If you go to buy the latest Apple Watch, you will typically be presented with the series 6 or SE options. It is worth thinking before you go to purchase your watch, what it is exactly you want to use it for and the features you wish to benefit from – this will help you choose the best option for you.
In essence, these two models are very similar. They both run from the latest watchOS 7 software and have GPS built in – the benefit of this is so you can go out running or even just out and about knowing you will still get the accurate fitness stats you want. They both have good bright screens and are water resistant upto 50m.
