The warranty is valid 12 months from the date of the purchase. The warranty covers manufacturing errors, not normal wear and tear. It is not valid if the damage is caused by incorrect usage and/or accidents.
For any watch purchases, the warranty doesn't cover normal wear and tear, the battery, the strap, loss or theft. Marc Ocean won't accept any warranty claim if the watch shows signs of excessive use or misuse.
Make sure you contact the customer service team as soon as the manufacturing error has been discovered. When contacting the customer service, please specify your name, address, order number and a detailed description of the issue at hand. We also need a photo clearly showing the defect.
