The watches, measuring 41 millimetres in diameter, jealously guard the distinctive Constellation features, such as the iconic claws and half-moon facets at both ends of the case. In addition, Omega has integrated some of its finest and most advanced materials into the design, including models in stainless steel, 18-carat gold or a combination of both. In addition, all bezels are made of polished ceramic, to have the same look as the original 1982 Constellation, which featured a polished sapphire crystal. Only one model in the new collection features a stainless steel bezel, embellished with blackened Roman numerals. For all models with a ceramic bezel, the Roman numerals have been created in Ceragold or Liquidmetal. Bevelled along the edges of the case and on the claws, the collection has a slimmer appearance than past models, and the crown is also slightly reshaped. Following this style, the hands have also become slimmer and the new hour markers take inspiration from the Manhattan skyline, more specifically the triangular facets of the Freedom Tower. Many of the 2020 models will be presented with a leather strap and antibacterial rubber lining; a metal mesh then matches the edge of the strap to the case. Those who prefer a metallic look can replace the strap with the bracelet from the Constellation 39 mm collection, or with a leather strap. The sapphire glass back offers a view of the Omega Master Co-Axial calibre 8900/8901. All watches are Master Chronometer-certified by the Swiss Federal Institute of Metrology (Metas).
