This replica speedmaster 329324 brings the Racing chronograph concept into a full-size 44.25mm package with a black dial and tachymeter bezel. The 329.32.44.51.01.001 reference sits in the Speedmaster Racing sub-line, designed for motorsport timing rather than space heritage. Its case rides on a leather strap with contrast stitching, and the date window at 6 o’clock keeps it practical for daily wear. The column-wheel chronograph movement handles start, stop, and reset through pushers at 2 and 4 o’clock, with running seconds at 9 and elapsed minutes and hours split across two registers.

Key Specifications

• Case diameter: 44.25mm
• Case material: stainless steel
• Dial: black with tachymeter scale on bezel ring
• Crystal: sapphire with anti-reflective coating
• Strap: leather with folding clasp
• Movement: automatic chronograph
• Functions: chronograph, date, tachymeter

The tachymeter bezel uses a ceramic insert with liquid-metal numerals, a technique Omega introduced to improve contrast and durability over printed scales. The three sub-dials are arranged in the standard tri-compax layout that has defined Speedmaster chronographs since the 1960s.

Design & Finishing

What separates the Racing variants from the Moonwatch line is the emphasis on legibility at speed. The oversized Arabic numerals at 3, 6, and 9 replace the stick markers seen on Professional models, and the central chronograph seconds hand wears a bright orange tip for quick elapsed-time readings. Omega positions this reference between the heritage Professional and the modern co-axial chronograph models. For a closer look at how this line compares to a more traditional execution, see the silver-dial 310.32 reference. The full Speedmaster lineup covers everything from manual-wind classics to these automatic racing variants.

On the Wrist

At 44.25mm the 329.32 wears larger than the standard 42mm Moonwatch, but the curved lugs pull the case closer to the wrist and keep it from feeling unwieldy. The leather strap makes it lighter and more breathable than the bracelet versions, which suits warmer weather or active use. Whether you reach for it during a weekend track day or as an everyday chronograph, the Racing design maintains its readability at a glance. This replica speedmaster 329324 delivers the motorsport spirit of the Speedmaster range in a format built for regular rotation.
