Thanks! Do you think its worth switching out the face to a sapphire crystal in a cheaper watch to see if it wears well? Or is that a tough/ expensive thing to do...
That's probably a waste of time and money. You don't know what the quality is of whatever you would be putting into a cheaper watch from an aftermarket supplier.
I've owned and worn Rolex, Vacherons, Cartiers, Audemars Piguets, and the sapphire synthetic crystals have all held up extremely well. In fact, I've never had to replace the crystals in any of them. I wear them all the time. I only take them off if I'm doing projects around the house or something at the gym where I'm concerned it could get knocked against something really hard. Over 20 years ownership of some nice watches, and never seriously damaged any of them.
That is not to say that they can't be chipped or cracked if you whack it against something really hard. My sister chipped the edges of the sapphire synthetic crystal on her Rolex Datejust, as she was pretty careless about what she was doing or what it might come in contact with.
I know some people are concerned about scratching bracelets, but there is no way to avoid that unless you wear long sleeves all the time to cover the watch, and even then if it pops out from under your sleeve and rubs against a desk in can leave marks.
Just get the watch you want and enjoy it.
