Crafted from luxurious 18K Moonshine™ Gold, the 39.4 mm case features elegant faceted \"dog-leg\" lugs and a refined bezel that reinterpret the iconic Constellation models of the 1950s. The matching yellow \"Pie-Pan\" dial, also made from 18K Moonshine™ Gold, showcases a crystal-finished center, opaline dodecagonal facets, and eight hand-guilloché grooves that create remarkable depth and brilliance. Diamond-polished dauphine hands and newly designed kite-shaped indexes, crafted from 18K Moonshine™ Gold, are complemented by the applied OMEGA logo and the signature Constellation star. A domed, bevelled sapphire crystal with anti-reflective treatment on both sides protects the dial while offering exceptional clarity. Visible through the sapphire exhibition caseback is the exceptional OMEGA Co-Axial Master Chronometer Calibre 8915, featuring an 18K Moonshine™ Gold rotor and balance bridge adorned with an applied Constellation Observatory medallion. Certified by METAS, the self-winding movement offers resistance to magnetic fields up to 15,000 gauss, a convenient time-zone function, and a 60-hour power reserve.
