The focal point of interest in our comparison photos is the dial’s three silver sub-dials. The most significant update in the 4131 model includes an added bright ring on the edge of these sub-dials, a detail Clean Factory executed with excellent precision in angle and brightness. However, the texture of the silver-gray sub-dials, in my opinion, is not as refined as the genuine product, though this difference is invisible to the naked eye and can be better understood through a comparison under natural light.

Other aspects like the hour markers and luminescence are also well-crafted. It’s worth noting that genuine 4131 models have transitioned to cylindrical pointer tips, but the four genuine pieces provided by Clean revealed some inconsistencies, such as variations in the hour markers’ roundness and the use of older conical pointer tips, suggesting Rolex might be clearing out 4130 inventory.

The case and bracelet have also been compared through photos, showing minimal differences in overall appearance.

Despite the tight timeline, Clean Factory purchased five genuine models immediately, experiencing a depreciation exceeding $100,000, not including dismantled or damaged parts. After thoroughly examining and photographing both the genuine and replica items, I believe this has been a remarkable creative effort.

Choosing the SH4131 involves a complex relationship, but it’s important to understand that SH does not equate to low quality. Likewise, Clean Factory never compromises on sourcing costs to increase profits. I was informed that the cost of procuring the SH4131 movement is not lower than that of the DD4130.

Due to lighting conditions, natural light real-shot images will be provided, which I believe should be considered as the standard for comparison.
