Finally, a watch that does it all. Finally, a manufacturer has a product that allows us to enjoy the world above and below the water. It's a great watch that offers full smartwatch capabilities and getting notifications to my watch from my phone is a fantastic bonus. The main reason I want a watch like this is that I wanted something that allowed me to utilise it for land based and underwater applications. I need navigation, and GPS positioning for work and when out recreationally in the outdoors - now i can use the same tool when in the water. Not only is it now my primary computer when diving but its also a great looking piece to wear for any occasion and thanks to the easy band interchangeability i can even dress it up. And to think... just before finding out about this I was looking to get a Tag Heuer. Great brand, but nowhere near the same functionality as this Descent MK1. Ideal to be your everyday carry and with full functionality both above and below the water.
