The Omega Speedmaster Professional, affectionately known as the Moonwatch, holds a unique place in horological history. Loved on Earth and beyond, this iconic timepiece has witnessed pivotal moments in human exploration, solidifying its status as a legend. This comprehensive guide delves deep into the specifications of the Omega Speedmaster Professional, covering its various aspects, from its rich history and diverse models to its technical features and considerations for potential buyers.
Omega Speedmaster: Also Called
While officially the "Omega Speedmaster Professional," this watch is commonly referred to by several nicknames, each reflecting its enduring legacy:
* Moonwatch: This is perhaps the most popular moniker, earned after it became the first watch worn on the Moon during the Apollo 11 mission.
* Speedy: A shorter, more casual term of endearment used by enthusiasts and collectors.
* Calibre 321 (or 1861/1869): Often used to specify the movement inside, highlighting the historical significance of specific calibres.
Omega Speedmaster Models by Year:
The Omega Speedmaster's history is rich and complex, with numerous iterations and variations produced over the decades. Pinpointing every single model by year would be a monumental task, but we can highlight key eras and significant changes:
* Pre-Professional Era (1957-1968): This period saw the evolution of the Speedmaster from its initial release to the model that would ultimately go to the Moon. Key changes involved refinements to the case, dial, and movement, culminating in the CK2998 and the early reference 105.003 and 105.012 models that NASA selected for its space program. These early models are highly sought after by collectors.
* Professional Era (1968-Present): This era encompasses the models that have become synonymous with the Moonwatch. While the basic design has remained relatively consistent, there have been significant changes in movements, materials, and minor aesthetic details throughout the years. Key reference numbers include the 145.012, 145.022, and the modern 311.30.42.30.01.005 (and many variations within each reference). These differences often reflect changes in production methods, material availability, and movement technology.
* Modern Variations: Omega has also released numerous limited editions and variations on the Speedmaster Professional design, often incorporating different materials (like platinum or ceramic), dials, and straps. These variations maintain the core design DNA but offer unique aesthetic options for collectors. These are typically marked by specific reference numbers and often have higher price points.
Understanding the specific reference number is crucial when identifying a particular Omega Speedmaster model and its age. These numbers, often found engraved on the caseback, offer a wealth of information about the watch's history and specifications.
Omega Speedmaster Sizes:
The Omega Speedmaster Professional has primarily remained consistent in size throughout its history, though there have been subtle variations:
* Traditional Size (around 42mm): This is the standard size for the majority of Speedmaster Professional models. This size provides a classic, balanced look on most wrists.
* Variations: Some limited editions or specific models might have slightly larger or smaller cases, but the 42mm diameter remains the benchmark. Omega has also released variations with different lug-to-lug measurements, which can affect how the watch wears on the wrist.
