I wouldn't waste your time with a half ass product. I've done quite a bit if research into this. I find Garmin to have the best overall watches with a good privacy policy last I looked. Make fake account and log no important info in that matches you such as age leave blank and other main identifiers. Even obscure gender if you want. Opt for a watch that has no microphone and disable gps if you want. Check out the Garmin tactix 7 I believe us their current. Ability to completely wipe the watch with a button. Stealth mode with no wireless connectivity for military. Its very legit in how it operates. 28 day battery life even longer if you get the solar glass.

Shop second hand for price reduction. Their warranty is second to none, don't like that color they change it, don't like the band they'll send you any bands you want, have an issue, total replacement, they even let you keep the original until the new one arrives so your not out anything. Not a shill just a no frills company from my experience.
