One of the most notable updates on the 4131 model is the three silver sub-dials on the dial. The significant enhancement lies in the addition of a shiny ring around the edges of the sub-dials, which has been executed cleanly with precise angles and brightness. However, in terms of the silver-gray sub-dials, the texture may not be as refined as the genuine product, though this is imperceptible to the naked eye. You can examine the details further under natural light for comparison.
Other aspects such as the indices and lume have been executed excellently as well. It's worth noting that although it's mentioned that the genuine 4131 model features cylindrical tube heads for the hands, upon examining four genuine pieces provided by Clean, some discrepancies were found. For instance, there were differences in the roundness of the indices, and some hands appeared to have the older tapered tube heads. This suggests that Rolex may still be clearing out inventory of the 4130 model.
In terms of the case and bracelet, there are minimal differences in overall appearance.
Despite the tight timeframe, Clean promptly acquired five genuine pieces. It's said that the value of the watches themselves has depreciated by over $100,000, excluding disassembled watches and damaged parts. I've carefully inspected both genuine and replica pieces and compared them through photography, and personally, I believe this to be an excellent creation.
The decision to choose the SH4131 involves complex considerations, but I hope everyone understands that SH does not equate to low-quality. Likewise, Clean never compromises on procurement costs to maximize profit. Clean informed me that the procurement cost of the SH4131 movement is not lower than that of the DD4130.
