scapa
·The bezels are not as easily manipulated as a Planet Ocean, or even other brands for sure. It is one of the gripes I have with the 300M line (along with the lack of taper in the bracelet). However the tapered rubber of the ceramic 300M is really nice. I have that strap on the white 300M and it's my favorite rubber strap.
I agree the PO proportions are a little off on the 39.5, at least to me. The current 43.5mm looks great though!
Yeah, I've tried the PO 39.5 multiple times, and it wears a bit like a tower, just always feels unbalanced on my 7" wrist, despite the quality of the finish and watch as a whole. That ceramic SMP is amazing in person.
I've slowly come round to the SMP Diver's bezel. It works well enough with dive gloves to be usable, although I generally prefer the Pelagos or Doxa 1500 for their greater visibility, and the finishing on that bezel is beautifully-done, a real magnet for light. So it trades a bit of functionality for panache. If it's your only dive and you dive or use the bezel for timing regularly I get it, but using the press-and-turn method it's rarely let me down.
