warranty_period | When covered under the manufacturer’s warranty it is possible to get a replacement in the case of a malfunction.

waterproof_depth_rating | The waterproof depth rating indicates how well the device is protected against water ingress and water pressure. Devices that can withstand more water pressure are better for swimming or diving.
