The Speedmaster is a timeless classic in watchmaking. The Speedmaster Moonwatch Co-Axial mirrors the classic look of the Speedmaster Professional but comes with a larger case and advanced automatic movement with co-axial escapement. This version (reference 311.33.44.51.04.001) features a stainless steel case, a white dial and bezel, and a white alligator strap. As far as we know, this version was never put into production.
