Just got this watch. After finally pairing, I love it!!! It does have a flaw. It appears only to be able to link/sync/pair to 1 cel phone at a time. I paired it up with my Android work phone with no issues. Then tried pairing up to my iPhone with no luck. It now did not work with my Android. So, like a previous owner, called Tissot, I also experienced long wait times for Tissot support, only to fix it myself. For the record, it appears, you have to set watch back to factory settings, also uninstall the app on cell and reinstall the app, resign in, and complete the pairing process all over again. It also took a few times for the process to complete.
