Not enough information for a duty figure
The fields above are reported facts. None of them establishes customs origin: that depends on the watch's tariff classification and a substantial-transformation analysis, and what you actually pay also depends on the seller's shipping and duty-payment terms. Ask the seller for the country of origin and whether duties are collected at checkout, and confirm rates against official sources.
