Btw there are things called “screws” and they can look cool on a more traditionally male watch or you can put it on the back plate androgynous or female watch. You dont need glue for waterproofing, thats just anti-repair propaganda. Look at every mechanical watch, gshock, garmin, etc they all have screws and 100,200 or even more meters of water resistance.
If the battery, screen, back assembly and maybe the buttons are repairable thats already good for a smartwatch.
