So I took a little spill with my Bathys 100F PVD black and gouged a lug and chipped the pvd off the edge. I know the watch is stainless steel underneath, but should I be worrying about corrosion? I'm not sure if scraped stainless has the same rust resistance. Is there an easy way to touch that up? I'm sure many WUS alum have unfortunately dinged their pvd watch at one time. It's not too noticeable so if there isn't a problem, I can live with it. Thanks.
