This replica speedmaster moonwatch 310304 carries the white-dial interpretation of the most historically significant chronograph in the Omega catalog. The 310.30.42.50.04.001 reference applies a white or silver dial to the Moonwatch Professional case, which at 42mm maintains the dimensions established by the original references that went to the moon. The omega speedmaster moonwatch has always been defined by its black dial, so this white variant offers a genuine departure from tradition while keeping every other design element intact.

Case & Movement Specs

• Case diameter: 42mm
• Case material: stainless steel
• Dial: white or silver with step dial construction
• Bezel: black anodized aluminum or ceramic tachymeter
• Crystal: sapphire (hesalite optional on some refs)
• Bracelet: stainless steel with adjustable clasp
• Movement: manual-wind chronograph
• Functions: chronograph, small seconds, 30-minute counter, 12-hour counter

The 42mm case is 2.25mm smaller than the 44.25mm Racing references, which gives the Moonwatch a tighter, more vintage-proportioned fit. Manual winding keeps the case thickness down compared to automatic chronograph calibers. On a super clone that matters, because the 3861 clone keeps the same slim caseback profile as the genuine movement.

Caliber Breakdown

Unlike the automatic chronographs in the Racing line, this Moonwatch uses a hand-wound movement. Manual winding means no rotor adding thickness to the caseback, which preserves the slim profile that defined the original Speedmaster Professional. The step dial construction adds subtle depth to the white surface by creating a slight recess for the subdials. For a completely different character within the same family, the Panda Dial 311324 plays with black-and-white contrast in a 40mm case. The full Speedmaster lineup spans from this traditional Moonwatch format to ceramic Dark Side editions.

How It Compares

White-dial Moonwatches sit in a category of their own. They carry the historical weight of the Speedmaster Professional program but present it in a colorway that reads lighter and more contemporary. The 42mm diameter keeps this from feeling oversized, and manual winding connects the daily ritual to the heritage of the caliber. This replica speedmaster moonwatch 310304 balances that legacy with a fresh dial perspective.

Frequently Asked Questions

What makes the Moonwatch Professional 42.50.04.001 unique?

The white dial distinguishes this reference from standard black-dial Moonwatch variants. The surface reads as soft silver-white in low light, brighter in direct sunlight.

Which factory produces the best Speedmaster Moonwatch Professional clone?

OM Factory leads Moonwatch production. Their white dial tone matching and Cal. 3861 clone accuracy set the standard.

Is the Moonwatch Professional automatic or manual wind?

Manual wind. The Cal. 3861 requires daily winding, maintaining the traditional Moonwatch experience from Apollo-era references. Every superclone of this reference is hand-wound as well, because Omega has never built the Moonwatch Professional with a rotor.

What case size is this replica Speedmaster Moonwatch?

42mm diameter—the standard Moonwatch Professional size since the original NASA-certified references.
