Important Notes

Please note that product warranty details are available separately and should be reviewed prior to purchase. The watch is designed for men and may not be suitable for smaller wrist sizes due to its 41 mm case diameter. While water-resistant to 200 meters, it is recommended to avoid exposure to extreme temperature changes or harsh chemicals to maintain longevity. Care should be taken to clean the leather band regularly and avoid prolonged exposure to moisture to preserve its appearance and durability.
