The Mako has a 45mm bezel and 22mm lugs and the Megalodon has a 49mm bezel and 24mm lugs. I owned a Meg and loved it, but unfortunately did not care for the size on my 7 3/4" wrist. The Mako size is great. SteVral came out with a 45mm Meg a few years ago, and it was $990 preorder and $1,100 when in stock. These are half the price of that preorder!! And it has the Benarus branding and not the "SteVral" branding on the watch.
