I only had my smart watch about a month. I ordered it directly from Fossil off the website. The watch failed due to the charging rings on the back coming loose. It appeared that my sweat dissolved the glue that holds the charging rings on. Since it is called a "sport watch" I assumed it would take a little sweat in the summer heat.
It took a significant amount of time to navigate the Fossil website to get a return order. I shipped it by USPS 2-3 day on July 5th. The website says the customer will receive confirmation that the watch has been received within 3 business days. I have not been contacted. I can find no way on the web site to directly track my service order. Everything takes you to a Q&A page that does no good in answering specific questions. As a matter of fact, I can find no way to directly contact anyone!
On the plus side when it worked I really liked it. Generally, I would be around 50% charge by bed time. I did find that when I would sweat, it would discharge very quickly. But, everything functioned well and I was enjoying using it. I particularly liked the google pay feature, as my android phone does not have the feature.
