YS Factory Rolex Label Noir Oyster Tourbillon 116400
The First Recognized Rolex Tourbillon Milgauss Conversion
1. What Makes the YS Rolex Label Noir Tourbillon So Unique?
The YS Factory Label Noir Oyster Tourbillon is developed based on the iconic Rolex Milgauss 116400 data structure.
It is widely recognized as one of the earliest Rolex-based tourbillon conversions acknowledged by international watch media.
Unlike decorative skeleton modifications, this project involved a true mechanical transformation — turning a classic anti-magnetic sports watch into a high-complication tourbillon timepiece.
Core Highlights:
• First Rolex-based big seconds tourbillon
• Developed from Cal. 3131 architecture
• Structural reengineering at movement level
• Professional-grade black PVD finishing
This is not cosmetic customization — it is a structural breakthrough.
2. How Was the 3131 Movement Reengineered?
YS watchmakers started with the base 3131 automatic movement architecture.
Engineering adjustments included:
• Removal of 51 original components
• Addition of 94 new mechanical components
• Modification of 2 key structural parts
• Integration of a large seconds Sea-Gull tourbillon module
The final result:
• True mechanical tourbillon at 6 o’clock
• Big seconds configuration
• Stable amplitude control
• Visible rotation cage performance
This marked a rare milestone in the high-end modification sector — transforming a sports Rolex into a complication-level watch.
3. Why Is the Tourbillon Positioned at 6 O’clock?
The 6 o’clock layout keeps visual symmetry intact.
Design logic:
• Focus remains on the rotating cage
• Balanced dial proportion
• Big seconds enhances dynamic motion
• Maintains Oyster identity
Instead of over-complicating the dial, the design emphasizes mechanical purity.
The “Milgauss” text at 12 o’clock is replaced with “Label Noir,” aligning with the original customization concept.
4. Case & Dial Design — From Bright Oyster to Stealth Luxury
The original Oyster brightness is replaced with stealth minimalism.
Specifications:
• 904L stainless steel base
• Black PVD coating
• Matte grey dial
• Black indices & hands
• Classic Oyster folding clasp
The result:
A dark, understated sports case that highlights the tourbillon without distraction.
The lightning seconds hand heritage remains rooted in the Milgauss identity.
5. Is This the First Rolex Tourbillon?
Historically, Rolex has never officially produced a tourbillon wristwatch.
Therefore, independent watchmakers and modification houses have explored tourbillon conversions based on Rolex architecture.
The YS Label Noir Tourbillon became widely referenced online under searches such as:
“First Rolex Tourbillon Watch”
“Milgauss Tourbillon Modification”
“Label Noir Tourbillon Rolex”
It represents a technical conversation piece within enthusiast communities.
6. Why YS Factory Is Known for Tourbillon Engineering?
YS Factory has specialized in high-complication transformation projects.
Previous tourbillon developments include:
• Roger Dubuis Excalibur Double Tourbillon style dual-balance systems
• Richard Mille RM Tourbillon inspired mechanical builds
The Label Noir Milgauss project further strengthened YS’s reputation as a complication-focused workshop.
YS positioning:
“Built for Tourbillon Innovation.”
