Omega Constellation They have been around for more than 60 years, and their timeless design has made them a favorite among watch enthusiasts. There are several different versions of the Omega Constellation, but they all share some common design features. The most notable feature is the star-shaped logo on the dial, which has become a hallmark of this line of watches.

Omega Marine Unlike every other watch they produce, the Marine design features a rectangular casing rather than a circular one. This makes it very reminiscent of the Cartier Tank – one of the world's best-known dress watches (famously worn by Princess Diana). It's just a shame Omega doesn't produce them anymore!
