Omega Speedmaster 3861 Review: The Greatest Chronograph

The first review in our chronograph spectacular is the Omega Speedmaster 3861. It had to be right? After all, aside from the Rolex Submariner, this Speedmaster may be one of the iconic watches of all time. But more on that later.
The first Speedmaster was introduced in 1957 by Omega under the CK2915 reference, more than a decade before the highly publicized 1969 race to produce the first automatic chronograph. Unlike many earlier chronographs that leaned toward aviation or dress aesthetics, the original Speedmaster was conceived as a purpose-built sports timing instrument, designed primarily for racing drivers and engineers. It was part of Omega’s broader 1957 “Professional” trilogy, launched alongside the Seamaster 300 and Railmaster, and it reflected a growing post-war fascination with speed, motorsport, and technical precision.
What distinguished the CK2915 immediately was its external tachymeter bezel. While tachymeter scales had appeared on chronograph dials before, Omega moved the scale onto a steel bezel, improving legibility and freeing the dial from clutter. This design choice would become one of the Speedmaster’s defining traits. The watch featured broad arrow hands, a symmetrical 39mm steel case with straight lugs, and a clean tri-compax layout. Inside was the legendary Caliber 321, a column-wheel chronograph movement based on a design by Lemania, prized for its smooth pusher feel and mechanical robustness.
Throughout the late 1950s and early 1960s, the Speedmaster evolved subtly. The broad arrow hands were replaced, the bezel material changed from steel to black aluminum for better contrast, and the case proportions were refined. Yet the core architecture remained consistent, such as the manual wind movement, column-wheel chronograph, tachymeter bezel, and highly legible dial. Importantly, this was still well before the automatic chronograph revolution of 1969, when brands including Heuer, Breitling, Zenith, and Seiko raced to debut self-winding chronograph movements. During that period, the Speedmaster remained resolutely manual, a detail that would later prove advantageous in environments where automatic rotors were less practical.
The turning point in the Speedmaster’s early history came in the mid-1960s when it was selected by NASA for manned space missions after a series of rigorous qualification tests. Although that chapter would ultimately cement its reputation, the foundational identity of the Speedmaster had already been established in 1957, as a robust, legible, purpose-built chronograph designed for measuring speed and elapsed time with clarity and reliability.
My Omega Speedmaster 3861 Sapphire Sandwich
Many years ago, before I purchased my iconic Omega Seamaster 300M, I acquired a rather beat up Omega Speedmaster 1861. Covered in dings and scratches, it was still one of the finest luxury pieces I had ever owned. I vividly remember watching From the Earth to the Moon and Apollo 13, feeling an unexpected sense of pride and allowing myself a small grin whenever the watch appeared on screen. It felt like owning a tangible piece of history.
Young and foolish, however, I convinced myself to let it go. I told myself I needed more water resistance and perhaps a cleaner example in better condition. The funds allowed me to purchase my first brand new luxury watch, the Seamaster 300M, and that was a special moment in its own right. Still, selling the Speedmaster left something unresolved.
It was never a watch I could truly move on from. Years later, I returned to where I began and purchased the modern Omega Speedmaster Professional 3861 Sapphire Sandwich.
It had been many years since Omega meaningfully updated the internals of the Speedmaster. The 1861 had powered the watch since the late 1990s and was itself an evolution of the 861 that dated back to the 1960s. In an era obsessed with extended power reserves, high beat rates, and ever expanding certifications, there is something charming about the Speedmaster’s measured pace of development. Each update feels deliberate and restrained, preserving a connection to its past in a way that few modern sports watches can replicate.
The METAS certified 3861 continues that tradition of incremental refinement. My sapphire version features an applied logo and the welcome return of the dot over ninety to its original position on the bezel. At 42 millimetres, the case sounds substantial on paper, yet the elegant lyre lugs allow it to wear smaller than its dimensions suggest. Water resistance remains a modest 50 metres, which is hardly impressive, though perhaps that is forgivable for a watch forever linked to the Sea of Tranquility.
The lume performs adequately, while daytime legibility is excellent. The dial is a masterclass in clarity with crisp printing, balanced subdials, restrained monochrome tones, and a handset that is both simple and highly legible. Inside, the 3861 movement offers 26 jewels, a 50 hour power reserve, and a beat rate of 21,600 vibrations per hour. Importantly, it remains relatively thin, allowing the watch to measure just over 13.5 millimetres in thickness. Paired with a 20 millimetre lug width, it makes for an exceptionally versatile everyday companion.
The bracelet deserves special mention.
When Omega introduced the 3861 generation, the bracelet received its most significant redesign in decades. The new version tapers more dramatically and features beautifully articulating links that allow it to sit comfortably and securely on the wrist. Early examples lacked on the fly adjustment, but Omega has since added a subtle push button extension of approximately 5 millimetres. It may not be the most sophisticated system on the market, yet it proves genuinely useful on a warm summer day.
All things considered, the Speedmaster remains difficult to beat. Compared with the more visually complex Breitling Navitimer, the Speedmaster is exceptionally legible in almost any lighting condition. Its bracelet is more understated, and the clasp feels far more practical than the butterfly style used by Breitling. Against the IWC Pilot’s Chronograph, the Speedmaster is noticeably thinner, which makes it better suited to daily wear. For me, it is as close to the perfect chronograph as one can reasonably expect, and it is a watch I would recommend without hesitation.
There is, however, one unavoidable drawback. The price continues to climb. I purchased mine on the secondary market in Japan for around 4,500 dollars. When the 3861 was first released, retail pricing hovered near 7,150 dollars. Today, it is much closer to 9,000 dollars. That brings it nearer to its rival, the Rolex Daytona, though acquiring one of those at retail remains a challenge in itself.
