Rolex Datejust 31mm 278278-0049 Watch

1. Cleaning & Maintenance

• Metal Bracelet/Case:
  Gently scrub crevices with a soft-bristled toothbrush dipped in lukewarm water (neutral soap optional). Dry thoroughly with a microfiber cloth.
• Leather Strap:
  Avoid moisture exposure. Wipe sweat or dirt with a dry cloth to prevent hardening or cracking. Allow straps to air-dry naturally and rotate usage to prolong lifespan.

2. Environmental Protection

• Temperature:
  Avoid extreme heat (saunas, direct sunlight) or cold, which may cause lubricants to dry out or components to deform.
• Magnetism:
  While equipped with anti-magnetic materials, keep timepieces away from strong magnetic fields (e.g., speakers, MRI devices).
• Chemicals:
  Prevent contact with perfumes, solvents, cosmetics, or corrosive substances to avoid damaging precious metal finishes, rubber seals, or coatings.

3. Water Resistance Care
All timepieces feature water resistance under specific conditions, but are not fully waterproof. Avoid exposure to pressurized water, hot water (e.g., showers, saunas), and submersion activities. After water contact, rinse with fresh water and dry immediately.

4. Winding & Power Reserve

• Automatic Movements:
  Regular wear provides sufficient power. For long-term storage, manually wind the crown 20-30 turns monthly to maintain lubrication.
• Manual Winding:
  Stop immediately if excessive resistance is felt to prevent mainspring damage.
