Im considering to buy the apple watch ultra 4, and am not sure because I read that the back is made from ceramic & zirconia.
compared to earlier models where it was ceramic and saphire crystal.
what Im wondering is what part is made of zirconia & ceramic, is it just the back of the watch or is it also the part that covers the sensors?
because chatgpt told me that its just the back part, but the part that covers the sensors is still saphire crystal.
does anyone know the answer?
if zirconia covers the sensors then I rather not buy, because zirconia can get clouded over the years which makes the sensors less accurate.
