With over 20 years of experience in the international watch market, I have developed a comprehensive understanding of timepieces through auctions, fairs, and private transactions.

As a certified watchmaker (since 2024), I focus on the servicing, maintenance, and regulation of mechanical watches, combining technical precision with in-depth market knowledge.

In January 2026, I obtained a University Certificate in Judicial Expertise Law from Université libre de Bruxelles (ULB), strengthening my ability to operate in expert and legal contexts.

My work includes diagnostics, regulation, and maintenance, with a strong focus on performance, accuracy, and preservation. I also provide watch valuation, authenticity assessment, and condition analysis.

I offer private expertise services and contribute to judicial procedures, assisting collectors, professionals, and legal stakeholders.

I am committed to a discreet, rigorous, and detail-oriented approach, tailored to clients who value both craftsmanship and expertise.
