You can operate the device easily, by pressing the screen with your fingers.
The waterproof depth rating indicates how well the device is protected against water ingress and water pressure. Devices which can withstand more water pressure are better for swimming or diving.
The watch band is removable and can be replaced by any standard watch band of the correct size, allowing you to customise it to your liking.

The bigger the screen size is, the better the user experience.
