Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
Hi, my watch just arrived today, I was excited to take it out of the box, but very disappointed to find it is not working at all. I will try to find a watch shop that's open, hopefully it's just the battery and they can help me to replace it. At this stage, I cannot recommend the product or store at all.
