Omega Speedmaster Moonwatch Grey Side Of the Moon Manual‑winding grey dial nylon bracelet 44,25 mm

The Essence of the Moon

For more than half a century, the Speedmaster has embodied exploration and the pioneering spirit. In 1968, during the Apollo 8 mission, three astronauts approached the far side of the Moon for the first time — that world of silence and dust where the light fades softly. Upon his return, Commander Jim Lovell summed up the vision in one simple phrase: “The Moon is essentially grey.”
Those words, imbued with almost mystical restraint, still resonate today within the new Speedmaster Grey Side of the Moon 2025, which captures both the substance and the soul of that moment.

Entirely crafted from polished and satin-brushed grey ceramic, this edition pays tribute to the mineral beauty of the lunar surface. It expresses a sense of suspended time, of elegance without shine or shadow — absolute purity. Every line of its case, every shade of grey, seems to dialogue with the cold light of the cosmos.

Between Light and Starlit Dust

The Speedmaster Grey Side of the Moon 2025 captures that elusive balance between shadow and light, where every detail pays homage to Commander Jim Lovell’s vision: “The Moon is essentially grey.”

Its 44.25 mm case combines polished and satin finishes in subtly toned grey ceramic that shifts with the play of light. Thinner than ever, with a streamlined 12.97 mm profile, this new edition gains fluidity without losing the assertive presence that defines the Speedmaster.

The brushed ceramic bezel, perfectly integrated into the case, features a laser-engraved tachymeter scale filled with white Super-LumiNova, ensuring optimal readability and a discreet glow even in the dark.
Beneath the sapphire crystal, the openworked grey dial reveals the movement’s main plate, meticulously laser-engraved to reproduce the actual topography of the Moon’s surface — a technical and aesthetic feat that makes each timepiece a true fragment of the Moon on the wrist.

The tone-on-tone hands and indexes, filled with white Super-LumiNova, achieve perfect harmony between contrast and subtlety. Gone are the bright accents or overt space references: this new Grey Side of the Moon embraces pure sobriety — a monochrome design devoted entirely to the essentials: light, matter, and time.

A Caliber That Brings the Moon to Your Wrist

Through the skeletonized dial, OMEGA unveils its new Co-Axial Master Chronometer Caliber 3869. Offering a truly unique horological aesthetic, the Caliber 3869 is decorated with a lunar relief pattern, laser-engraved across its black-coated bridges and main plate. Like our satellite, the movement reveals two distinct faces: on the dial side, the Moon’s near surface as seen from Earth; on the reverse, through the caseback, the hidden far side of the Moon — the one only astronauts have ever seen. In this new iteration, the lunar landscape gains precision through a blend of laser engraving and contrasting finishes, creating remarkable visual depth and harmony.

As expected, the caliber is certified Master Chronometer and approved by METAS — among the highest standards of precision in the industry (0 to +5 seconds per day), with resistance to magnetic fields up to 15,000 gauss. It also offers a power reserve of 50 hours.

Finally, surrounding the transparent caseback, a discreet engraving recalls the words spoken by Jim Lovell during Apollo 8: “THE MOON IS ESSENTIALLY GREY.” A simple, almost meditative phrase that captures the very essence of this watch — the pure beauty of the Moon, in its silent, grey light.

Strap and Comfort

More contemporary in its appearance, the Speedmaster Grey Side of the Moon 2025 on a grey rubber strap explores a more refined dimension of lunar design. Its lightly brushed outer texture matches the satin-finished surfaces of the case, while the inner side reveals an engraved motif inspired by the Moon’s cratered surface — a discreet nod to the collection’s spacefaring heritage.

Flexible, durable, and perfectly integrated into the case, this modern material hugs the wrist with millimetric precision. It offers a perfect balance between comfort and technical performance, turning the watch into a true extension of the wearer’s body.
The folding clasp, crafted from ceramized titanium and grey ceramic, completes the ensemble with elegance, ensuring lightness, security, and durability.
A version that unites mineral aesthetics with contemporary performance — the Moon on your wrist, in its purest form.
