The function is extremely sensitive to movement and requires you to stay incredibly still. I have often given up without achieving a reading. Also, when it seems to be in a more co-operative mood, the reading provided leads me to question the accuracy . I have had oxygen levels of 88% one minute and (on checking!) 95% the next. One day the watch gave a reading of 81% and the phone at the same time (from the index finger on the other hand) gave a reading of 94%. One of them is wrong, and I suspect the Watch 3. Quite honestly I don't bother any more as it seems so arbitrary.
