i have gshock gwn-q1000 quad sensor gulfmaster. the other day i bumped the glass on a door knob. a few days later it loked like a scratch but i noticed something in the glass. it doesn't have a feeling like a surface scratch but then again its super small so i might not be able to really feel it. you can really only notice it at the right angle in the light. i do go free diving with it and surf with it. should i pay to have the glass replaced or am i worrying about nothing? seems like an insignificant crack to me cause its super hard to see.
