Clean Factory Rolex Sea-Dweller 126600 43mm Full 904L Black Dial

Clean Factory / C Factory Rolex Sea-Dweller 126600

43mm “Single Red” SD43 – Upgraded Engineering Edition

1. Clean Factory Re-Engineering Based on Previous Generations

The Sea-Dweller 126600 Single Red (43mm) has previously been produced by AR Factory and VS Factory.
This latest version, jointly developed by Clean Factory / C Factory, is not a simple reissue. Instead, it is a comprehensive upgrade built upon earlier generations, focusing on real mechanical function, structural refinement, and overall usability.

2. True Helium Escape Valve – No Longer Decorative

One of the most significant upgrades is the helium escape valve at the 9 o’clock position.
Unlike earlier versions where the valve was purely decorative, Clean Factory now implements a fully functional helium exhaust system. The internal exhaust components are manufactured using Grade 5 titanium alloy, achieving a true one-to-one structural restoration.

3. Enhanced Waterproof Performance

With the introduction of a functional helium escape valve and improved internal sealing, the overall waterproof performance has been significantly enhanced.
This upgrade aligns the watch more closely with the Sea-Dweller’s original professional diving purpose, rather than remaining a purely aesthetic tool watch.

4. Upgraded Bracelet Extension Buckle – Structural & Finishing Improvements

The bracelet extension buckle has been structurally revised compared to other factory versions.
Clean Factory reworked the internal structure and refined the polishing, resulting in smoother operation, improved durability, and a more solid tactile feel when extending or adjusting the bracelet.

5. Corrected 12 o’clock Luminous Pearl Color

The luminous pearl at 12 o’clock has been color-corrected.
It is no longer an incorrect bright white tone; instead, it now matches the surrounding luminous elements more naturally, significantly improving dial consistency and visual authenticity.

6. 3235 Movement – 72 Hours of Power Reserve

Powering the watch is the integrated 3235 automatic movement, offering approximately 72 hours of power reserve.
The movement structure, performance stability, and long-term reliability make it a well-matched engine for the robust Sea-Dweller 43mm platform.
