with the diver extension, but its not uncomfortable on me. I don't love the look of the MM300 clasp, so I ordered the ratchet clasp from Strapcode, which will probably be too big but I want to try it anyways. Someone needs to make a ratchet strap similar to the Omega one. Good thing is that the diver extension pivots like a regular link, so after some trial and error, I found a way to wear it comfortably:
The case is very nice for the price, from the side, it looks more interesting that the case on the BB58. Brushing is not as nice as my PO (and it shouldn't be do to the price difference). Some chamfers would have been nice. The bezel insert is very nice and shiny (not sure of the material, but my guess is some lacquer paint). The dial is a nice dark gray matte color, similar to the one on the PO 2500. To my eyes, everything lines up. Love that Seiko went with date only, which looks rather nice in white thanks to the white outline on the date window. Lume plots look great too and I find myself digging the hands. The coin edge bezel also makes the watch look dressier, which is a plus for me. All in all, it looks great in the office as it does outside.
I like the watch so much, that I which Seiko would made a version with the 8L35 movement, signed crown and a better clasp. All in all, great watch for the money. And the SBDC065 "Great Blue Hole" version (awful name) looks rather nice too.
Bought the watch from Gnomon Watches, with free shipping. Ordered Thursday and had it the next Monday (from Singapore to Puerto Rico).
