What Makes the Constellation Special
The Omega Constellation is one of the brand's most recognizable and enduring collections, defined by its famous "claws" (or griffes) that grasp the case and its integrated design. This specific reference, the 131.28.36.20.63.001, marries the classic Constellation architecture with the luxury of Omega's proprietary 18K Sedna™ gold, an alloy known for its exceptional luster retention. The brown sun-brushed dial and diamond-set bezel elevate the watch into the realm of high jewelry, offering significant wrist presence.
Technologically, the watch is powered by the Co-Axial Master Chronometer Calibre 8800. This in-house movement represents the pinnacle of Swiss watch precision, having passed rigorous testing by METAS (The Swiss Federal Institute of Metrology). The Master Chronometer certification guarantees superior accuracy (0/+5 seconds per day), performance, and resistance to magnetic fields up to 15,000 gauss. This 2025, unworn piece offers the buyer the latest model with cutting-edge movement technology and the full factory warranty.
