This replica speedmaster 311924 black 1004 is a ceramic-cased variant within the Dark Side of the Moon family, reference 311.92.44.51.01.004. At 44.25mm in black ceramic, it shares the monochrome philosophy of the original Dark Side release but incorporates subtle finishing variations that distinguish the .004 reference from its predecessor. The matte black case absorbs ambient light while the dial uses a combination of blackened indices and luminescent accents to maintain legibility. Omega designed this family specifically for wearers drawn to the Speedmaster chronograph silhouette in a modern-material execution.

Case & Movement Specs

• Case diameter: 44.25mm
• Case material: black ceramic (ZrO2)
• Dial: black with luminous markers
• Crystal: sapphire with anti-reflective coating
• Strap: black fabric or leather with ceramic clasp
• Movement: automatic co-axial chronograph
• Functions: chronograph, date, tachymeter

Ceramic cases arrive at their color during the sintering process, which means the black tone runs through the full material thickness rather than sitting on a surface coating. A scratch deep enough to be visible on steel would not reveal a different color underneath on this case, which contributes to the long-term appearance stability that ceramic provides.

Caliber Breakdown

The co-axial chronograph inside the .004 features a column wheel, a silicon balance spring, and a bi-directional winding rotor. The silicon spring makes the balance assembly virtually immune to magnetic fields up to the levels encountered in daily life, including proximity to phones and laptop speakers. This addresses one of the historical vulnerabilities of mechanical chronographs in modern environments. For a steel-cased interpretation of the same chronograph platform, consider the 329.30 steel Racing reference. Both sit under the Speedmaster umbrella but target different material preferences.

How It Compares

Within the Dark Side family, the .004 sits alongside the .003 and several color-accented variants. The distinctions between Dark Side references are often found in dial texture, luminescent color, and strap material rather than case shape or caliber. Black ceramic Speedmasters weigh noticeably less than their steel equivalents despite the larger diameter, which makes them more comfortable during extended wear. The full-dark aesthetic limits strap pairing options to dark tones, but this consistency is precisely what makes the Dark Side line appealing to collectors who value a unified visual statement. This replica speedmaster 311924 black 1004 delivers the ceramic Dark Side proposition with the specific finishing details that define the .004 variant.
