The Omega Speedmaster Professional Moonwatch, a legend in horology, enjoys a unique position in the watch world. Its iconic status, cemented by its role in the Apollo 11 mission, ensures continuous fascination and demand. However, even within this iconic lineage, subtle changes occur, leaving collectors and prospective buyers wondering about the differences between specific years. This article delves into a detailed comparison between the Omega Speedmaster Professional Moonwatch of 2020 and its successor from 2021, examining the nuances that distinguish these seemingly similar timepieces. We’ll also explore related topics like the limited-edition Tokyo 2020 models, pricing, water resistance, and ultimately, which Speedmaster is right for you.
The Genesis of the Change: Subtle Shifts in a Legendary Design
The 2020 and 2021 Speedmaster Professional Moonwatches appear almost identical at first glance. Both boast the classic 42mm stainless steel case, the iconic tachymeter bezel, the Hesalite crystal, and the unmistakable three-subdial layout. However, a closer inspection reveals key differences, largely centered around the movement and subtle adjustments to the dial and hands. These changes, though seemingly minor, can significantly influence a collector's decision.
Movement: The Heart of the Matter
The most significant difference lies within the movement. The 2020 models primarily housed the calibre 1861, a manual-winding movement that reflects the historical accuracy of the original Moonwatch. This movement, known for its robustness and simplicity, is a testament to Omega's commitment to heritage. The 2021 models, however, saw a shift to the calibre 3861, a master chronometer-certified movement. This seemingly small change represents a significant leap in performance and reliability.
The calibre 3861 offers several advantages:
* Master Chronometer Certification: This prestigious certification, awarded by METAS (the Swiss Federal Institute of Metrology), guarantees superior performance in terms of accuracy, magnetic resistance (up to 15,000 gauss), and power reserve (approximately 50 hours). The calibre 1861 lacks this certification.
* Improved Precision: The calibre 3861 exhibits enhanced accuracy compared to its predecessor. This is a crucial factor for those seeking a more precise timekeeping instrument.
* Co-Axial Escapement: The integration of the co-axial escapement significantly improves the long-term performance and reduces the need for frequent servicing.
While the calibre 1861 has a certain charm due to its historical significance and minimalist design, the calibre 3861 offers demonstrably superior performance and longevity, making it a more compelling choice for many modern buyers.
Dial and Hands: A Matter of Detail
Beyond the movement, subtle differences exist in the dial and hands. While the overall design remains consistent with the historical aesthetic, some minor variations can be observed. The application of lume (luminescent material) might be slightly different, and the shade of the dial itself could vary subtly between batches and years. These variations are usually minor and often only noticeable upon close comparison. However, for discerning collectors, these details can be significant factors in their purchasing decisions. Careful examination of photographs and detailed specifications is crucial when comparing specific models from 2020 and 2021.
