The Omega Speedmaster family is vast and varied, encompassing a range of chronographs that share a common lineage but differ significantly in features, movements, and overall aesthetic. At the heart of this family lies the iconic Speedmaster Professional, often referred to simply as the "Moonwatch," a watch steeped in history and inextricably linked to NASA's Apollo missions. However, the term "Speedmaster" itself encompasses many other models, leading to frequent confusion about the distinctions. This article will delve into the key differences between the Omega Speedmaster Professional and other Speedmaster models, exploring various aspects to clarify the nuances within this prestigious collection.
Is Omega Making Speedmaster Pros?
Yes, Omega continues to produce the Speedmaster Professional Moonwatch. While the movement and some minor details have evolved over the decades, the core design and spirit of the original remain intact. The current production Speedmaster Professional uses the caliber 3861 movement, a co-axial escapement chronograph that offers improved accuracy and longevity compared to its predecessors. This ensures the continued availability of this legendary timepiece for future generations. However, it's crucial to understand that the modern Speedmaster Professional, while a direct descendant of the original, incorporates modern manufacturing techniques and materials, resulting in subtle differences compared to vintage models.
Omega Speedmaster Professional Movement: A Deep Dive
The heart of the Speedmaster Professional's legacy is its movement. Unlike many modern chronographs that utilize quartz or automatically winding movements, the Speedmaster Professional has historically relied on hand-wound mechanical movements. These movements, while requiring manual winding, offer a distinct charm and connection to the watch's heritage. The evolution of the Speedmaster Professional's movement is a fascinating story in itself:
* Caliber 321: This Lemania-based movement is considered by many collectors to be the most desirable. Used in early Speedmaster Professional models, including those worn on the moon, its intricate design and high-quality components are highly sought after. Omega has recently reintroduced a modernized version of the Caliber 321 in some limited edition models.
* Calibers 861/863: These movements succeeded the Caliber 321 and were also Lemania-based. They were simpler and more robust, making them suitable for mass production. They powered the Speedmaster Professional for many years, solidifying its reputation for reliability.
* Calibers 1861/1863: These movements represented a further simplification, sacrificing some of the aesthetic appeal of the earlier Lemania-based movements for increased efficiency and cost-effectiveness. They are still highly regarded for their accuracy and robustness.
* Caliber 3861: This is the current movement used in the modern Speedmaster Professional. It's a co-axial escapement movement, offering improved precision and longer service intervals compared to its predecessors. While it deviates from the Lemania lineage, it maintains the hand-wound functionality and overall aesthetic of the original.
The differences in these movements significantly impact the price and desirability of various Speedmaster Professional models. Vintage examples with the Caliber 321 command exceptionally high prices among collectors.
