is that a battery meter designed to look like a fuel gauge on the phone?
With very few exceptions, all high end watches use a movement that does not require a battery. At a very very high level you can do with with an "Automatic" style which uses a weighted wheel to spin around and charge up the mainspring as you move your arm/watch. Or you can use a "Manual wind" to physically spin the crown and charge up the watch for a given amount of time.
From there watches can have different complications. This is just a fancy word for features like a moving second hand, power reserve meter, chronograph, etc. The gauge on my watch is a power reserve so I know how much power is left before I need to wind it again. If I don't, the watch will just stop and I will have to reset the time and charge it up again.
Here is an introduction and there are some cool videos/channels that get into the nitty gritty of how and why brands create their watches.
