Important Notes
While built for extreme conditions, the watch should be rinsed with fresh water after exposure to saltwater or chemicals to maintain performance and appearance. The black PU strap may show signs of wear over time with frequent use in wet environments, but can be replaced if needed. Warranty information is available through the manufacturer—customers are encouraged to review the provided warranty details for coverage specifics. This watch is designed for men and may not be suitable for individuals with very small wrists due to its 45mm case diameter. Always ensure the crown is fully screwed down before submersion to maintain water resistance.
