I'm a fan of sensible sized watches but I have to say, a 36mm diver with a thick sports bezel would likely be too small for me because the sports bezel really shrinks the dial. 35/36mm is more than big enough for an all dial or narrow bezel design. The Rolex OP, Explorer and DJ models for instance are perfect in 36mm but in a diver it's too small. 38mm to 40mm is better in such a sports watch imo.
