The Omega Speedmaster Professional, a watch synonymous with lunar exploration and enduring style, boasts a rich history filled with variations and subtle differences across its numerous references. While the iconic 321 and later 861 movements capture much of the public's attention, the Omega Speedmaster 3511 (often seen with the additional ".50" designation, indicating variations in case or bracelet) represents a significant chapter in the Speedmaster saga, bridging the gap between generations and offering a compelling blend of vintage aesthetics and robust functionality. This article delves into the world of the Omega Speedmaster 3511, exploring its history, variations, key features, and providing guidance for prospective buyers navigating the market.
The 3511: A Transitionary Movement
The Omega Speedmaster 3511, launched in the late 1970s and continuing into the 1980s, marked a significant transitional period in Speedmaster production. It followed the legendary 861 movement, which itself was a descendant of the manually wound caliber 321, famously worn on the moon. The 3511, however, introduced a key difference: it was a more modern, automatic chronograph movement, a departure from the manually wound predecessors. This shift reflected Omega's adaptation to evolving market demands for greater convenience and functionality. While the 3511 might not carry the same immediate historical weight as the 321 or 861, its place in the lineage is crucial, representing a significant step in the evolution of the Speedmaster. The transition to an automatic movement didn't compromise the watch's ruggedness and reliability, making it a highly sought-after piece among collectors and enthusiasts.
Comparing the 3511 to its Siblings: 3513 and Beyond
Understanding the Omega Speedmaster 3511 requires a comparison with its close relatives, particularly the Omega Speedmaster 3513.50 and the Omega Speedmaster 3513.30.00. While all three share the Speedmaster Professional lineage and a similar aesthetic, they differ in key aspects:
