The Omega Speedmaster Professional. The name conjures images of lunar landings, daring astronauts, and unwavering reliability. But beyond the iconic case and instantly recognizable design lies a complex and fascinating mechanism: the movement. This article will delve into the heart of the Speedmaster Professional, exploring its evolution, variations, and the intricacies that make it a benchmark in horological history. We'll cover everything from identifying the best Omega Speedmaster movements to understanding model numbers, dial variations, and even charting the price history of this legendary timepiece.
Best Omega Speedmaster Movement: A Matter of Perspective
Defining the "best" Omega Speedmaster movement is subjective and depends on individual priorities. However, certain movements stand out due to their historical significance, technological advancements, and overall performance. The story begins with the calibre 321, the original movement powering the Speedmaster worn on the moon. Its manually wound, column-wheel chronograph mechanism represents a pinnacle of traditional watchmaking. While no longer in production for the Speedmaster Professional, its legacy remains powerful, and its resurgence in recent years (with the 321 re-issue) has cemented its place as a highly sought-after movement.
The calibre 861, the successor to the 321, took over production for many years. While lacking the aesthetic elegance of the 321's architecture, the 861 proved incredibly robust and reliable, further solidifying the Speedmaster's reputation for durability. It was the workhorse movement for countless Speedmaster Professionals, making it a significant part of the watch's history.
The current generation of Speedmaster Professional movements, primarily the calibre 1861 (manual wind) and the calibre 3861 (co-axial escapement, manual wind), represent a fascinating blend of tradition and innovation. The 1861 continues the legacy of the 861, offering a faithful, robust, and relatively simple mechanism. The 3861, however, marks a significant leap forward. Incorporating Omega's Co-Axial escapement, this movement boasts improved accuracy and longer service intervals, while maintaining the manual-wind functionality cherished by many Speedmaster enthusiasts. The Co-Axial escapement reduces friction, leading to greater precision and longevity, making the 3861 arguably the "best" in terms of modern performance. Yet, the historical significance of the 321 and the simple robustness of the 861/1861 should not be overlooked.
Omega Speedmaster How to Use: A Simple Guide
Operating a manual-wind Speedmaster is a straightforward process, though understanding the nuances enhances the experience. The crown has three positions:
1. Screw-down position (fully tightened): This protects the movement from water and dust. It's crucial to ensure the crown is fully screwed down before any water exposure.
2. First position (unscrewed, but not pulled out): This position is typically used to wind the watch. Turn the crown clockwise until you feel resistance. Over-winding is generally not a concern with modern movements.
3. Second position (pulled out one click): This position allows you to set the time. Turn the crown clockwise or counter-clockwise to adjust the hour and minute hands.
4. Third position (pulled out two clicks - for chronograph models): This position activates the chronograph functions. Pressing the top pusher starts the chronograph second hand. Pressing the bottom pusher resets the chronograph hands to zero. The sub-dials track elapsed seconds, minutes, and sometimes hours.
