Durability is good unless you wear it as a daily for years. Even the gen will wear in that case, especially on the crown guard with a manual wind. If it's in a rotation and you're careful with your watch, you're good.
Wears well and no discernible difference from gen over time -- worth the buy if you like the look. If you're worried about dings or fading, get a ceramic model -- 292, 431, or 438 -- can't go wrong.
