This replica speedmaster moonwatch 311934 takes the Speedmaster Moonwatch concept into a 44.25mm ceramic case with a white dial, creating the reference known informally as the “Moonlight” or “Grey Side of the Moon” white edition. The 311.93.44.51.04.002 uses a ceramic case rather than steel, which changes both the weight and the scratch resistance compared to the standard Professional. Omega finishes the grey ceramic with a matte surface that absorbs light rather than reflecting it, producing a muted look that works well against the bright white dial.

Case & Movement Specs

• Case diameter: 44.25mm
• Case material: grey ceramic
• Dial: white with grey sub-dials
• Crystal: sapphire with anti-reflective coating
• Strap: grey leather with ceramic foldover clasp
• Movement: automatic co-axial chronograph
• Functions: chronograph, date, tachymeter

The grey ceramic case resists scratching far better than stainless steel and maintains its surface finish over years of daily use. Unlike the Dark Side of the Moon editions in black ceramic, this Moonlight version uses a lighter grey tone that opens up the overall palette and pairs naturally with a wider range of strap colors.

Caliber Breakdown

Omega equips the 311.93 with a co-axial chronograph caliber featuring a column wheel and silicon balance spring. The co-axial escapement reduces friction between contact surfaces, which extends service intervals compared to traditional Swiss lever escapements. A date complication at 6 o’clock adds daily functionality without cluttering the chronograph registers. For a steel-cased alternative with a similar co-axial movement, the grey-dial 329.32 reference provides the same automatic chronograph in a more traditional material. Both sit within the broader Speedmaster collection, which spans manual-wind classics through modern ceramic editions.

How It Compares

Ceramic Speedmasters occupy a different segment than the steel Moonwatch Professional. They weigh less on the wrist, feel warmer to the touch than metal, and resist the desk-diving scratches that mark up stainless-steel cases within months. The 44.25mm diameter makes this a larger watch, but the matte ceramic finish avoids the visual amplification that polished steel would create at this size. The grey-and-white palette avoids the stealth look of the all-black Dark Side editions, keeping legibility high and the mood approachable. This replica speedmaster moonwatch 311934 puts ceramic Speedmaster technology into an everyday-wearable format with lighter visual weight than its darker siblings.
