Record status
Individual type · partial
Period
circa 1920
This two-day marine chronometer by Dobbie McInnes & Clyde Ltd. features a sophisticated 11-jewel fusee movement, incorporating Harrison's maintaining power and an Earnshaw's escapement.
Designed for maritime precision, it is free sprung and utilizes a cut bimetallic balance with a diamond end stone and a helical balance spring. The movement, identified by serial number 13348, is housed within a gimbaled, lacquered brass bowl that rests in a three-tier mahogany box fitted with brass furniture. The silvered dial features black Roman numerals, a dedicated wind indicator, and blued steel spade and poker hands.
Included with the chronometer are a box key, a winding key, and the fusee chain. The overall assembly measures 8 inches by 7.25 inches by 7.25 inches. Reflecting its intended use as a nautical instrument, the mahogany case and brass housing demonstrate a robust construction, with the movement being both clean and functional. The chronometer represents the high standard of precision timekeeping instruments required for celestial navigation during the early 20th century.
