Omega Speedmaster Grey Side of the Moon automatic 44,25 mm Full Set 2020

Speedmaster Moonwatch, the Legend of Space Exploration

Few watches can claim a history as rich as that of the Omega Speedmaster. Introduced in 1957 as a chronograph designed for drivers and motorsport enthusiasts, it quickly surpassed its original purpose to become a legend of space exploration. After successfully passing NASA’s rigorous qualification tests, the Speedmaster became the official watch for all manned American space missions in 1965.

Four years later, it accompanied the Apollo 11 astronauts during the first Moon landing in history. Since that landmark event, the Speedmaster has been universally known as the “Moonwatch” and remains one of the very few timepieces able to claim such a direct connection with one of humanity’s greatest achievements of the 20th century.

Over the decades, Omega has continuously evolved this icon while preserving its essential DNA. The “Side of the Moon” collection, unveiled in the early 2010s, opened a new chapter in this story by offering contemporary interpretations inspired by the different facets of our natural satellite. Bolder in their design, these references combine the Speedmaster’s heritage with innovative materials and cutting-edge movements, resulting in some of the most spectacular creations in the modern history of the collection.

Grey Side of the Moon, a Futuristic Interpretation of the Icon

With the Grey Side of the Moon, Omega presents one of the most refined and technically accomplished versions of the Speedmaster collection. Inspired by the mineral tones of the lunar surface, this reference combines advanced materials with contemporary design while preserving the hallmarks that have made the Moonwatch such a success.

Its 44.25 mm case is crafted entirely from grey ceramic, a material renowned for its lightness, scratch resistance, and remarkable long-term stability. This subtle hue extends to the bezel, which features a tachymeter scale executed in white Super-LumiNova, ensuring excellent legibility while reinforcing the watch’s monochromatic identity.

The true highlight of this reference lies in its exceptional sand-blasted 950 platinum dial. Its matte, textured appearance evokes the lunar landscapes that inspired the collection. Moonwatch-style hands, applied indexes, and chronograph counters create an elegant contrast while ensuring immediate readability. Remaining faithful to the historical Speedmaster architecture, the watch features a combined chronograph hour and minute counter at 3 o’clock, along with a small seconds display at 9 o’clock.

Fitted with a matching grey leather strap, this Grey Side of the Moon also benefits from a folding clasp crafted from ceramic and titanium, an exclusive detail that further emphasizes the exceptional level of finishing found throughout the watch.

Sporty, contemporary, and remarkably elegant, this Speedmaster occupies a unique place within the “Side of the Moon” collection. A modern interpretation of the Moonwatch that captivates as much through its visual presence as through the outstanding quality of its materials.

The OMEGA Co-Axial Calibre 9300

At the heart of this Speedmaster Grey Side of the Moon beats the manufacture OMEGA Co-Axial Calibre 9300, one of the most iconic automatic chronograph movements developed by the Biel-based manufacture in recent decades. Introduced to mark a new generation of integrated movements, it combines technical innovation, chronometric performance, and high-end finishing.

Visible through the bevelled sapphire crystal caseback, this automatic calibre reveals a particularly modern architecture. Its column-wheel chronograph with vertical clutch ensures precise and smooth operation of the chronograph functions, while the combined chronograph hours and minutes display within a single counter at 3 o’clock significantly enhances the readability of elapsed times.

The Calibre 9300 also benefits from the Co-Axial escapement developed by George Daniels and industrialized by OMEGA, a technology designed to reduce internal friction and improve long-term performance stability. Combined with a Si14 silicon balance spring, it offers excellent resistance to magnetic interference as well as remarkable day-to-day reliability.

Equipped with twin barrels mounted in series, the movement delivers an impressive 60-hour power reserve, allowing the watch to remain running for several days when not worn. Its refined finishing, including bridges decorated with OMEGA’s distinctive “Arabesque Geneva Waves” pattern, reflects the exceptionally high level of craftsmanship invested in this manufacture movement.
