The Omega Speedmaster Professional Moonwatch, specifically the model with the legendary caliber 1861 movement, holds a unique place in horological history. More than just a watch, it's an icon, a testament to human ingenuity and a symbol of exploration. This article will delve deep into the intricacies of the Speedmaster Professional Moonwatch Cal. 1861, exploring its history, accuracy, movement characteristics, and comparing it to other movements within the Speedmaster family, including the caliber 1863. We'll also touch upon the special edition celebrating the Tokyo Olympics (522.20.42.30.06.001) and discuss the current market price of these coveted timepieces.
A Legacy Forged in Space:
The Omega Speedmaster's journey to becoming the "Moonwatch" is a captivating story. Its selection by NASA in 1965, after rigorous testing, cemented its place in history. The Speedmaster Professional, specifically those equipped with the caliber 321 and later the caliber 861 (and its near-identical successor, the 1861), accompanied astronauts on all six Apollo lunar missions. This enduring association with space exploration is the foundation of its enduring popularity and legendary status. The caliber 1861, a manual-winding movement, is a direct descendant of the caliber 861, and is highly sought after by collectors for its robust construction and direct lineage to the watches worn on the Moon.
Omega Speedmaster 1861 Accuracy and Movement Rate:
The caliber 1861 is renowned for its reliability and robustness, not necessarily for its pinpoint accuracy compared to modern chronometers. While it's not designed for the extreme accuracy of a COSC-certified chronometer, its performance is consistently dependable within acceptable parameters for a manual-winding chronograph. The movement rate typically falls within a range considered acceptable for its era and intended purpose. It's crucial to understand that the focus of the 1861 wasn't on achieving the highest possible precision in terms of seconds per day, but rather on its resilience and ability to withstand the harsh conditions of space travel. Regular servicing by a qualified watchmaker is essential to maintain optimal performance and accuracy. The variations in rate are often attributable to factors like temperature fluctuations, the mainspring's power reserve, and the wearer's activity level. While not as precise as some modern movements, the 1861's reliability under duress is unmatched.
Omega Speedmaster 1863 Movements:
The Omega Speedmaster Professional caliber 1863 represents a shift in production methods. While functionally similar to the 1861, the 1863 incorporates some cost-saving measures in its manufacturing process. This often translates to slightly less hand-finishing and potentially a minor difference in overall perceived quality, though the fundamental reliability remains. The key difference lies in the manufacturing techniques used. The 1861 benefits from a more traditional approach to finishing, resulting in a higher level of craftsmanship that appeals to many collectors. The 1863, while still a high-quality movement, showcases a more streamlined and efficient manufacturing process. This makes the 1863 a more readily available and often more affordable option.
