Omega Speedmaster Moonwatch Professional Watch - 42 mm Steel Case - Tachymeter Bezel - Black Dial - Black Leather Strap - 311.33.42.30.01.001

Powered by the legendary hand-wound Caliber 1863 movement, this 42mm stainless steel Speedmaster Professional carries the distinction of housing the same mechanical architecture that accompanied every crewed lunar mission. The black dial configuration paired with the robust steel case construction in reference 311.33.42.30.01.001 represents the purest expression of the Moonwatch lineage, maintaining the essential DNA established during NASA's rigorous testing protocols of the 1960s. This unworn example features the classic tachymeter bezel and black leather strap combination, preserving the tool watch aesthetic that made the Speedmaster an icon beyond its space exploration heritage.
