Casio offers a manufacturer’s warranty, which can be requested directly through their customer service team. For any service or warranty inquiries, it’s recommended to contact Casio support through official channels.
While the watch is built for durability and everyday wear, it’s advisable to avoid prolonged exposure to extreme temperatures, moisture beyond typical conditions, or physical impacts that could compromise its function. As part of Casio’s trusted lineup of functional watches, the AEQ-120W holds a solid position in the men’s wrist watch category, reflecting its balance of practicality and reliability.
