"Ω" is the 24th and last letter of Greek. It symbolizes the beginning and end of things, the first and the last, similar to the cycle of "the last means the beginning, and the end is also the beginning" in Asian philosophy. It represents the extraordinary quality of "perfection, extreme, excellence and achievement" and interprets Omega's business philosophy of pursuing "excellent quality" and its spiritual style of "advocating tradition and being brave in innovation".

Omega’s “Speedmaster Professional” timer was the first watch used on the moon. All subsequent NASA space missions involving humans used this brand of watches. Omega's "Seamaster 300m Waterproof Swiss Observatory Certified Chronometer" (Seamaster 300m Diver Chronometer) has become James Bond's designated watch. It has been with Bond since it first appeared in the 007 movie series "GoldenEye". A close-up shot of the Omega Seamaster 600-meter professional waterproof watch (Seamaster Professional 600) also appeared in Luc Besson's movie "The Big Blue". This watch is also one of the watches produced by Omega that is very suitable for collection. Since the 1932 Summer Olympics, Omega has often become the official timekeeper of the Olympic Games. This practice continued at the 2006 Winter Olympics and the 2008 Summer Olympics.
