Concluding Thoughts:

All the Watches, as mentioned earlier, are excellent. The Apple Watch SE is the best value for money with a large display and offers almost all essential features. The display on Series 3 has larger bezels, and I would personally spend a little extra and get the Apple Watch SE.

If you have a higher budget, the latest Series 7 is an excellent choice with features like ECG, SPO2, and always on display – it is the best a man or woman can buy.

So, that’s all from our side; please ask in the comments below if you have any questions.
