The Watch House Certificate™ standardizes the certification of a watch and certifies its condition and authenticity. In detail, it is a digital passport that, after expert assessment, guarantees that the model is original and compliant. This "grey card", which can be consulted online at any time, lists all the characteristics of the watch. Any intervention (maintenance service) approved by a watchmaker certified by the Watch House Certificate can be added to keep your timepiece's information up to date. This certificate indicates the current market value of your watch and can be used as an appraisal for approved value insurance. In practice, the Watch House Certificate comes in the form of a 28-gram brushed steel card, the size of a credit card, which respects the codes of luxury. Equipped with a QR code, it provides instant access to your timepiece's entire history.
