Rolex Submariner, often fondly called the “Sub,” has long been a benchmark in luxury dive watches, famed for its robust build, timeless design, and exceptional durability. Recently, Clean Factory (known as “C Factory”) has stepped into the spotlight, becoming a frontrunner in the replica watch industry by meticulously replicating Rolex designs. Among its offerings, the 40mm Rolex Submariner with the 3135 movement stands out prominently. This review dives deep into the watch’s materials, craftsmanship, movement reliability, and overall value.
- Classic Design and Perfect Proportions
Clean Factory Submariner faithfully retains the classic 40mm size that has long been favored by watch enthusiasts for its ideal blend of wrist presence and wearability. The 904L stainless steel case mirrors Rolex’s original material choice, known for superior corrosion resistance and a refined finish. Its alternating polished and brushed surfaces highlight the craftsmanship, providing an authentic look and luxurious feel.
The unidirectional rotating bezel is crafted from robust ceramic, with laser-engraved numerals and markers filled with platinum-grade coating, ensuring long-lasting brightness without fading. Its action is smooth yet precise, offering excellent tactile feedback similar to the original Rolex Submariner.
- Attention to Detail: From Dial to Bracelet
The dial, a central feature of any Rolex, is impeccably replicated. The sapphire crystal, scratch-resistant and with anti-reflective properties, allows for clear viewing under various lighting conditions. At the six o’clock position, a subtle laser-etched Rolex crown adds authenticity, visible only from specific angles—just like the genuine Submariner.
Super-LumiNova luminous coating on the hands and markers ensures bright and sustained visibility in darkness. The luminous fill is even, precise, and fully aligned with Rolex’s standards. The date magnification (cyclops lens) accurately replicates the original’s 2.5x magnification, with sharp date display and no distortion.



The bracelet is equally impressive. Crafted from solid 904L stainless steel, it features Rolex’s iconic Oyster design. The clasp mechanism operates smoothly and securely, incorporating micro-adjustment capability to fit wrist sizes ranging from 160 to 220mm comfortably.
- The Heart of the Watch: Reliable 3135 Movement
At its core, this Submariner houses the reliable Dandong 3135 automatic movement, recognized as one of the most dependable replica movements available. Testing revealed an impressive 72-hour power reserve, consistently maintaining accuracy within ±12 seconds per day—a significant advantage compared to other replicas.
The movement also features enhanced anti-magnetic capabilities, thanks to its silicon hairspring, ensuring stable timekeeping even when exposed to typical magnetic fields generated by electronic devices. Its shock resistance is noteworthy, with no accuracy deviation detected after vigorous movement.
- Practicality and Long-term Durability
Water resistance, crucial for dive watches, has been tested and verified to withstand pressures up to 300 meters. The sealed crown and gasket effectively prevent water ingress, although it’s advised to avoid prolonged exposure to hot water to preserve ceramic bezel integrity.
Maintenance requirements are minimal; the robust 3135 movement is easily serviceable, significantly reducing long-term care costs compared to other replicas. Regular check-ups every two years are recommended to maintain optimal performance and extend lifespan.
Who Should Consider This Watch?
- Dive Watch Enthusiasts: Perfect for those seeking authentic Rolex Submariner styling with practical diving capability.
- Movement Aficionados: Ideal for individuals who value precise, reliable performance from the 3135 movement.
- Value-oriented Collectors: Offers exceptional build quality and authentic details at a fraction of the genuine Rolex price.
Final Verdict
The Clean Factory Rolex Submariner Black Dial with the 3135 movement represents a standout choice within the replica watch market. It strikes an impressive balance of authenticity, durability, and affordability. While minor nuances distinguish it from the original Rolex, its overall build quality, reliability, and attention to detail make it an exceptional choice for watch enthusiasts who demand quality and precision without the premium price tag.
