Whereas most cheap dive computers are quite large, there do exist a few options that are small enough to be worn as a regular watch. Of these, the Genesis Centauri is the very smallest, having a display diameter of just 27mm and a case diameter of 36mm.
It has four buttons and is unique in that rather than having two on each side, it has three on the right hand side and one on the left side.
It features a backlight, air and nitrox modes, a rechargeable battery and a dive app which you can connect to via bluetooth.
However, the app doesn’t currently have the option to export dive logs meaning there is no reasonable way to get your dive log app of the dive story app.
Despite this, the Genesis Centauri is a well praised and popular dive computer with users praising it’s reliability and extremely sleek, compact design.
