This Edwardian mantel clock originates from the First World War period, dating to circa 1918. The piece takes the form of an arched dome top mantel clock constructed from mahogany with a warm brown timber colour, complemented by delicate marquetry inlay decoration, a circular brass-rimmed glass-covered dial with Roman numerals, and small turned brass feet elevating the base. A silver-plated presentation plaque is mounted centrally on the front plinth below the dial. The physical dimensions measure 30.5 cm high, 36.2 cm wide, and 13 cm deep. In a modern interior, this clock suits placement upon a living room mantelpiece, a study bookcase, or a gentleman's library desk. The design integrates easily into traditional or period-inspired interior schemes, bringing functional timekeeping and historical character to a shelf, sideboard, or mantel.

FAQs

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.
