Did you know?⠀
Sapphire Crystal is the favoured material for watch crystals due to its exceptional hardness - 9 on the Mohs scale. ⠀
Here at Bremont we use sapphire crystal because its scratch-resistant properties are superior compared to mineral or acrylic crystals and it is treated with anti-reflective coating.⠀
