The Constellation collection, founded in 1948, is a collection of watches that began with the Centenary, a watch designed by René Banwart. The watch was made in limited numbers, with 6,000 made in 1952. The Constellation was named after the emblem on the caseback, which showed an observatory with eight stars above it. The watch was known for its distinctive faceted convex dial, known as a "pie-pan dial." The collection evolved over the 1960s, with models featuring simpler dial designs and a wider variety of case shapes.
The Constellation also pioneered quartz watch technology, with the first commercially available quartz watch, the Astron, released in 1969. Today the line is still just as diverse, with mechanical chronometers and Master Chronometers. The collection includes a wide range of case materials and combinations, representing the latest chapter in the history of one of the longest-lived and most important wristwatch collections in the history of wristwatches.
