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 Dark Side of the Moon family, where it sits as the Vintage Black reference.

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 two-register layout of the 9300 family: central chronograph seconds, a combined 12-hour and 60-minute counter at 3 oclock, and running small seconds at 9 oclock. 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 base Dark Side of the Moon keeps a plain black-on-black treatment, the Vintage Black gives the same ceramic case its own dial finish. 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.

Frequently Asked Questions

What makes the Speedmaster 44.51.01.006 different?

Full ceramic case construction in black matte finish. Lighter than steel with superior scratch resistance.

Which factory makes the best ceramic Speedmaster clone?

OM Factory. Ceramic has to be shaped before sintering and then diamond-finished, which is why most factories end up with a case that reads either glossy or chalky; OM’s 44.51.01.006 holds the flat matte of the original.

Is this super clone Speedmaster Chronograph automatic?

Yes. The Cal. 9300 clone provides automatic winding with 60 hours power reserve.

How durable is the ceramic case?

Ceramic rates 1,400 Vickers hardness—highly scratch resistant. However, ceramic can crack from severe impacts unlike steel.
