The Cressi Donatello is an underwater and freediving  computer. It’s also perfect for other water activities due to the deactivate option of the ‘dive’ functions. This prevents any unnecessary alarms while swimming or snorkelling. It has a high contrast display and the heavy duty case with a steel button is fitted with a bezel. This is made of plastic.

The two-tone wrist band is made of TPU rubber with a stainless steel buckle.

*Battery change -important information*

When you are replacing the battery, do not insert the battery perpendicularly. Instead, keep the tab of the battery holder before tightening the cover.

When it comes to diving it’s important to remember that most people aim for at least twice the dive time on the surface before diving again. So if you dive for 60 seconds then you should aim for a minimum of 2 minutes on the surface before you dive again. As soon as you hit the surface the Cressi Donatello Diving Computer will automatically activate a stopwatch and show you how long you have been top side for.
