Introduction
In the replica watch industry, movement upgrades and replication accuracy have consistently served as the core benchmarks for assessing craftsmanship. Clean Factory’s (C Factory) newly released upgraded Yacht-Master 126622 in grey now incorporates the optimized ‘New Shanghai 3235’ automatic movement. This iteration demonstrates improvements in both stability and fidelity compared to its predecessor.This analysis will objectively evaluate four key aspects:Exterior detailing,Movement performance,Authenticity comparison,etc.
Exterior Comparative
Two models were evaluated – the 126622-0001 and 126622-0002. Overall, both demonstrate high fidelity to genuine counterparts.
126622-0001 (Grey Dial):The genuine grey watch (left specimen) demonstrates slight chromatic aberration against Clean Factory’s reproduction when photographed under softbox lighting due to spectral interference. However, uncontrolled natural light assessment confirms ≥95% visual congruence – subsequent documentation will provide uncontrolled lighting comparisons for verification.
126622-0002 (Blue Dial):The blue dial of the Clean factory is a little lighter, but the overall deviation is not too big. The radial pattern adopts the same PVD electroplating process as the genuine product, and the RGB color value is on the same basis. The advantage of this PVD electroplating process is that it can ensure that the color of the shipment will not cause color differences due to different batches.
The bezel is made of electroplated PVD platinum + anti-fingerprint coating, and the bezel material is changed from ordinary brass to fine steel. In other words, even if the bezel is bumped and the electroplating layer is damaged, the base color is the same as platinum. And the hardness of fine steel is higher than that of ordinary copper.

Case Detail Comparison
Left And Right Sides Case Comparison
The curvature and shape maintain 100% similarity, also utilizing 904L stainless steel material.

Case Back Comparison
Fundamentally identical, the case back seamlessly integrates with the case body featuring a subtle convex curvature at the base – one of the distinctive design characteristics of Yacht-Master cases.

Crown Comparison
The crown Three-dimensional effect, and three-point arrangement of arc. The size and shape are consistent.

Case and Bracelet Connection Comparison
The integration between case and bracelet demonstrates identical curvature profiles – dual concave bends with central convex elevation – showcasing Clean Factory’s exceptional attention to micro-engineering details.

Case Side Engravings Comparison
The bilateral engravings have been precisely replicated by Clean Factory with micron-level accuracy, achieving indistinguishable reproduction quality from the original.

Dial Details Comparison
Dial Font Comparison
The overall font tone demonstrates striking similarity in both chromatic fidelity and dimensional projection, achieving parity with the original specifications.


Hands Comparison
The overall appearance of the hands closely resembles the genuine product, though the images reveal a discernible variance in the hour hand’s thickness.


Index Marker Comparison
The chamfer polishing of the indices is nearly identical to the original. Clean Factory applies an additional white gold plating layer after nickel electroplating, enhancing the indices’ dimensional fullness and visual brilliance.

Strap Comparison
The bracelet is crafted from 904L stainless steel. Clean Factory has meticulously refined every detail – from the precise chamfering and polishing to the engineered opening/closing resistance and tactile feedback during operation.


Analysis Under Natural Lighting Conditions Comparative
Under natural lighting conditions, the overall appearance is virtually identical—both the dial color and bezel demonstrate exceptional replication accuracy.


New Shanghai 3235 movement
Upon removing the caseback, you’ll observe C Factory’s upgrade to the latest Shanghai Jinghe Caliber 3235 movement. The primary enhancement lies in its 70-hour power reserve – achieving parity with genuine specifications– representing a 30-hour improvement over previous Shanghai 3235 iterations. This eliminates weekend manual winding requirements while maintaining operational reliability. Timekeeping accuracy and stability have been validated through controlled chronometer testing (±5 sec/day) under ISO 3159 standards.



Conclusion
For enthusiasts prioritizing movement longevity and case detailing, Clean’s upgrade positions this replica firmly in the “super clone” tier—falling short only under macro scrutiny. The Shanghai 3235’s performance justifies its adoption over previous iterations.
