Constellation, that's the name of the Omega watch that was the first to be tested for accuracy by the observatory. That's why the center of the back case is engraved with the observatory logo with eight stars, which mean the eight criteria for testing these watches. The Globemaster model series first saw the light of day in 1952. In an elegant model with a plastic convex dial, simple indexes and hands. Globemasters were introduced in 2015 as the first master chronometers, which again means very strict accuracy certification and antimagnetic properties.
