It's tough too, as you'd expect from a G-Shock watch, with a titanium case back and titanium carbide finish to prevent scuffs and corrosion. It's water resistant to 200m (impressive since most smartwatches are only rated to 50m), which makes it suitable for not only swimming, but also water sports like surfing.
Casio has yet to confirm a release date for the G-Squad Pro (you can register for email updates (opens in new tab) when it becomes available), but we do know that it will cost £599 (around $830 / AU$1,000) at launch. That's a lot.
That launch price will make it more expensive than the top-end Garmin Fenix 6 and the super-tough Polar Grit X, both of which place highly in our roundup of the best running watches. Both are built to last, and feature advanced hardware and training tools to help improve you
The key difference is that both of these watches – while packed with advanced workout features – are limited in terms of third-party app compatibility. The Fenix 6 supports apps downloaded via Garmin Connect IQ, and the Polar Flow app allows you to customize the widgets on your Grit X, you can't download third-party tools.

In the meantime, if you're in the market for a Wear OS sports watch, take a look at the Fossil Sport, which currently sits at the top of our list of the best Wear OS watches, is powerful and lightweight, with impressive battery life and a gym-focused design. It's also a fraction of the price of the G-Squad Pro, currently selling for around $250 / £150 / AU$230.
