The Omega Speedmaster Professional Moonwatch. A name synonymous with space exploration, legendary reliability, and timeless design. For decades, this iconic chronograph has captivated watch enthusiasts and cemented its place in horological history. While the 42mm case size has become the standard, Omega has periodically revisited the Speedmaster's heritage, offering variations that cater to a broader range of wrist sizes and preferences. This article delves into a particular iteration, the Omega Speedmaster Anniversary Series Chronograph in a more compact 39.7mm case, exploring its design, mechanics, legacy, and place within the wider Omega Speedmaster family.
The 39.7mm Omega Speedmaster Anniversary Series Chronograph represents a compelling alternative for those who appreciate the classic Speedmaster aesthetic but prefer a slightly smaller case size. This subtle reduction in dimensions makes the watch remarkably versatile, suitable for both formal and informal occasions, and comfortable on a wider range of wrists. Crafted from high-quality stainless steel, the watch exudes an understated elegance that belies its robust construction and impressive heritage. The striking black dial, a hallmark of the Speedmaster design, is perfectly complemented by the 39.7 x 47.0 mm case dimensions, creating a balanced and visually appealing timepiece.
A Deep Dive into the Design:
The design of the 39.7mm Omega Speedmaster Anniversary Series Chronograph is a masterful exercise in restraint and classicism. It meticulously adheres to the core design principles of the original Speedmaster Professional, retaining the iconic features that have defined the model for generations. The black dial, with its distinct sub-dials, luminous hands, and applied indices, is instantly recognizable. The tachymeter scale, engraved on the bezel, adds a functional element, allowing the wearer to measure speed or distance. The hesalite crystal, known for its scratch resistance and unique appearance, further enhances the watch's vintage appeal. The caseback, often featuring the iconic Speedmaster emblem, showcases the intricate workings of the movement.
The subtle difference in case size, compared to the more common 42mm models (including the Omega Speedmaster 42mm and even the Omega Speedmaster 43mm chronograph variants), significantly impacts the watch's overall feel on the wrist. The 39.7mm version offers a more delicate and refined presence, making it an ideal choice for individuals with smaller wrists or those who prefer a less imposing timepiece. However, it doesn't compromise on the robustness and durability associated with the Speedmaster name. The stainless steel construction ensures longevity and resistance to everyday wear and tear.
The Heart of the Speedmaster: Omega Caliber 1861
Powering this remarkable timepiece is the legendary Omega Caliber 1861, a manual-winding chronograph movement that embodies the spirit of precision and reliability. This movement is a direct descendant of the caliber used in the original Speedmaster Professional watches that accompanied astronauts on their lunar missions. Its robust construction and proven performance have made it a benchmark in the world of mechanical watchmaking.
The manual-winding mechanism adds a unique tactile experience to the watch. The act of winding the crown is a ritualistic connection to the watch's mechanical heart, a reminder of the craftsmanship and engineering that went into its creation. While requiring regular winding, this process also allows for a deeper appreciation of the watch's inner workings and its connection to the history of mechanical watchmaking. The manual-winding movement is also known for its simplicity and robustness, factors contributing to its remarkable reliability.
