We do not guarantee its future operation. It has not been tested over a long period and we therefore cannot guarantee the accuracy of the movement or the power reserve. Services or restorations may have been carried out on the entire watch, resulting in the replacement of parts that may not be original (dial, hands, parts of the movement, bracelet, etc.). As the watch has been opened, we cannot guarantee that it is water-resistant. Unless otherwise stated, we have no information on the last service performed and we advise you to have the part serviced.
