The Speedmaster Moonwatch stands as a symbol of Omega's pioneering spirit, having accompanied astronauts on all six moon landings. This 42 mm edition, inspired by the 4th generation Speedmaster, boasts a case and bracelet crafted from 18K Moonshine™ Gold, a unique alloy developed by Omega in 2019. Its distinct paler hue and high resistance to fading over time set it apart from traditional 18K yellow gold. The watch features a sun-brushed 18K Moonshine™ Gold "step" dial with blackened subdials and indexes, complemented by a black ceramic bezel ring featuring OMEGA Ceragold™ tachymeter scale, including the famous dot over 90.

The caseback, also in polished 18K Moonshine™ Gold, bears double bevels and is engraved with the iconic words "FIRST WATCH WORN ON THE MOON" in black. Powering this timepiece is Omega's Co-Axial Master Chronometer Calibre 3861 with a special luxury finish. It incorporates cutting-edge components, from the Co-Axial escapement for enduring precision to the silicon balance spring for remarkable anti-magnetic properties.

Omega's expertise in ceramics, spanning over a decade, is evident in the watch's construction. Ceramic, derived from the Greek word "keramos," is an inorganic, non-metallic substance fired at high temperatures, resulting in exceptionally durable and mechanically robust components. Notably, ceramic is twice as light as stainless steel, highly scratch-resistant, and possesses hypoallergenic and non-magnetic properties. The watch also features synthetic sapphire crystal with an anti-reflective treatment, ensuring exceptional clarity and scratch resistance. Graded 9 on the Mohs hardness scale, the sapphire crystal is nearly impervious to scratches, guaranteeing a clear view of the intricate details of the timepiece. This manual-winding chronograph movement with Co-Axial escapement is certified as a Master Chronometer by METAS and is resistant to magnetic fields up to 15,000 gauss. Its free-sprung balance with silicon balance spring, rhodium-plated finish, and bridges with straight Geneva waves further exemplify Omega's commitment to precision engineering.
