Description
DIWF Rolex Daytona IRBIS Quartz Fiber Custom
A precise execution of the avant-garde DiW modification, leveraging advanced composite materials and the proven 4130 clone architecture.
Powered by 4130 Clone Caliber
The movement architecture mirrors the genuine Rolex caliber with a fully integrated chronograph module, avoiding the thickness and unreliability of modular Dubois Dépraz or 7750 alternatives. It utilizes a free-sprung balance and precise regulation, ensuring crisp pusher feedback and reliable reset-to-zero functionality. The vertical clutch guarantees smooth seconds hand engagement without the initial jump common to horizontal clutch systems.
±5–8 s/day (Standard regulation for this specific 4130 clone batch).
- ✅ Power Reserve: Approximately 36 hours
- ✅ Complications: 12-hour chronograph, 30-minute counter, running seconds
- ✅ Winding Direction: Bidirectional automatic winding
Technical Specifications
Weighing approximately 55 grams, the 41mm case features a 12.5mm thickness, mirroring the standard Daytona profile but executed entirely in layered quartz fiber for an ultra-lightweight tactile experience.
The monochromatic base utilizes high-contrast registers and crisp typography, accented by custom dial text that aligns with the aftermarket design language. Lume application remains consistent and evenly distributed.
The fixed tachymeter scale is machined directly into the composite, exhibiting the natural striations of the layered material. Engravings are deep and adequately filled.
Constructed from tactical fabric with reinforced stitching, the strap utilizes a hook-and-loop closure system tailored for active wear and precise sizing adjustments.
Why DIWF for This Reference?
Many collectors ask: “Why not Clean Factory?”
While Clean Factory produces the definitive standard Oystersteel Daytona, DIWF specializes exclusively in aftermarket DiW modifications. Their proprietary mastery of quartz fiber and carbon composites ensures the case weight and tactile feel closely mimic the genuine modified piece, a highly specific niche that standard factories do not address.
Full Disclosure: The layered quartz fiber pattern is unique to each individual block during machining, meaning the visual striations on your specific watch will never universally match promotional photos or the exact grain of the genuine prototype.

Collector Q&A
Q: Does the quartz fiber case scratch easily compared to 904L Oystersteel?
A: Quartz fiber is highly resistant to standard hairline scratching but is more prone to blunt-force chipping or shattering than stainless steel. It should be worn with mindfulness regarding hard impacts.
Q: Are all three chronograph sub-dials fully functional on this DIWF model?
A: Yes. Because this model utilizes the 4130 clone movement rather than a decorative 7750, the 3 o’clock and 9 o’clock totalizers work exactly as genuine, along with the running seconds at 6 o’clock.
Q: Is the case weight accurate to the genuine DiW IRBIS?
A: Yes, the use of genuine quartz fiber composite brings the total weight down to approximately 55 grams, accurately reflecting the ultra-lightweight nature of the authentic modified piece.
Q: Why does the case pattern look slightly different from the QC pictures of other buyers?
A: Quartz fiber is manufactured in layered blocks before being CNC milled. Consequently, the specific striated black-and-white pattern on every individual case and bezel is entirely unique, much like forged carbon or wood grain.
