Other mechanical watches with precious-metal cases not named above.

Give movement type and case metal; include authenticity papers. Precious metal cases (gold, silver, platinum) also need hallmarking and precious-metal content declarations, and the shipment may require customs valuation by weight and a purity certificate. Watches and clocks are high-value, small and easily pilfered: insure cargo, ship in locked cartons with tamper seals, give movement type, case material and country of origin on the invoice, and check import duty and Swiss-made or hallmark labelling rules in the destination market; battery-powered pieces need lithium or button cell declarations.
