So, I'm pretty infatuated with the SRPD63 but I do think I'll find it a little small for my ~8" wrist. I was thinking about a turtle conversion case like the CT702. I'm fairly sure that this case works with the Seiko 5's but just wanted to double check? And also, is the crown a direct replacement to a screw-down crown? What I mean is, no need to change the dial/date wheel like you would for a 3 o'clock case? Obviously, the turtle and SRPD63 are both 4 o'clock crowns but exactly the same angle?
