That's pretty easy. We'll send you an insured FedEx overnight label. Wrap your watch in something super protective such as bubble wrap or some padded material and then place that box inside a bigger box with some padding such as newspapers, folded up cardboard or anything that can keep the smaller box stable.
You can also take your watch to your nearest FedEx store and ask them to pack it securely. For security purposes, do not disclose the contents or value of this shipment when dropping off your package at the FedEx store.
