Cressi Leonardo Dive Computer Review

I have been a scuba diver for about five years now and have always been interested in diving watches. I have never been able to afford one until now. When I saw that Cressi was offering their Leonardo Diving Computer for under $300, I knew that it had to be mine!

I bought the Leonardo from Amazon, which had the best shipping price. I ordered it on Thursday and it arrived on Monday. The packaging was solid and no damage occurred during shipping.

The Leonardo is very easy to set up and use. It comes with a manual that explains everything you need to know about using this computer, but if you don’t want to read through all of that information then there is also an app available on Google Play that has videos showing how each feature works (this is what I recommend doing).

The screen size is perfect for me; it’s not too small or too big so it doesn’t take up too much space on my wrist which is important when diving because you need as much room as possible so nothing gets tangled up with any equipment attached underneath your suit jacket or vest layers which could cause problems later down below water level!

Modes of Cressi Leonardo Divign Watch

Cressi Leonardo Underwater Single Button Diving Computer Watch offers you three modes:

  • Air
  • Nitrox (21-50%)
  • Gauge

This device has a depth gauge, so you can easily keep track of how deep you are while diving

It comes with an automatic altitude adjustment feature that automatically adjusts for any changes in water pressure at varying depths. This makes it perfect for scuba diving anywhere in the world!

The software and operating system can upgrade whenever any new release is there. You can upgrade easily by connecting your device with a laptop/computer via USB cable.

Easy to Use

It’s so easy to use, and it’s really accurate. You can even set up a dive plan before you go into the water! It has a backlight, so you can still see it in the dark, and it has an alarm that goes off if your oxygen level is getting low.

You don’t have to worry about setting anything up before you go diving, just turn it on and go! The buttons are simple and easy to press with gloves on (which is something I’ve found can be difficult for some other computers), so even if you’re wearing winter gear during your dive, you won’t have any trouble using it.

Cressi Leonardo Dive Computer Accuracy

This scuba watch is incredibly accurate. Each dive has an average error of less than 1 percent! That means no more worrying about whether your depth or time calculations are correct—just focus on enjoying yourself and exploring underwater worlds.

There’s also a feature where you can program in two different depths: one depth for when you are diving down deep and another depth for when you’re going up shallowly (so it doesn’t start beeping at all). That way, if your friend is below you but still within reachable distance, they won’t get startled by an alarm going off when they aren’t going deeper than their set safety limit yet


This Cressi Leonardo dive watch is constructed with simplicity in mind, it has only one button that you can use to navigate through all of its functions, making it easier than ever before to find out information about your dive while you’re on the surface or underwater. Plus, there are several alarms built into this device so that you don’t have any accidents while exploring underwater terrain!


It is designed to be used by divers who are new to diving or have limited experience with diving equipment, as well as more experienced divers who want a simple device with few bells and whistles. The device can be used with any kind of diving gear, including scuba tanks, various types of snorkeling equipment, and even surface-supplied diving helmets. It has a sleek design, but it’s also very durable, so you can take it with you wherever you go
