Water damage in huawei watch gt

Hi.I bought a huawei watch gt from an official retailer of huawei.The watch was operating correctly until i went for swimming with this.After that i realised that the watch turned off and couldn’t work but the most ridicilous thing is that there were no screws so the water caused damage to the overall device.What can i do now?The device is dry and can not work.Is there anything that can i do with replacing the parts?
