I had heart palpitation issue n one day when my heart rate suddenly spike to over 170 the watch showed 80 n then 90 to 96 even i did a manual measure after the continous measure heart rate function didnt pick it up! I had to use my omron machine which accurately showed 178 beats while Watch 6 on my wrist even after few round of measuring showed 96 or 97 at the same time. Only 20mins later after i was in the car rushing to a&e hospital, the watch then showed 174 beats for very short while n the dropped. Its all captured on my watch app and i can prove it. In a&e , my heart beat was still over 170 from a&e machines but this watch 6 still showed below 100. I showed to healthcare professional too.
Even the free HPB watch from health promotion board do better than the expensive Watch 6! So those who rely on Galaxy Watch beware n check with other devices for your iwn health safety.
Critical health data dont seem to be accurate. So please be aware. There are serious issue with Watch 6. I own watch 6 for less than 1 mth and its in perfect condition externally. Internally i think Samung watch 6 has manufacturing issues, making not accurate for people who buy it for monitoring health data. Be Aware.
In case Samsung claimed i didnt wear tge watch properly or snugly tats not true. It sat securely on my wrist. I even tried to adjust it a few times but the critical health data in heart beat was still grossly erronous! So watch 6 to me now is just an expensive watch to tell time n other non critical information. It totally failed for health data which i bought the watch for.
