Is there a countdown timer?

When you are on the main interface of the watch, press the side button to enter the function interface. Scroll through the options until you find “Timer” and tap on it. In the timer interface, you can set the desired duration for your countdown. Once you have set the timer, tap the right icon to start the countdown. The watch will vibrate to remind you when the countdown timer reaches zero, ensuring you don’t miss any important timing events.
