Customising my Fitbit Versa has been a fun past time – science, festive and Metal Gear Solid themes have prevailed! If you have a smart watch with a square watch face you might like one of the below watch faces (all free). Nothing fancy just static graphics.
If you want one just open the image from the website and download it. No instructions provided for transferring to your watch as there are many different watch OSes and ways of doing that.
