Antique Sextants

Vintage and antique aviation and marine sextants and modern reproductions at competitive prices, with a new selection daily.

Here you can find maritime antique sextants from C. Plath, Cassens & Plath, H. Duren, H. Hughes, Heath and Co. Hezzanith Three Ring sextants, Lilley & Son and other vintage sextants. There is nothing like the fine brass and silver of a quality sextant, and because these fine instruments are treated with the greatest care possible aboard ship, collectors can find antique sextants in original boxes still in excellent condition after 100 years or more in the harsh marine environment aboard whaling ships, cargo vessels, and exploration mission ships. Collectors can also find good deals on WWII era US Maritime Commission Stadimeter Sextants from Leupold and Stevens, Schick, and others, along with military aviators' bubble sextants.

For those practicing the ancient art of determining position by using a sextant to measure the angle from the sun or stars to the horizon, there are also modern instruments available such as the Celestaire Astra IIIB Marine Sextant, Davis Mark 25 plastic sextant, and sextants from Freiberger and others. Those who just want a nautical decoration with historic accuracy but not navigational calibration can find quality reproduction brass sextants from Ross London and others.
