Omega Constellation OMEGA Co-Axial Master Chronometer - 39 mm Steel And Sedna Gold Case - Brown Dial - 131.20.39.20.13.001

Powered by Omega's Master Chronometer caliber 8900, this 39mm Constellation demonstrates the Swiss manufacturer's commitment to anti-magnetic resistance up to 15,000 gauss while maintaining COSC chronometer precision. The brushed brown dial creates compelling visual depth against the stainless steel case construction, enhanced by Sedna gold accents that distinguish this particular reference 131.20.39.20.13.001 from standard steel variants. Constellation's signature "claws" secure a scratch-resistant sapphire crystal, while the Co-Axial escapement reduces friction and extends service intervals. This unworn example showcases Omega's modern interpretation of their 1952 astronomical observatory design language.
