In the past, I have bought one watch from Germany before, and it was on a SS bracelet. No issues, delivered in three days, FedEx was great, $25 duty fee.
For my next aquisition: This would be a watch imported from outside the US with a Croc strap. From the searching I have done here, and on US customs website - Croc seems to be a red flag. Shipping it separately or excluding it from the shipment might also be a red flag.
For those that have done this transaction: Please tell me what I need to know about any additional fees or charges with the watch & issues / recommendations about croc strap before I go this route.
