The new Clean Factory 4131 has made waves with its latest design, particularly in the realm of the black dial variants. Enthusiasts have keenly observed the three silver sub-dials on the face, which are the most significant update in this model. The edge of these dials now features an additional luminous ring that Clean has mastered, showcasing excellent gradient and brightness. However, the intricate texture of the silver-grey sub-dials, although slightly less refined than the genuine models, is barely noticeable to the naked eye. The real difference becomes apparent under natural light comparison.

Other elements such as the indices and luminescence have also been well executed. It should be noted that Rolex has updated the cylindrical mounts for the hands post-4131, yet Clean’s four genuine samples reveal some discrepancies, such as variations in the smoothness of the indices and the use of older conical mounts for the hands. This suggests that Rolex might be clearing out stock from the 4130 era.

The case and bracelet have been compared in images and show minimal differences in overall appearance. Time was critically tight for this release, yet Clean managed to procure five authentic pieces swiftly. The watches’ value reportedly fell by over $100,000, excluding dismantled or damaged units. Upon meticulous examination and photographic comparison, I find this to be an impressive creation.

Choosing the sh4131 involves complex considerations, but it’s crucial to understand that ‘sh’ is not synonymous with inferior quality. Clean never compromises on quality for profit and has indicated that the procurement cost of the sh4131 movement is not cheaper than the dd4130. Any light-related discrepancies are addressed with natural light photos, which should be the benchmark for evaluation.
