Care & Maintenance Recommendations

To preserve performance and longevity, rinse the watch with fresh water after saltwater exposure and wipe dry thoroughly. Avoid exposing the crown to moisture unless adjusting time or date. Periodically clean the bracelet links with a soft brush and mild soap to prevent grime buildup. Although the sapphire crystal resists scratches well, prolonged contact with abrasive surfaces may still cause wear over time. Store the watch in a cool, dry place away from direct sunlight when not in use.
