Digital watch with vibration alarm function, 50M water resistance. I checked it after a while, and the vibration seems weaker than before. I think it might be fixed by replacing the battery, but I'm not sure. (Another TIMERS11 was fixed by battery replacement) If that's okay with you, please purchase it. No returns accepted. - Model Name: TIMERS 11 - Function: Vibration alarm - Water Resistance: WR 50M - Design: Digital display - Color: Black Thank you for viewing.
