I know watch protection is a polarising subject. It’s clear what side I’m on…
Generally outside this latest trend of taking close up pics and posting on the internet it’s hardly visible. The trade of to having a mint unmarked watch is worth it IMHO. Many years of watch abuse have won me over.
Do you have a case for your mobile phone? Wrap or polish your car? Oil / wax your wood furniture. For me it’s the same. But appreciate each to their own 👌
