After resolving previous issues, BBR Factory upgraded its product lineup. JB Factory has captured a sizeable portion of the market with lower pricing, so let’s start with a brief factory update: limited stock available for the BBR Roger Dubuis Carbon Fiber V4 version.
Important note: the watch features an internal skeleton frame structure on the movement. Watch enthusiasts understand that the movement represents the most critical core technology of a timepiece. BBR watchmakers conducted countless experiments to break through technical barriers, allowing collectors to experience this top-grade replica tourbillon.
The frame-style skeleton double-layer bridges deliver both reliability and fine detailing. The V4 movement is further refined, adopting the exact same mechanism as the genuine RD505SQ.
The watch case has also been upgraded. Carbon fiber is a high-tech material that weighs half as much as aluminium yet boasts three times its tensile strength. The carbon fibre grain across the entire V4 case is clearer and more refined. It delivers a light, comfortable wearing experience, while its unique dark patterned texture looks exceptionally striking.
It comes with a natural rubber strap. Each strap fits perfectly against the lugs to maximize wrist comfort. The clasp uses titanium with vacuum-plated premium black finish; it is robust, durable and resistant to fading.
Roger Dubuis specializes in tourbillons and only produces the most sophisticated and captivating flying tourbillons. Since its founding, Roger Dubuis has dedicated itself to developing innovative skeleton movements, striving to create lighter, more dynamic and boldly creative modern skeleton calibers.
This Roger Dubuis Excalibur timepiece combines two superb watchmaking feats: a skeleton movement and a tourbillon. Its official reference number is DBEX0577.
Exclusively developed hand-wound movement with a 70-hour power reserve. It features hours, minutes and a genuine flying tourbillon. Compared with the prior version, the V4 boasts bright, clear perlage finishing.
All specifications match the genuine watch. It features a molded carbon fiber case, natural rubber strap and sapphire crystal. The V4 version also delivers a notable upgrade in case surface brightness compared with earlier iterations.
The skeleton dial uses hour and minute hands to display time. Both the sword-shaped hour and minute hands feature skeletonized centres, highlighted by striking red tips for clear, straightforward time reading. The V4 upgrade faithfully replicates the genuine design with a fully openworked centre of the movement, a highly difficult technical feat.
BBR’s new Roger Dubuis tourbillon watch features a carbon fiber case. Carbon fiber is an advanced high-tech material presented in timeless black with elegant, luxurious woven grain patterns. Carbon fiber is flexible externally yet rigid internally: it weighs half as much as aluminum while offering three times its tensile strength, plus excellent corrosion resistance. The V4 version applies filled paint to the crown, achieving a colour nearly identical to the genuine and retaining its hue over time.
It must be said that carbon fiber grain delivers outstanding texture. Imagine wearing a carbon fiber watch in hot summer. It offers a light and comfortable fit on the wrist. Its unique dark patterned finish looks stunning and helps you stand out effortlessly. For the V4 version, the rarely-seen grain on the case back is polished to match the front perfectly. The consistent grain on both sides creates a more pleasing visual effect.
We have previously covered how to tell a real tourbillon from a fake one: check whether the escapement rotates together with the cage. If it spins continuously through 360 degrees, it is a genuine tourbillon. If it only swings back and forth, it is a fake.
Tourbillons fascinate many watch lovers. Staring at its rotation feels like gazing into a visual vortex, utterly mesmerizing. The V4 version features enlarged ruby bearings for improved wear resistance and a longer service life.
The iconic sword-cut bezel is crafted with high-precision cutting, ensuring uniform depth and bevel angle for every notch. For the V4 version, imported precision machine tools are used to process chamfers, rounded corners and cutting edges, delivering striking three-dimensionality.
According to the specification comparison, the V4 version achieves nearly identical case diameter and thickness as the genuine timepiece. It truly realizes a 1:1 replica.
