I work in many dusty, gritty places, machine shops included. I love my $60 watch, it's been to 4 continents and back for 12yrs now.
Slight chip in the edge of the crystal, some mild scratches too. I'm just happy to not contribute to the waste stream by buying one reliable item, and cherishing it even when it gets a bit beat up.
Do these kind of apple/google watches hold up? How hard is battery replacement?
