Key Upgrades in the JB Factory Version

The upgraded JB Factory release (white shell RDDBEX0393, gold shell RDDBEX0392) introduces several refinements that elevate its authenticity:

Movement Skeletonization: The skeletonized bridges now contain no superfluous gears, closely mirroring the original architecture. This distinguishes it from standard imitations, ensuring a more accurate visual representation.
Tourbillon Balance Wheel: The balance wheel incorporates the same counterweight pegs as the genuine, a costly addition that enhances both precision and visual appeal. The Geneva Hallmark at 3 o'clock has been switched from white oil-filled to steel, aligning with the original.
Fishscale Wash: The movement's skeleton features a re-upgraded fishscale finish, now subtler and more evenly arranged, approaching the texture of the authentic piece.
Winding Clutch: The upper clutch mechanism now sports a gunmetal color with pronounced chamfering, improving the overall aesthetic.
Bottom Cover: The steel ring on the caseback bears a unique identification number, preventing watch clashes and adding a layer of exclusivity.

This is among the most intricate skeleton tourbillon watches ever produced. It syncs all structural elements of the genuine RD505SQ one-piece tourbillon movement, including the flywheel balance wheel weights and screws, achieving a movement similarity of 98%. Every component is accounted for—no missing parts, no extra gears—as verified against official diagrams. The sapphire crystal is scratch-resistant, and the original-style folding buckle completes the package. The watch exudes a domineering, trendy, and cool character, appealing to those with a bold sense of style.
