There are 40mm and 36mm variants; some patterns available in only one of the sizes. Frankly even the 40mm model is optically small thanks to its understated design; it's got two rather unobtrusive complications, and one side button. The maximum thickness is significant, but the back side is convex and the rim is reasonably thin, so against your arm it looks about the same as an average self-winder. FWIW, I'm very happy with an alternative wristband - the black/gray silicone one which normally goes with Sapphire version.
