The Speedmaster is a classic in watchmaking. The Speedmaster Moonwatch Co-Axial borrows the classic appearance of the Speedmaster Professional but uses a larger case and an advanced automatic movement with co-axial escapement. This version (reference 311.63.44.51.04.002) features an orange-gold case, white dial and bezel, and a white alligator strap. As far as we know, this version never made it to production.
