C Factory New Model 4131 — Natural Light Comparison

Model 126500 in black. This listing highlights key points of visual comparison—especially the three silver sub-dials on the dial, the most significant update in the 4131 movement. Clean’s execution excels here: the bright beveled rim surrounding each sub-dial is precisely rendered in terms of angle and luminosity. However, the silver-gray sub-dials themselves exhibit slightly less refined guilloché texture compared to the genuine article—though this difference is imperceptible to the naked eye and best observed under natural light (see accompanying side-by-side natural-light photos).

Other details—including applied hour markers and lume application—are also exceptionally well executed. Note: Rolex officially updated the 4131’s hands to feature cylindrical pivot tips (replacing the older conical ones). Yet among the five authentic reference watches Clean acquired for benchmarking, we observed inconsistencies—such as varying degrees of marker rounding and, notably, some hands still using the legacy conical pivot tip. This suggests Rolex may be clearing remaining 4130 inventory.

Case and bracelet comparisons (shown in photos) reveal negligible aesthetic differences from the original.

Despite extremely tight timelines, Clean promptly procured five genuine examples for reference. Reportedly, the market value depreciation of these authentic pieces has already exceeded USD 100,000—excluding disassembled units and damaged components.

Having meticulously examined both genuine and replica specimens in person—and corroborated observations via high-resolution photography—I consider this 4131 replica a truly outstanding achievement.

The choice of SH4131 involves nuanced considerations. Please understand: ‘SH’ does not equate to compromised quality; nor does Clean ever sacrifice material standards to maximize profit. Clean confirmed that the procurement cost for the SH4131 movement is on par with that of the DD4130.
