Our warranty is valid for two years from the date of purchase. This warranty covers manufacturing defects regarding the case of the watch (defective part or incorrect assembly). Wristbands are not supported. Any repair work must be done by a Millow authorized repairer or we will release all responsibility from ourselves and cancel the free scheduled service. Your warranty will not be valid if you do not have proof of purchase. For more information, please contact our customer service by email: hello@millowwatch.com.
