Our complete mastery of servicing techniques, complex repairs, manufacturing of vintage movement components, and fine horological restoration ensures that your timepiece retains its full authenticity and original condition.
Every intervention is performed according to the highest standards of traditional watchmaking craftsmanship.

Thanks to our expert watchmakers and specialised technicians, Alliance Genève is the only Geneva-based workshop capable of operating with such precision, efficiency, and discretion.

Our workshops house an extensive inventory of vintage and contemporary horological components, enabling us to perform servicing, repairs, and restorations across the major Swiss watch brands.

Recognised in Geneva and internationally for our expertise, discretion, and uncompromising quality standards, we collaborate with leading jewellers, watchmakers, and precision machinists to provide restoration services rooted in the most prestigious Geneva watchmaking traditions.

Our clients — including watch manufactures, jewellery houses, dealers, auction houses, and collectors — entrust us with their exclusive, rare, and valuable timepieces for exceptional restoration and maintenance services.

Our services also include a warranty and archival system providing a comprehensive document detailing all essential information relating to your watch: serial number, model reference, work performed, and, most importantly, a fully referenced high-definition image enabling precise identification of the timepiece — the equivalent of a true horological DNA profile.

Look no further, you are dealing with genuine on-site experts.

Thanks to our recognised expertise and modern infrastructure, Alliance Genève is regularly commissioned by auction houses, dealers, and collectors to conduct technical assessments, identifications, and valuations of antique, vintage, and contemporary watches.

Using our proprietary high-precision technology, we identify and scan the smallest details of your watch — micro-scratches, galvanised surfaces, ink markings, and other unique characteristics — at a level of definition exclusively offered by Alliance Genève.

Our pioneering 2D and 3D digital scanning technology allows us to create a unique horological DNA document for each timepiece.

This horological DNA profile guarantees that your watch can always be accurately identified, protecting you against fraud and against any damage or alteration caused by third parties.

The data relating to each of your collectible timepieces is securely stored within our own protected digital infrastructure hosted in Switzerland.

Your information is additionally registered on a Blockchain network to guarantee the integrity and immutability of the recorded provenance data.

Through your secure digital access, you may consult your collection at any time via smartphone, tablet, or computer, and fully appreciate the unique character and excellence of your timepieces.
