Warranty & Authenticity
Each watch is supplied in its original brand presentation with its unique serial number, original box, warranty card, and applicable manufacturer documentation. The warranty card is activated before the watch is offered for purchase, so no additional registration or activation is required after checkout or after delivery.
Model reference, serial number, and warranty status can be verified at any time through the relevant brand’s available verification channels. Every watch is also inspected by VOLICES before dispatch for authenticity, condition, and package completeness.
In addition to the applicable manufacturer warranty, VOLICES provides a complimentary 1-year limited store warranty for qualifying mechanical or manufacturing defects, subject to our warranty terms. This additional coverage does not replace or limit any manufacturer warranty that may apply.
