Friendly Reminder 1.Water Exposure Avoid contact with hot water or steam (e.g.， hot springs， saunas)， as heat can compromise water resistance. 2.Temperature Extremes Minimize use in environments with sudden temperature changes， which may cause condensation inside the watch. 3.Magnetic Fields Do not place the watch near strong magnetic sources (e.g.， TVs， speakers， phones) for extended periods， as this can magnetize the movement. 4.Chemicals & Cosmetics Avoid direct contact with solvents， perfumes， or cosmetics， which may damage the case， bezel， or strap. 5.Physical Impact Refrain from wearing during high-intensity activities (e.g.， sports， manual labor) to prevent scratches or internal damage. 6.Strap Adjustment New straps may feel stiff initially; gently flex them before wearing or allow a few days of wear to soften naturally.
