Check that notifications appear on your phone first, then enable the relevant notification settings in the watch companion app and phone permissions. Follow your model's manual for reconnection steps.

Terms vary by model. The A03 manual states one year for the motherboard and six months for the battery and charger; the MA20 manual describes a 12-month workmanship warranty with exclusions. Check your supplied documentation and contact the seller with proof of purchase.
