In 1952, Omega launched the Constellation collection with the aim of offering high-quality, precision-built watches.
In addition to the Constellation inscription and the star applied to the dial, on the case back you can see the image of the Geneva Observatory with eight stars, representing the eight chronometry competitions won by Omega to date.
Therefore, all models in the Constellation collection are equipped with COSC (Contrôle Officiel Suisse des Chronomètres) calibres, proudly displaying this certification on the dial (Chronometer Officially Certified).
In 1964, the C-Shape line appeared, in reference to the design of this case, whose creator was the illustrious Swiss watchmaker and artist Gérald Genta, resulting in a revolution in terms of design, with a cleaner dial, thinner baton-type hands and subtle markers, giving more presence on the wrist.
The nickname “C-Shape” comes from the shape of the case, in allusion to two letters C’s opposite each other, with rumors that Genta was inspired by the letter C because it is the initial letter of the Constellation collection, in addition to being the third letter of the alphabet, a relation to the third era of the Constellation line.
