This heritage watch features a 39.7mm stainless steel case with a domed sapphire crystal, vintage OMEGA logo, and Super-LumiNova-filled hands. Available in steel or leather strap versions, it blends timeless aesthetics with modern durability, powered by the manual-winding Calibre 3861. The watch commemorates OMEGA's space legacy with an engraved caseback, marking a historic moment in horological and aerospace history.
