Dubbed "The World's Most Accurate Wristwatch", you are looking at a very rare piece of History!

Omega,“Constellation, Marine Chronometer, Megaquartz, f2,4 MHz”, No. 37057295, Ref. ST 198.0074 / 398.0836. Sold on May 3, 1976. Very fine, rare, and exceptionally accurate, large, rectangular, dead center seconds, water-resistant (but I cannot guarantee water resistance for a vintage like this), stainless steel gentleman`s wristwatch with date, independent hour adjustment and 14K gold bezel and an integral Omega bracelet with deployant clasp.

Comes with ORIGINAL chronometer certificate from the University of Besancon. Rare indeed! Compare with the one sold at Omegamania on 15 April 2007, No. 37057175 (as opposed to my 37057295), which was sold for CHF 7670! (about USD6,900!!!). I am offering this at US$3,800 plus shipping.
