By Barnett is a luxury watch dealer and custom fine jeweler based in Beverly Hills, founded in 2019 by Erin Barnett, a GIA-certified jeweler.
The business was built on one idea: bring transparency to an industry where buyers are too often unsure what they are paying for. Every watch is examined and verified before it is offered, and every custom piece is made to the client's brief.
What we do
- Luxury watches. We buy and sell pre-owned luxury watches from brands including Rolex, Patek Philippe, Audemars Piguet, Cartier, Omega and Richard Mille. Browse all watches.
- Watch sourcing. Looking for a specific reference? We search our network of trusted industry contacts, often within 24 hours. Learn about sourcing.
- Selling and consignment. Sell your watch or consign it and receive up to 91% of the sale price. Sell or consign.
- Custom fine jewelry. Pieces designed with you, from concept to finish. Jewelry purchased from By Barnett includes free cleanings for life (watches not included). Create your own.
Authenticity first
Every watch goes through authentication and inspection: we verify authenticity, reference and specifications, and examine condition and components. Read about our process.
