The Omega Speedmaster Professional, affectionately known as the Moonwatch, holds a legendary status in the horological world. Its robust design, proven reliability, and historical significance – having been worn on the Moon – make it a highly sought-after timepiece. This article delves into the intricacies of the Omega Speedmaster Professional Calibre 1861, specifically addressing a common owner experience: slight timing irregularities immediately after winding. We will explore the reasons behind this phenomenon, compare it to other Speedmaster movements like the Calibre 3861, and examine the broader context of the watch within the market.
My recent experience with an Omega Speedmaster Professional Calibre 1861 (ref 311.30.42.30.01.005) revealed a minor quirk. After running it for a few weeks, I noticed some irregularities in its timekeeping, particularly noticeable in the hours immediately following winding. The watch would gain approximately 5-7 seconds over a few hours. This isn't a catastrophic malfunction, and it's important to preface this by stating that mechanical watches are inherently less precise than their quartz counterparts. However, understanding the source of this slight gain is crucial for appreciating the nuances of this iconic timepiece.
Before diving into the specifics of my experience, let's establish a broader understanding of the Omega Speedmaster Professional and its various movements. The Calibre 1861 is a manually wound, column-wheel chronograph movement. Its simplicity and robustness are key to its legendary status. It's a direct descendant of the Calibre 321, the movement used in the Speedmasters that accompanied the Apollo missions. While not as technically advanced as newer movements like the Calibre 3861, the 1861 retains a certain charm and mechanical purity. The Omega Speedmaster Moonwatch 1861, powered by this movement, remains a highly sought-after collector's item and a testament to Omega's commitment to its heritage.
The Omega Speedmaster professional watch price varies considerably depending on the model, condition, and retailer. Finding an Omega Speedmaster 311.30.42.30.01.005 on sale requires diligence and patience. Checking reputable online retailers and authorized dealers is crucial to secure a fair price. However, the price reflects the watch's prestige and historical significance. It's an investment piece, not simply a tool for telling time.
