• Common Symptoms: Watch stops, intermittent display, weak beeps, or the device will not power on.
• Visible/Sensory Cues: Fading display, slow or stopped hands, reset prompts, or low-battery warnings.

Pro Tip: Match the number on the old battery exactly and install with the correct polarity because button cells that look similar are not always interchangeable.
