Today's offering showcases this striking mens automatic Ulysse Nardin. It has a strong retro style case and royal blue dial.

Measuring 34mm in diameter by 40mm long, it is the size of a Rolex Date model. And like a Rolex, it is powered by an automatic movement that has been officially certified as chronometer, the highest distinction given to a watch movement.

Besides being a certified chronometer, it also features a high frequency 36,000 beats per hour balance system, twice the speed of many traditional watches and the fastest beat rate of the era, insuring exceptional accuracy.

Only a few specialist models of watches from a handful of brands beat at 36,000 per hour. As both a high frequency watch and a officially certified chronometer, this watch would have been among the very best when it came to accuracy in a widely-produced watch at the time.

It presents in gorgeous condition. It has just finished a true expertly done restoration and presents as about a 9.8 out of 10. The dial has been meticulously refinished - the printing could pass as UN factory done to the naked eye. As part of the restoration, the movement has been freshly overhauled by a Master Watchmaker.

Included with the purchase is a one-year C.O.T. warranty on the movement and its function, a custom printed Connoisseur of Time Certificate of Authenticity, and a new timing certificate.

An over four decade old classic Ulysse Nardin chronometer that presents like new on the wrist!

Ulysse Nardin:
Ulysse Nardin is best known by many collectors for creating chronometers, extremely accurate time keeping instruments. Their marine chronometer used by ship's captains to plot and follow the correct course while at sea. By employing sextants and chronometers, a captain could track the changes in his course over time and determine the exact location of his ship, and Nardin's marine chronometers were among the most reliable and sought after.
