GARMIN ENDURO SCREEN DIAMETER FOR SCREEN PROTECTOR?

Hi, I just bought a Garmin Enduro (1) and I am waiting to arrive. It will take 2-3 weeks so I want to buy a screen protector too. Anyone can tell me the exact diameter (in milimiters) please? I can find the screen dimension on Garmin site but the glass is a little bigger than the screen... and I can not find this information ... even tried chat gpt with no reliable results. Thanks!
