FAQs

A sextant is a doubly reflecting navigational instrument designed to measure the angle between the horizon and a celestial body. Developed in the eighteenth century, it was a fundamental tool for mariners to calculate latitude and longitude at sea.

Antique sextants are primarily constructed from cast brass or bronze frames to withstand maritime environments, featuring inset silvered scales for precise calibration, glass optical lenses, shade filters, and turned wooden handles.

Authentic sextants feature hand-engraved scale markings often laid onto inset silver strips, alongside serial numbers or maker marks near the arc. They display fully articulated mechanical parts, including index arms, fine-adjustment screws, and hinged filter shades.

An antique brass sextant functions as a technical accent on an office desk, styled within a gentlemans library bookcase, or displayed beneath a glass dome on a sideboard.

Dust the instrument gently using a soft, dry microfibre cloth or horsehair brush. Avoid chemical metal polishes that strip protective lacquers or obscure fine scale engravings, and keep optical glass clean with specialised optical wipes.
