    Perfect

    The Apple Watch Series 12 is a fantastic device. I really love the new health sensors that track heart rate every few seconds and the daily readiness score. The performance is super smooth thanks to the S11 chip, and the screen is bright and clear. While the battery still lasts about a day, the fast-charging feature makes it super easy to top up. Overall, it's an excellent and reliable smartwatch.

    Apple Watch Series 12 (GPS+ Cellular) 46 mm Titani

    Love it ! Good for regulate AFib issues and heart rate and also love it for monitoring exercises! This is my 5th Apple Watch, not because they wear out, but because I love the health options! Also if you fall, it calms EMS and your emergency contacts to alert them! This watch saved my 93 year old father’s life when he took a bad fall !

    I like the longer battery and that it’s thinner than my previous apple watch. I really enjoy the watch.
