Omega Speedmaster: Also Called…
While officially named the Omega Speedmaster Professional, this iconic timepiece is often referred to by a variety of nicknames, reflecting its enduring legacy and powerful image:
* Moonwatch: This is undoubtedly the most common and widely recognized nickname, a direct reference to its role in the Apollo missions.
* Speedy: A shorter, more casual term used by enthusiasts and collectors.

Omega Speedmaster Models by Year: A Chronological Journey
The Omega Speedmaster’s history is rich and complex, with numerous variations and iterations produced over the decades. Tracking down precise specifications for each year and reference number can be a challenging task for even seasoned collectors. However, understanding the broad evolution helps in appreciating the nuances of different models. Key developments include:
* Early Speedmasters (1957-1960s): These early models laid the foundation for the iconic design. They featured different case sizes, movements, and dial variations, many of which are highly sought-after by collectors today. Significant changes during this period often involved movement upgrades and refinements to the chronograph function.
* The Calibre 321 Era (1957-1968): The legendary Calibre 321 movement, known for its elegance and precision, powered many of the Speedmasters worn during the Apollo missions. Watches featuring this movement are exceptionally valuable and collectible.
* The Calibre 861 Era (1968-1998): The Calibre 861, a more robust and cost-effective movement, replaced the Calibre 321. While not as prestigious as its predecessor, the Calibre 861 maintained the Speedmaster's reliable performance and is found in many historically significant examples.
* The Calibre 1861 Era (1998-Present): A modernized version of the Calibre 861, the Calibre 1861, continues to power many current production Omega Speedmaster Professionals. It maintains the manual-winding functionality while incorporating modern manufacturing techniques.
* Modern Variations (2000s-Present): Beyond the core Professional model, Omega has expanded the Speedmaster line significantly, offering variations with different materials, complications, and movements. These include the Speedmaster Reduced, the Speedmaster Date, and numerous limited-edition releases.
