This replica speedmaster 311924 represents the ceramic-cased chronograph format in the Speedmaster range, using the 311.92.44.51.01.006 reference. The all-ceramic construction means the case, bezel, and pushers share a consistent dark finish that steel and gold versions cannot achieve. At 44mm, this is a full-size chronograph built for visibility on the wrist. Where most Speedmaster references rely on stainless steel for their cases, this one uses black ceramic throughout, placing it in the same material family as the Dark Side of the Moon but with its own distinct reference identity.

Technical Overview

• Case diameter: 44mm
• Case material: black ceramic
• Bezel: ceramic tachymeter with contrasting markings
• Dial: black matte
• Crystal: sapphire
• Strap: textile or rubber
• Movement: automatic chronograph
• Functions: chronograph, date, small seconds

Ceramic cases bring measurable advantages over steel: higher scratch resistance, lighter weight at equivalent dimensions, and color permanence. The 311924 reference benefits from all three, which makes the 44mm size feel more manageable than an equivalent steel chronograph.

Inside the Movement

The automatic chronograph caliber inside the 311924 handles the standard three-register layout with central chronograph seconds, a 30-minute counter, and a 12-hour totalizer. The automatic winding rotor keeps the movement charged through daily wear, eliminating the manual winding ritual required by traditional Moonwatch calibers. For a contrasting approach, the Speedmaster Black 311924 1005 shares the same case architecture but with different dial detailing. Both are part of the Speedmaster range, positioned as the ceramic alternatives to the steel core collection.

What Sets It Apart

The 311.92 prefix identifies ceramic-cased Speedmasters, and the .01.006 suffix distinguishes this specific dial and strap configuration from other variants in the ceramic line. Where the Dark Side of the Moon carries a themed name and NASA connection, this reference operates as a straightforward ceramic chronograph without commemorative backstory. That makes it the utilitarian choice for anyone who wants the material benefits of ceramic in a pure chronograph package. This replica speedmaster 311924 delivers that ceramic construction in its most direct form.
