Pre-owned Omega Speedmaster ref 310.20.42.50.99.001 (2025) takes the familiar Moonwatch design and gives it a more elevated aesthetic. The core layout is unchanged. 42mm case, asymmetrical profile, and the classic chronograph setup that traces back to the watches worn during the Apollo missions. What sets this model apart is the use of Sedna gold alongside stainless steel. The bi-color case and bracelet add warmth, while the black ceramic bezel with a Ceragold tachymeter scale is very grounded. The dial has a sun-brushed Sedna gold finish and contrasting black sub-dials that bring a bit more depth to the watch. It feels like a more refined take on the standard Moonwatch without losing the original identity. Shop OMEGA Speedmaster Collection
