The Omega Moonwatch Professional Co-Axial Master Chronometer Chronograph (Ref. 310.30.42.50.01.002) stands as a modern evolution of one of the most iconic timepieces in horological history—the legendary Speedmaster worn during NASA’s Apollo missions. Its 42 mm stainless steel case maintains the timeless asymmetrical design, complemented by a deep black dial with stepped subdials and a matching black bezel featuring a tachymeter scale. The polished and brushed steel bracelet adds to its robust yet refined appeal, while the hesalite crystal preserves its vintage character.

Certified by METAS, it guarantees remarkable accuracy and reliability under the most demanding conditions. Water resistant up to 50 meters, this chronograph bridges the past and present—honoring its lunar legacy while incorporating the latest in Omega innovation. The Moonwatch Professional remains a symbol of human achievement and exploration, a watch that continues to inspire with every second it measures.
