Glass screens cracking due to abuse and drops and force applied the screen is normal, However, Apple themselves claim that the screens of their watches can crack without even touching the watch. This means that the displays are prone to cracking due to a design flaw. This is not the first time the company has accepted to have design flaws in their products.
Apple also claims that only the Apple Watch Series 2 and Series 3 are affected and the rest of the Apple Watch generations i.e. Series 1 and Series 4 are unaffected by this issue. Considering Apple Watch is one of the best selling smartwatches right now, this issue can affect probably hundreds of thousands of watches.
The glass repair costs $229 to $289 for regular variants with the Hermès variants costing $329 and the ceramic variant costing $800 for the glass repair. With repair costs so high and design flaw, many of the users are excepted to be mad at Apple. However, Apple also said that an Apple store or an Apple-authorized service provider will replace the screen on eligible units that exhibit this type of crack, free of charge so that the users do not have to suffer.
