This Omega Constellation breathes the style of the 70’s, with its tonneau shaped case with integrated bracelet. This Constellation model was the first Omega to have an integrated steel bracelet. The dial is silver with a very special finishing pattern. Omega thought that “Constellation” was such a strong brand that the Omega signature was repositioned to the 6 o’clock position. Inside the case beats the Omega 1001. Due to their totally new design (which was probably to ambitious in terms of frequency and thickness) these early 10XX calibers are notorious for problems when they are poorly maintained. However, this example was beautifully preserved and functions perfectly. A rare opportunity to buy a one of these Constellation without having to worry about the condition of the movement.

The bracelet is the original 1155/146, original to this watch and in very good condition. The case is absolutely unpolished, the racket might be re-brushed at one point  The bracelet is currently suitable for a 18-19cm wrist, with over 2 cm of extra links inside the clasp and one spare bracelet link.


The watch is in very good condition and fully original. The case is unpolished and therefore shows some signs of wear like little scratches. The crystal is original and signed with the Omega logo. The crown is original and signed with the Omega logo. The dial is in mint condition. The hands are original and in very good condition. The movement is in very good condition, operates smoothly and runs accurate within 20-30 seconds a day. The movement has been fully serviced and the watch comes with a 1 year warranty.

Omega Watch Co was founded in La Chaux de Fonds in 1948 by Louis Brandt, under the name La Generale watch Co. The company collected watch parts manufactured by craftsmen in the region and assembled then into complete watches. The company started to focus on industrializing the manufacturing of watches and making parts interchangeable. In 1894, the caliber 19 was launched. Soon after, this calibre was named Omega, the letter that stands for perfection in the Greek Alphabet. in 1903, the decision was made to sell al watches produced by the company under the name Omega. 

In 1903 Omega was employing well over 800 employees and producing over 240.000 watches a year, making it the biggest Swiss watch manufacturer of that era. Omega won numerous medals for precision timekeeping in chronometers trials. As a result from these achievements, Omega was appointed official timekeeper for the 1932 Olympics. In 1948 the Seamaster was introduced, followed by the Constellation in 1952, the Speedmaster in 1957 and the De Ville in 1960.
