I would wholeheartedly agree with the no-cyclops crystal and would do it in a flash. The PVD...less so. The first time you get a rub mark (let alone a dink) you'll be cursing the finish. I find aftermarket PVD especially to be a bit of a crapshoot at best.
If it was mine I would go for the crystal swap and treat it to a new strap to keep the look fresh :)
ps I really like the watch :)
