Bokey TimeHello everyone, I am Bokey. In this comparative review, I bring you the BBR Factory Roger Dubuis Excalibur Hommage series RDDBEX0479 with a titanium case, comparing the V3 version and the V4 upgraded version to see what has been upgraded in the V4 version? The left side is the BBR Factory V3 version, and the right side is the BBR Factory V4 upgraded RDDBEX0479. Below, I will explain the specific upgrade points to watch enthusiasts through some detailed comparisons.
From multiple angles, both versions are equipped with the Seagull customized RD505SQ manual winding movement. We can observe that the movement bridges and fish scale pattern polishing of the V4 version are finer and shinier than those of the V3 version.
Both feature a titanium case, sapphire crystal glass, and a German-imported natural rubber strap.
The V4 upgraded version uses imported precision machine tools for processing and cutting in all aspects of chamfers, rounded corners, and edges, with super strong three-dimensionality! Additionally, the polishing on the main bridge is brighter than that of the previous V3 version.
Another upgrade point is the improvement in the middle of the movement bridge. We can see that the V4 upgraded version is completely synchronized with the authentic model, achieving a fully hollowed-out design in the middle of the movement, which is extremely challenging.
The tourbillon jewels of the V4 upgraded version have also been strengthened and enlarged, making them more wear-resistant and bright!
Comparison of the crowns: The crown craftsmanship of the V4 upgraded version has also been improved. The sandblasting texture features uniform particles, which are very fine and closer to the original. Here is a brief introduction to the materials of BBR’s new Roger Dubuis titanium case tourbillon watch. It uses high-strength titanium alloy material with a density of approximately 4.51g/cm³, which is only 60% that of steel. The specific strength (strength/density) of titanium alloy is much higher than other metallic structural materials, and it has good corrosion resistance. Titanium alloy works in a humid atmosphere and seawater medium with corrosion resistance far superior to stainless steel; it has particularly strong resistance to pitting corrosion, acid corrosion, and stress corrosion; and it has excellent corrosion resistance to alkalis, oxides, chlorine-containing organic substances, nitric acid, sulfuric acid, etc.
Size comparison: The BBR Factory V4 version of the Hommage series tourbillon has upgraded the case thickness. The previous V3 version was 14mm, while the current V4 upgraded version is 13.5mm. After this upgrade, both the case diameter and thickness are consistent with the authentic model.
Back comparison: The movements of both versions use an integrated tourbillon movement with six-directional precise adjustment, offering a power reserve of up to 50 hours. The V4 version has upgraded the polishing of the main bridge. We can see that the polishing of the V3 is slightly duller, while the V4’s pattern polishing is brighter, echoing the front polishing. Additionally, the main bridge wheel gaps of the movement are consistent with the original, and each movement has a unique serial number (synchronized with the original).
Summary: In conclusion, it can be seen that BBR Factory is making every effort to improve shortcomings, making details more perfect and closer to the authentic model. Regarding the issue of authenticity, Bokey is honest—there is no such thing as being identical to the authentic product. However, in terms of craftsmanship and restoration, the BBR Factory V4 upgraded Roger Dubuis Excalibur Hommage 0479 Tourbillon is currently the highest version in the replica market. Watch enthusiasts need not worry about version issues, as the manufacturer will discontinue previous versions after upgrading to V4, which can be assured! This comparison only clarifies some doubts of watch enthusiasts, and the selling price of the V4 upgraded version is the same as that of the V3 version—no price increase will be taken advantage of, which shows that BBR Factory is quite conscientious in this regard.
