Every single antique dealer on our platform is individually approved by our internal team. We verify their professional trade history, ethical standards, and photographic quality to ensure a secure, high-standard buying environment. Upon joining, every dealer agrees to a strict 9-point code of conduct. While issues can occasionally arise, our dealers typically resolve them swiftly and directly with the buyer. In fact, since our founding in 2002, Sellingantiques has only had to step in to help resolve an issue on roughly five occasions—a true testament to the quality of our dealers and their dedication to your happiness.
Our dealers are highly experienced in packing and shipping fragile, high-value antiques. Because you are in direct contact with the dealer, you will be able to easily go through all available shipping and insurance options together to ensure your item arrives safely.
Antiques are the ultimate green purchase. By choosing historical pieces over newly manufactured goods, you completely eliminate the carbon footprint of modern mass production while preserving exceptional, timeless craftsmanship.

An Edwardian arched mantel clock is a spring-driven wooden timepiece produced during the early 20th century, typically characterised by a rounded or domed case profile, inlaid marquetry, and compact proportions suitable for display on a shelf or mantelpiece.

These clocks were commonly constructed using a solid or veneered hardwood case, such as mahogany or oak, accented with boxwood stringing, brass bezel rims, glass dial covers, and precision brass mechanical clockworks.

Authentic period examples feature hand-assembled mechanical movements, genuine maker stamps or trademarks on the dial and movement plates, authentic period patina, and construction methods consistent with late 19th and early 20th-century horology.

Position the clock centrally on a fireplace mantel, sideboard, or study bookshelf to serve as a focal point, pairing it with neutral decor elements to highlight the rich timber tones and metal dial detail.

Keep the wooden case away from direct heat sources and sunlight to prevent timber shrinkage or veneer lifting. Dust the surface with a lint-free cloth and have the internal mechanical movement cleaned and lubricated by a professional horologist every five to seven years.
