It was a TTF. It works totally fine on my Gear S3 Frontier.
I have not tried a different font yet as I dont have a quick back and forth with them to test. I'm waiting to see if a re-sync worked and to find out what watch they have.
Figured I'd put it up in here in the meantime 'cause you guys know all the things lol. Actually gonna check to make sure I dont have any effects on the text. Pretty sure i dont but gonna look. Thanks for your help everyone!
