Product Description
Synthetic sapphire, a material nearly as hard as diamond, has been utilized in watchmaking for decades due to its exceptional scratch resistance. While challenging to work with because of its extreme toughness, advanced cutting techniques enable the creation of diverse shapes from traditional round cases to tonneau, square, and even complex designs resembling automotive engines or aircraft components.
