Vintage Carved Mother of Pearl Flower Brooch Watch

This is a vintage ladies' lapel or brooch watch featuring a prominent floral motif. The centerpiece is a five-petal flower intricately carved from mother-of-pearl, displaying a soft iridescence with pink and green luster. The petals are secured by gold-tone metal prongs. Suspended by a small circular link from the flower is a round, gold-tone mechanical watch head. The watch face is white with gold-tone Arabic numerals and hands. The brand marking on the dial appears to be 'Sheffield' or a similar mid-century maker. The construction indicates a style prevalent in the 1940s to 1960s. Regarding condition, there is visible oxidation and patina on the metallic components, particularly the prongs and the watch case. The movement is reported as non-functional, which is common for mechanical watches of this age (~60+ years) that have not been serviced. There are no missing petals, though there is minor surface wear on the metal finish. The item is presented in a modern 'Jared The Galleria Of Jewelry' box, which is not original to the piece's era.
