Certificate of authenticity and warranty card


5 years

Our priority is to guarantee the proper functioning of the pieces that leave our workshops. Due to our interventions on your timepiece, the manufacturer automatically cancels its original warranty. We replace it with our own 5 year international warranty. To be able to address every need, we offer a worldwide after-sale service. Each timepiece that we modify is provided with its own certificate of authenticity, individually numbered, dated and signed, providing a full traceability.
