The Samsung Galaxy Watch 4 and the Watch 4 Classic are similar in design, but the Classic model is slightly bulkier and larger and also offers a rotating bezel, while the standard model is available in more colours and has a sportier design. Unfortunately, however, we can't give any reports on usage, as we were never able to test the devices in such a form. I'll be happy to post it in the community though, maybe a user can help you out.
