Ever since I got my Galaxy Watch I wanted to see if it was possible to get Swatch Internet Time (.beats) on the thing.
You must download Watch Face Studio. NOTE: While I used a Samsung Galaxy Watch 7, it should also work with other devices running Wear OS. See Samsung's webpage.
Create a new project and once you're in editor, click on the + button (add element) on the top of the screen. Select "text".
In the properties panel, look for "text field", you should see a box in which you can type things.
Now paste "@(floor((([UTC_TS] + 3600000) % 86400000) / 86400))" into the box (without the quotation marks of course). NOTE: the floor command is used to round it down to integers.
Test if it works with an external source online, such as https://internet-ti.me/converterAdd other stuff with the WYSIWYG if you want and select "run on watch". For more information on how to connect your watch: some random reddit post.
That should be it.
