In 100 years of luxury horology sales, no manufacturer has ever considered a offering case for their $1000-$100,000+ watches, and apparently no consumer has ever expressed interest in one.
And I'm talking about hand made gold and platinum mechanical watches, whose cases, dials, and movements are far costlier to replace or repair than any mass produced $600 digital watch.
Only Apple customers would even think of destroying the subtle curves and lines that Ive & Co. struggled to perfect, by covering it in a case.
And only Apple customers would attempt to blame Apple for their carelessness.
I've seen several threads questioning the durability of the watch due to obvious negligence on the part of the wearer. But I have never seen anyone demand a free Swiss watch because they scratched it, on any of the watch forums I've visited over the years.
A cell phone case I get. You need a phone. If you drop it and it breaks, you have no communication.
No one needs an Apple watch. Or a Patek Philippe, Rolex, Omega, etc, No one needs a wrist watch at all, which is why no one makes a protective case.
To anyone considering a case for a wrist watch, stop and ask yourself why. Is it because you can't afford to replace it if it gets damaged? Then you've probably spent beyond your means by buying the watch in the first place.
Are you trying to protect your "investment"? Unless you never open the box and keep it in a safe for 50 years, a $600 Apple watch is in no way an "investment". Buy $600 worth of Apple stock if you are looking for an investment.
Do what owners of $10,000 watches do. Either learn to be more mindful of the device on your wrist, or learn to live with a few nicks and scratches.
If I showed you my 5 year old $6000 Swiss dive watch, you would think I bought it last month, because I am CAREFUL with it.
Buy a case for your digital Chinese watch if you must, but just know that this is yet another of the many reasons people hate Apple fans.
