What is the Radiant Automatic made of?

Updated 28 Sep 2026
Short answerThe case is made of surgical-grade brushed 316L stainless steel. The dial is protected by a sapphire crystal with 3 inner anti-reflective coatings.

Case: It is made of surgical-grade brushed 316L stainless steel. This is a hypoallergenic material, resistant to corrosion and scratches, commonly used in premium watchmaking.

Crystal: The dial is protected by a sapphire crystal with 3 inner anti-reflective coatings. Sapphire is one of the hardest materials in the world (second only to diamond), which makes it virtually scratch-proof in everyday use.
