Omega Speedmaster CK2915 Steel, black dial
Omega, 1957–1959
Why It Matters
The first Speedmaster. Introduced in 1957 as part of Omega's professional tool-watch trilogy, the CK2915 carried Broad Arrow hands, a natural-metal tachymeter bezel, and the column-wheel caliber 321. It set the template for every Speedmaster that followed, before the model gained its 'Professional' designation.
