Everyday watch care
Rubber strap care
- Under normal use, PICONO rubber straps typically last about 18 months. Actual life depends on usage, frequency, and environment.
- Do not clean rubber straps with acetone or strong solvents. For light dirt, use an eraser or a soft cloth with a small amount of soapy water, then wipe with a damp cloth and air-dry away from direct heat.
Metal bracelet care
- If you wear a metal bracelet often in sweat or water, it may tarnish or corrode. Clean with a soft cloth and a little soapy water; for heavy dirt, use a soft brush, then wipe with a damp cloth and dry thoroughly so moisture does not remain between links.
Leather strap care
- Do not soak leather straps in water or salt water. If you are often in water for long periods, consider a rubber strap or stainless steel bracelet instead of leather.
- Leather may darken slightly over time with wear—this is normal.
Stainless steel case care
- Stainless steel resists many chemicals, but sweat or prolonged water exposure can still cause corrosion. Every 1–2 months under normal use, wipe with a soft cloth and a little soapy water; for heavy dirt, use a soft toothbrush, rinse with a damp cloth, and dry the case, crystal, crown, and gaps thoroughly.
Water-resistant gaskets
- PICONO watches use gaskets to help maintain water resistance. Gaskets age with use, and water resistance may decrease over time.
- After swimming or water exposure, rinse with fresh water or wipe with a soft cloth and mild soap as needed; dry the case, crystal, and crown thoroughly. Salt water and pool chemicals can accelerate gasket wear—forced use when gaskets are worn may lead to water ingress and movement damage.
Water resistance
- Water resistance depends on gaskets at the crystal, case back, and crown. PICONO case backs marked “WATER RESISTANT” are tested to meet ISO 22810 where applicable.
- 3 ATM (30 m): Suitable for daily wear and light rain; not for immersion.
- 5 ATM (50 m): Suitable for swimming and general household use; follow product instructions for immersion limits.
- 10 ATM (100 m): Suitable for swimming and many water sports per product rating.
Screw-down case backs
PICONO screw-down case backs are designed for a secure seal. Slight misalignment of text and case is normal for this construction. If that is unacceptable, please do not purchase.
