TAMAYA MS 833 JUPITER SEXTANT,
NEW CONDITION

PRICE $
800.00 PLUS $25.00 SHIPPING AND HANDLING TO 48 contiguous STATES.
 

We’ve been involved selling Tamaya sextants for over 30 years,
and back then, our company Nautech Maritime Corporation was instrumental in the design and introduction of their
MS 733 SPICA, MS 833 Jupiter, and MS 933 Venus sextants and the famous NC 2, and NC 77 navigation computers.

Therefore, it brings us pleasure to present a used 1978 Tamaya
Jupiter sextant, Serial Number 60659, with a 4 x 40 scope which is in exceptional condition, and
shows little evidence of use.  The case is a dark rose colored wood which is typical of
those of that era.

CONDITION: Irrespective
of age, overall condition, is “as near new”. Adjustable index and side error are nil. All moving parts
turn freely. Nothing is broken. The illumination works. The only exception is a small scratch on the handle.
Mirrors are perpendicular to frame. Both mirrors are without blemish. The case is in excellent condition. The
sextant’s paint is as new. All the numbers match. There is no reason to grade this sextan anything but exceptional.

STAR RATING: Without qualification, this
instrument rates 5 STARS

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.
