Aclock on an actual watch!
Using Termux and the regular unix ncurses.

Had to downgrade Termux so the bottom bar could be hidden.

hahaha thats epic! thanks! can you tell more what watch is it, what os is running? did you make a special build or port?
Galaxy Watch 4 Classic
Runs Android
Using Termux as the terminal emulator https://termux.dev/en/
Compiled the standard UNIX Ncurses build with clang on the device itself.
i think termux build is gonna work on any typical android environment in any terminal emulator
however i doubt that you have to offer another arm android build as Android +5.0 prevent its exceute due to a missing flag while building
"../binaries/arm/aclock-arm-android4": error: Android 5.0 and later only support position-independent executables (-fPIE).
clang provided with termux results a working binary in the same device
