As a former partner with Tamaya in the development of its modern line of sextants, I take pride in offering an absolutely an absolutely outstanding example of Tamaya’s premier sextant,the Model 733 Spica which I helped design. It is Serial Number 42454, and comes with its original inspection certificate dated April 25th, 1981, and the original instruction booklet issued by the manufacturer. Its high impact plastic case is still being used with current production. All numbers match. The street price of this sextant new is over $1800.00

Many professional navigators judge this instrument to be the best of the modern sextants.

This instrument operates like a well oiled piece of machinery. It shows no minor evidence of wear. All the chrome parts glisten. The mirrors are spotless. The sextant’s paint is perfect, front and back. The only thing we did was replace the batteries.

As is, this sextant is exceptional and is ideally suited for a someone who seeks a high quality instrument. For use at sea, it should provide outstanding dependable service, and pride in the ownership of a premium Tamaya sextant which is considered by many to be the world’s best contemporary sextant.

QUALIFICATIONS: For purposes of judging whether my opinion counts, I was the editor of the chapter on sextants of the 1977 Edition of “Bowditch”, The American Practical Navigator, NAVPUB 9; a member of the U.S. Naval Academy Navigation Symposium Board, 1975-1978; the author of a book on marine sextants, Cornell Maritime Press,1975, and the founding president of Nautech Maritime Corporation which partnered with Tamaya of Japan in the introduction of the MS 733 Spica, the MS 833, Jupiter, MS 933 Venus sextants and the famous NC-2 navigation computer, in the U.S. market. I  am also a retired Master Mariner, and formerly held a U.S. Navy “D” Qualification as a Senior Skipper – Oceans.

It is deserving of someone who can appreciate the fine points of a sextant, and is willing to pay an appropriate price for this level of quality and excellence.
