Omega’s 329.33.44.51.04.001 reference takes the Racing Chronograph format and pairs it with a white dial that separates this replica speedmaster racing 329334 from the darker options in the sub-line. The white face against stainless steel creates high legibility with strong contrast between the applied markers and the bright background. At 44.25mm, it runs marginally larger than the standard 44mm Speedmaster cases, though the difference is almost imperceptible on the wrist. This is the Racing variant for buyers who want maximum dial contrast.

Build Details

• Case diameter: 44.25mm
• Case material: stainless steel
• Dial: white with dark subdial registers
• Bezel: ceramic with tachymeter scale
• Crystal: domed sapphire
• Strap: leather with deployant buckle
• Movement: automatic chronograph
• Functions: chronograph, date, tachymeter

The ceramic bezel on the 329334 marks an upgrade over earlier Racing editions that used aluminum inserts. Ceramic holds its color permanently and resists scratching, which keeps the tachymeter scale legible over years of wear.

What Collectors Notice

White-dial chronographs have a different visual rhythm than dark dials. The subdial rings become the dominant design element because they contrast sharply against the white background, pulling your eye across the face. The omega speedmaster racing replica community values this ref for its readability and its departure from the all-black norm. On a leather strap, the 329334 leans slightly dressier than bracelet-mounted Racing models. For a blue-dial alternative in the Professional line, the Professional Blue Dial 329304 takes a different approach to color. Both sit in the Speedmaster collection, but they serve different aesthetic preferences entirely.

This vs Other Versions

Within the Racing sub-line, the white dial stands out because most Racing references default to grey or black. The 44.25mm case, ceramic bezel, and leather strap combination reads more versatile than the full-steel variants, making this a strong option for rotation between casual and dressed-up settings. This replica speedmaster racing 329334 offers that white-dial clarity with the full chronograph toolkit intact.
