The Omega Speedmaster Professional is arguably the most iconic chronograph ever made. Its association with NASA and the Apollo moon landings cemented its place in history, transforming it from a robust, everyday watch into a legend. While the hand-wound calibre 321 and its later iterations (like the 861) are often lauded, the automatic movement within the Speedmaster family, specifically the calibre 1151, deserves its own spotlight. This article delves into the Omega Speedmaster 1151, exploring its technical specifications, its place within the Speedmaster lineage, and its current market value, which can reach prices around $3,300.00 depending on condition and specific model.
The Omega Speedmaster 1151, often found in models like the Omega Speedmaster Date 3520.50 and various iterations of the Omega Speedmaster Mark 40 (sometimes referred to as omega mk40 Speedmaster), represents a significant step in the evolution of the Speedmaster line. Unlike its manually wound predecessors, the 1151 offered the convenience of automatic winding, a feature increasingly sought after by watch enthusiasts. This movement, however, is more than just a convenient upgrade; it showcases Omega's commitment to innovation and precision. Understanding the 1151 requires looking at its context within the broader Omega Speedmaster automatic mark and its relationship to other movements within the brand's extensive catalogue.
The Omega Speedmaster Automatic Mark: A Broad Canvas
The term "Omega Speedmaster Automatic Mark" is a broad classification encompassing several models featuring automatic movements. The 1151 is just one of the calibres used within this category, and its inclusion highlights the brand's strategy of offering a range of automatic Speedmasters to cater to diverse preferences. The automatic Speedmasters, unlike their hand-wound counterparts, often incorporated additional features like date displays, further enhancing their functionality and appeal. This diversification allowed Omega to maintain the Speedmaster's iconic design while expanding its market reach to those who preferred the ease of an automatic movement. The evolution of the automatic Speedmaster, therefore, is a story of continuous refinement and adaptation to changing consumer demands.
Omega Calibre 1151: A Closer Look at the Mechanics
The Omega calibre 1151 is a self-winding chronograph movement known for its reliability and robust construction. While not as historically significant as the calibre 321, the 1151 holds a special place in the hearts of many collectors due to its combination of practicality and performance. Its automatic winding mechanism ensures consistent power reserve, eliminating the need for manual winding. This feature, while seemingly simple, significantly enhances the user experience, making the watch more convenient for everyday wear.
