Customized chips for stopwatch timing, combined with built-in speakers, linear motors, and other tools, provide a multifunctional and user-friendly tool for precise timing.

To use a stopwatch, consult your user’s manual for specific phrases. These include cumulative split, lap split, countdown mode, and recall. A cumulative split is a time recorded while running the stopwatch, while a lap split measures the time frame between cumulative split times. Countdown mode is a preset time for workouts or tasks, while recall displays past splits.
