Watchfinder & Co. opened its Mayfair boutique on Avery Row in 2017. Clients can buy, sell and part-exchange luxury pre-owned watches from brands including Rolex, Omega, Cartier & Patek Philippe, and can arrange to view any of their 5000+ timepieces at the boutique. Every watch is covered by Watchfinder's 24-month warranty, with each piece authenticated, inspected, and restored at their manufacturer-certified service centre.
