I am currently using the Fossil Gen 6 Hybrids and I love them! They are currently working fine, and I would like to have the new Pebble in the future. However, I don’t like the square design - I would much rather have something like Pebble Time Round 2.

You can use an open source app like Gadgetbridge to connect it to your phone without any online services - if this is what you ask for. The only online service is the app store - which you don’t have to use (you can locally upload any app you want).
