Q-Factory V9 Daytona 126528 Le Mans 100th Anniversary �� 18K Yellow Gold
The yellow gold Le Mans edition addresses the historical tactile limitation of precious metal Daytona replicas through the same tungsten-core V9 platform: ~170g construction, JH4132-FS free-sprung movement correct to the exhibition caseback, and the genuine 24-hour Le Mans complication �� finished in double-layer 18K yellow gold PVD.
JH4132-FS �� Free-Sprung Calibre 4132 Clone
All Q-Factory V9 Le Mans variants share the JH4132-FS movement platform: an SH-base movement modified with a free-sprung balance wheel and bridge geometry that replicates the genuine Calibre 4132 architecture. Unlike the standard 4130 clone, the JH4132-FS carries no visible regulator pins on the balance wheel. This distinction is critical for the Le Mans reference specifically �� its sapphire exhibition caseback makes the movement permanently visible, and a standard regulated balance is an immediate identification point through the caseback. The JH4132-FS eliminates this entirely.
The dedicated gearing converts the 9 o��clock sub-dial to a true 24-hour chronograph counter, not the 12-hour totalizer of all standard 4130 Daytona clones. The column-wheel architecture and vertical clutch deliver crisp pusher engagement throughout. Units pass through for reset alignment and amplitude before dispatch.

Technical Specifications
Tungsten-Core 904L Steel �� 18K Yellow Gold PVD
40mm diameter, ~170g weight via tungsten-injected 904L steel wrapped in a 5-mil double-layer 18K yellow gold PVD. Sapphire exhibition caseback mirrors the genuine Le Mans specification. Alternating brushed and polished surface finishing.
Paul Newman Reverse Panda
Deep black sunburst main dial with contrasting white/cream sub-dials and gold-tone track markings. Vintage square-tipped ��Newman�� hash markers on sub-dials. Chromalight indices ensure low-light legibility.
Black Cerachrom Ceramic

Tungsten-Core Oyster �� 18K Yellow Gold PVD
Center links feature stainless steel shells encasing tungsten cores, allowing the yellow gold PVD to adhere to steel rather than bare tungsten �� ensuring finish durability under daily wear. Solid end links mate precisely with the case lugs. Oysterlock safety clasp with 5mm Easylink extension.
Why Q-Factory V9 for This Reference?
Many collectors ask: ��Why not Clean Factory?��
Clean Factory��s gold-coloured Le Mans uses standard hollow 904L steel at approximately 140g �� immediately detectable on handling. The Q-Factory V9��s tungsten-core construction achieves ~170g, substantially bridging the density gap toward the genuine solid gold piece at 200g+.
The second differentiator is the JH4132-FS. Through the exhibition caseback, a standard regulated balance would show its regulator pins immediately. The JH4132-FS��s free-sprung architecture and correct bridge geometry hold up to close caseback inspection without an obvious tell.
Full Disclosure: The 5-mil yellow gold PVD wrap is highly durable but will reveal the steel tone beneath at any deep scratch or gouge. Under harsh fluorescent lighting, the PVD may read marginally different in tone from genuine 18K Rolex yellow gold �� a trade-off inherent to all PVD-finished pieces.

Collector Q&A
Q: Why does this Daytona have a sapphire exhibition caseback?
A: The genuine Le Mans Daytona is the only modern Rolex Daytona with an exhibition caseback �� because the Calibre 4132��s free-sprung balance is a distinctive visual feature intended to be seen. The Q-Factory V9 replicates this across all Le Mans variants. The JH4132-FS movement is architecturally necessary here: a standard regulated balance wheel reveals its regulator pins through the caseback immediately. The JH4132-FS��s free-sprung design has no such visible pins.
Q: Does the 9 o��clock sub-dial function as a true 24-hour counter?
A: Yes. The JH4132-FS features the bespoke gearing to track a full 24-hour cycle at the 9 o��clock totalizer. This is the defining Le Mans complication, absent from all standard 4130 Daytona super clones.
Q: How does the ~170g weight compare to the genuine yellow gold Daytona?
A: The genuine solid 18K yellow gold Daytona exceeds 200g. Standard steel replicas sit at approximately 140g �� a significant and immediately noticeable difference on the wrist. The Q-Factory V9��s tungsten-core construction at ~170g closes this gap substantially, delivering a wrist presence that standard steel cannot replicate.
Q: Is the yellow gold PVD prone to fading with regular use?
A: The double-layer 5-mil PVD process is highly resistant to oxidation, everyday friction, and perspiration. Deep scratches or impacts will expose the darker steel tone beneath. With normal daily wear and basic care, the finish maintains its appearance well over extended periods.
Q: What is the main technical limitation of this edition?
A: At ~170g the V9 remains lighter than the genuine solid gold piece at 200g+. The 5-mil PVD may also read marginally different in hue from genuine 18K Rolex yellow gold under certain lighting conditions �� both are disclosed characteristics of PVD-finished precious metal replicas at this price point.
