19th century
Description

You are viewing a collectable antique chronometer by J. Sewill of Liverpool

Circa 1880 on this amazing marine antique

The chronometer is housed in its original glazed three-tier mahogany case, complete with brass escutcheons, corner fittings and inset side handles which gives it a campaign look

The crisp silvered dial is beautifully engraved:

“Watchmaker to the Admiralty – J. Sewill, Liverpool & London”

Roman numerals for the hours

Outer minute track

Up-and-down power reserve indicator

Large subsidiary seconds dial

Blued steel hands and finely executed engraving consistent with mid- to late-Victorian manufacture

This Victorian marine chronometer dates from 1880 and sits inside a dark brown mahogany box. Brass-bound corners, inset brass side handles, brass hinges, and a central key escutcheon adorn the timber case, while the interior houses a silvered dial bearing Roman numerals, a power reserve indicator, a subsidiary seconds dial, and blued steel hands. A printed manufacturer trade label rests behind the glass inside the lid, alongside a white paper caution instruction note, a brass gimbal mount holding the instrument, and a separate brass winding key positioned in the corner. The whole piece measures 23 cm high, 23 cm wide, and 23 cm deep. In a contemporary home, this maritime instrument functions as a desk accessory in an office, study, or library. The compact proportions allow placement on a desktop, bookshelf, or display cabinet where the polished brass hardware and detailed dial work remain visible. Collectors of naval history or precision instruments integrate this box into traditional interiors as a functional decorative object.

A marine chronometer is a highly accurate portable timepiece used to determine longitude at sea by celestial navigation. First developed in the 18th century, these instruments solved the critical challenge of calculating a ships precise position during long ocean voyages.

Marine chronometers were housed in solid hardwood cases, often mahogany or rosewood, lined with brass fittings and brass-bound corners. The movement components utilised brass, steel, and jewelled bearings to withstand marine environments and thermal expansion.

Authentic pieces feature a brass brass-bound wooden transport box, a brass gimbal mount designed to keep the dial level despite ship movement, maker signatures on the dial or paper trade labels, and a dedicated winding mechanism.

A marine chronometer serves as a distinguished focal point when displayed on an executive office desk, bookshelf, or sideboard alongside historic maps, leather-bound books, and classic brass accessories.

Keep the chronometer away from direct sunlight, excess humidity, and direct heat sources to prevent the wood from warping. Dust the exterior gently with a soft cloth and consult a professional horologist for movement servicing.
