About Stainless Steel 316 

Stainless steel 316 is highly resistant to corrosion but not completely rust-proof.
 Wipe the watch with a soft cloth after exposure to sweat, salt, or water.
 Avoid bleach, detergent, perfume, hairspray, and other strong chemicals.
 Store separately to prevent scratches from other metals.
 Although hypoallergenic, discontinue use if skin irritation occurs.
 Rust, discoloration, and allergic reactions are not covered by warranty. 

About the Glass 

Sapphire glass is scratch-resistant, but it can crack under sudden impact or pressure.
 Handle the watch carefully. 

Band Adjustment 

Adjustment by a professional watch shop is recommended.
 If you are unsure about adjusting the links, please consult a specialist.
