Disclaimer

Please note: Watches are sold "as is" and without any warranty, particularly regarding their mechanical operation, accuracy, or the longevity of their movement.

Most watches have been opened by our specialists to examine the type, authenticity, and quality of the movement. Consequently, water resistance is no longer guaranteed. Furthermore, some watches are of such an age and condition that a service is necessary; buyers are therefore advised to consult a watchmaker at their own expense, if possible before the sale, to obtain an estimate and bid accordingly.

All watches presented may have undergone prior servicing or restoration during their lifetime. As a result, they may contain non-original parts such as hands, crowns, or internal movement components, etc.

Any information in our possession regarding restoration, damage, gem-setting, or overall condition is provided for information purposes only. It represents the expression of an opinion at the date of cataloguing but does not constitute a guarantee. It does not engage the liability of HDV Hôtel des Ventes SA or its employees. Photographs and dimensions are provided for guidance only.

As the pre-sale exhibition allows buyers to examine all lots prior to bidding, no claims will be accepted once the hammer has fallen (art. 6 of the General Terms and Conditions printed in the catalogue and available on Piguet.com).
