4.1307 Ulysse Nardin ‘Sideral Chronometer’ Pocket Watch No. 88111, Stainless Steel, Switzerland, 1950-1960

A recent creation by Ulysse Nardin – marine themed ‘Sideral’ pocket watch chronometer. Typical Ulysse Nardin movement with 17 ruby jewels. Beautiful original enamel dial with Arabic numeral and small seconds display – this is a rare, super high-quality collectible item. Not to be missed! Comes with a 6-month warranty.

A relatively modern Ulysse Nardin tool high precision pocket watch. The dial is classic enamel and very finely crafted, and the case is made of solid stainless steel, complete with hallmarks and serial numbers. The exact time of manufacture is difficult to determine, but presumably it would be in the 1950’s and 60’s. The serial number on the movement points to the 1910’s – 20’s, but the case, as well as the anchor design on the dial point to the post-war years. Small-scale production of warehouse mechanisms is most likely.

It is worth noting the integrity of the watch. Its preservation is exclusively collectible – the item is as good as new. The case is a shining, polished stainless steel, contrasting with the enamel of the dial, and the hands of an exquisite dark-eggplant shade of blue. The movement is well preserved, almost like a new watch – the polished body and glass shines and shimmers. It also runs like new; the inaccuracy is only off by a few seconds per day.

Key Information About ‘Sideral’ or Sidereal Charting

The name ‘Sideral’ indicates that the purpose of the watch is for counting sidereal time. Sidereal time is determined by the sea sextant according to the position of the stars in the sky, and then compared with the ship’s keeper of the accurate Greenwich time – the marine chronometer. Comparing the sidereal time and Greenwich Mean Time allows you to find the longitude with an accuracy that is quite sufficient for safe navigation on nautical charts.

About the Brand

Ulysse Nardin was founded in 1846 in the Swiss province of Le Locle, by the talented watchmaker Ulysses Nardin. Soon after the company started production, they began to concentrate on the creation of high-precision timekeeping devices, in particular marine chronometers, as well as complex watches containing minute repeaters, perpetual calendars, and chronographs. Keeping the jewellery and decorative component to a minimum, U. Nardin found that the formula for success in the art of precision mechanics was functionality, accuracy, and reliability.
