    Ships from Duxbury, United States

    Tariff-free

    No import duties for American buyers

    This brand assembles in the US — watches ship tariff-free to domestic addresses.

    5% of profits donated to coastal community organizations like the Cape Cod Commercial Fishermans Alliance.

    No import duty on domestically assembled watches. Brands like TSAO Baltimore, Nodus, Vaer, and Vortic ship tariff-free to US buyers.

    Tariffs are assessed based on where the watch is assembled, not where individual components originate. A watch with a Japanese movement assembled in the US incurs no import duty.
