Case made of
stainless steel SUS316L
Knot uses SUS316L – a high-purity, corrosion-resistant, stainless steel used for medical scalpels – as standard. This material is pleasing to wear even for those with metal allergies, as it produces almost no metal ions.
※This does not exclude the possibility that an allergic reaction could still be experienced by some people.
Sapphire glass crystal is made of the same composition as sapphire gemstone. All Knot watches are created using scratch-resistant sapphire glass which measures 9 on the Mohs Hardness Scale, second only to diamond which is rated 10. In addition, mechanical models are coated with a single-sided anti-reflective coating.
