Fitness watch

I found my old inexpensive Letsfit Fitness Tracker, Activity Tracker Watch, I purchased in 2019. Charged it but date/time was wrong. Needed phone app to set date. App want’s logon info which I don’t have and it wasn’t required when I got it, otherwise it would be in my password manager. No…that was for the letsfit app whatever that is. I needed the veryfitpro app. had to unpair/repair then it worked…date set! However for some reason part of the strap below left was broken off and it’s very short. I only see watch band replacements for different models. I can buy a new updated Fitness watch for around $35. GPS would be nice…but not available in budget fitness watches.
