Reference 329.30.44.51.01.001 positions this replica speedmaster 329304 in the Racing chronograph family with a black dial and a full stainless-steel bracelet. The 44.25mm case carries the same dimensions as the leather-strap Racing variants, but the integrated steel bracelet changes the weight balance and visual presence significantly. The tachymeter bezel uses a ceramic insert with liquid-metal filled numerals, and the two chronograph registers sit at 3 and 9 o’clock in the layout the Cal. 9900 uses. A date window at 6 o’clock adds daily utility below the running-seconds and chronograph registers.

Key Specifications

The steel bracelet adds roughly 30-40 grams over the leather strap equivalent, shifting the 329.30 from a sport-leaning configuration into a more substantial all-purpose chronograph. The clasp uses a push-button release with fine adjustment, accommodating wrist size changes through the day without tools.

Design & Finishing

Steel-on-steel Speedmaster Racing references offer the most self-contained package in the sub-line because they eliminate the need for strap matching or replacement. The brushed finish on the bracelet outer links contrasts with polished center links, a pattern consistent across Omega’s current bracelet designs. The black dial maintains high contrast against the steel surroundings, making the chronograph registers and hour markers easy to read in any lighting condition. A good superclone has to get that contrast right, because a flat black dial reads cheap in photographs. For a similar movement inside a lighter-colored dial, compare against the 310.32 silver-dial Moonwatch, which approaches the same chronograph brief from the heritage Professional angle. Browse the Speedmaster catalog to compare bracelet and strap configurations across all current references.

On the Wrist

The 329.30 on steel bracelet sits firmly in the daily-wear chronograph category. The bracelet distributes the 44.25mm case weight evenly across the wrist, making it feel more balanced than its diameter might suggest. Unlike leather straps that require seasonal rotation or replacement, the steel bracelet handles moisture, temperature shifts, and general wear without degradation. The black dial and steel case combination keeps the watch versatile across dress codes, from weekend errands to weekday meetings. This replica speedmaster 329304 delivers the Racing platform in its most complete and self-contained form for daily rotation. As super clone Racing references go, the steel-bracelet 329.30 is the one that needs no extra strap budget.

Frequently Asked Questions

What makes the Speedmaster 44.51.01.001 Racing series?

The 329 reference series features motorsport-inspired design, automatic movement, and larger 44.25mm case compared to classic Moonwatch.

Which factory makes the best Speedmaster Racing clone?

HR Factory (HRF) leads Racing series production. Their 329 reference clones achieve accurate proportions and finishing. On the 329.30 the bracelet is the giveaway: link taper, brushing direction, and clasp tolerance separate an HRF build from a generic Speedmaster copy.

Is this replica Speedmaster automatic?

Yes. Cal. 9900 clone provides 60 hours power reserve with automatic winding.

How does Racing differ from Moonwatch Professional?

Larger 44.25mm case, automatic movement, date function, and motorsport-inspired bezel design distinguish Racing from classic Moonwatch.

Does the 329.30 bracelet size without removing links?

The folding clasp has a fine-adjustment slide that covers about half a link, which is enough for day-to-night wrist swelling. Past that you remove links with a pin tool. Sizing instructions ship with the watch.
