The Growth of lysse Nardin

 Schnyder, Oechslin and the staff of Ulysse Nardin, design and create complication timepieces using modern materials and manufacturing techniques. The base movement used on all version of complication watches is the ETA. The new ETA 2892 movement, used by Ulysse Nardin in the New collection, is enormously popular because it is deemed accurate and reliable enough to be used as a base movement for many high-end manufacturers' complications. Most changes and updates were done in order to improve the efficiency of the automatic winding. The beat rate has been increased to 28,800 BPH, while the diameter of the movement was reduced from 28mm to 25.6mm to allow it to be used in a wider range of cases. (Hence, the change in model number from 2890 to 2892.) The thickness, however, remains unchanged at 3.6mm. This has the effect of reducing both the diameter and mass of the oscillating weight that was fixed in the 2892/A2 model. The 9mm diameter balance compromises between weight and size. The first example of Ulysse Nardin's new approach was the Astrolabium Galileo Galilei (1985, named after the device, Astrolabium, and the astronomer, Galileo). The Astrolabium displays local and solar time, the orbits and eclipses of the sun and the moon, and the positions of several major stars. It was named by the Guinness Book of Records in 1989 as the world's most functional watch (with 21 distinct functions). Oechslin followed the Astrolabium with two other astronomical watches, the Planetarium Copernicus (1988, named after the stargazing theaters called planetariums and the astronomer Copernicus) and the Tellurium Johannes Kepler (1992, named after element, tellurium, and astronomer, Johannes Kepler,). The three pieces constitute what the brand calls the Trilogy of Time. All 3 watches are with ETA bases.
