Crafted from luxurious 18K Sedna™ Gold, the 39.4 mm case showcases the collection's distinctive faceted \"dog-leg\" lugs and sharply defined bezel, paying tribute to the legendary Constellation models of the 1950s. The elegant pink \"Pie-Pan\" dial, also fashioned from 18K Sedna™ Gold, features a sun-brushed center, opaline dodecagonal facets, and eight hand-guilloché grooves that create exceptional depth and light reflection. Diamond-polished dauphine hands and redesigned kite-shaped indexes in 18K Sedna™ Gold are complemented by the applied OMEGA logo and iconic Constellation star. A domed, bevelled sapphire crystal with anti-reflective treatment on both sides ensures outstanding legibility, while the sapphire exhibition caseback reveals the exceptional OMEGA Co-Axial Master Chronometer Calibre 8915. Certified by METAS, this self-winding movement is the world's first two-hand calibre to achieve Master Chronometer certification, offering resistance to magnetic fields up to 15,000 gauss, a practical time-zone function, and a 60-hour power reserve. The movement is further enhanced by an 18K Sedna™ Gold skeletonized rotor and balance bridge, beautifully decorated with an applied Constellation Observatory medallion.
