Writing for iMore, Greg Koenig provides a fascinating and thorough look into the build quality of the recently released Apple Watch. As anyone who has ever seen an Apple product unveiling can attest, Apple takes a tremendous amount of pride in the materials it uses and the processes it employs to create its products. Indeed, some of Apple's innovations extend beyond consumer electronics to include advanced manufacturing techniques as well.
All that said, it shouldn't come as too much of a surprise that the build quality and durability on the Apple Watch is quite high. Regarding the Apple Watch Sport collection, presumably poised to be the most popular, Koenig writes that Apple opted to go with a 7000 series aluminum alloy, resulting in an extremely hard casing that should make it extremely difficult for users to scratch, dent, or even scuff up even with heavy use.
The Apple Watch is much more durable than you think
