The new C Factory 126509 Cement Grey model has arrived, with variants equipped with the 4131 movement rolling out gradually. We will post C Factory’s new releases on our website as soon as they launch. This model is not built for value seekers and suits buyers who are less price-sensitive.

If you prioritize cost-performance, I recommend entry-level versions from BT Factory or VS Factory. The build quality across these factories is largely comparable, so do not over-rely on marketing descriptions. Below is the factory breakdown:

The hour markers and lume are well executed. The tube tips of the hands have been redesigned to cylindrical shapes. However, after examining four genuine reference watches obtained by Clean, we spotted several flaws. For instance, the roundness of hour markers is inconsistent, and some hands still retain the older conical tube tips. This suggests Rolex may be clearing stock of the 4130 movement. Side-by-side photos of the case and bracelet are included; visually, the overall differences are minimal.

Despite the tight timeline, Clean purchased five genuine examples right away. Reportedly, depreciation on these watches has exceeded 100,000 US dollars, excluding fully disassembled timepieces and damaged components. I have inspected both genuine and replica pieces in person and photographed them for comparison. In my opinion, this is a remarkable development.

There is a complicated backstory behind the selection of the SH4131 movement. Please understand that SH does not equate to low quality. Clean also states it never cuts procurement costs for higher profit margins. According to Clean, the purchasing cost for this SH4131 movement is no cheaper than that of the DD4130.

Discrepancies may arise due to lighting conditions. Natural-light live photos will be attached, and I suggest referencing these real-shot images for evaluation.
