It's been almost a year since the release of the new generation of Rolex Daytona caliber 4131. Earlier this month, Clean relaunched four models of Daytona with the Shanghai 4131 caliber after more than half a year of tireless efforts. This movement is well worth waiting for.
What are the differences between the genuine Rolex 4131 movement and the 4130 movement? Rolex 4131 automatic chronograph movement, on the basis of 4130 movement, upgraded Rolex Chronergy escapement. This is the "skeletonized escapement" used by Rolex on the 32 series movements. The number of ball bearings on the automatic tourbillon has also been increased. The old caliber 4130 had 7 ball bearings, the new caliber 4131 has 29 (I counted). In terms of movement performance, there are no changes, the 4131 still has 72 hours of power. In terms of movement polishing, the new 4131 caliber, in the upper plate, uses Geneva stripes decoration, while the old 4130 caliber is all radial brushed finish. One of the platinum case Daytona, with a transparent bottom, uses an all-gold automatic tourbillon; the other Daytona with a closed bottom uses a steel rotor piece.
Many watch lovers who pay attention to Daytona replica watches know that only before Clean's Daytona used the Danton 4130 movement. This movement has been verified in the market for several years, the quality is very stable, and the power reserve is also close to 65-70 hours. So how does the Shanghai movement replica caliber 4131 perform? We disassembled an original Rolex 4131 movement and Shanghai 4131 movement for this purpose to make a comparison, and see what are the differences between the two?
By comparing the pictures, the genuine 4131 and sh 4131 are almost identical in appearance and size. That is to say, the Shanghai 4131 movement structure is an exact replica of the original movement. However, SH 4131 has some differences, one is the shock absorber, the other is the balance wheel, SH 4131 balance wheel is not fitted with weights to adjust the speed, instead of a steel piece with a small screw.
The SH4131 caliber is an upgrade from the previous Shanghai 4130 caliber. The previous Shanghai 4130 caliber, judging from the return rate of sold Daytonas, was not stable enough compared to the Dandong 4130 caliber, and there were problems with individual chronograph functions that could not be recovered. Shanghai 4130 movement is difficult to compete with Dandong 4130 movement in terms of both size and feel of winding, as well as the noise of the automatic tourbillon piece. The Shanghai 4131 has obviously learned from the lessons of the previous 4130 caliber, with a 70-75 hour power reserve, retaining the advantage of energy storage, while leaving the polishing and assembly of the movement to the Clean factory. Strictly speaking, this new Daytona movement is a collaboration between Clean and the Shanghai Manufacture.
Every time Clean Factory releases a new product, if the movement is changed, the quality and stability of the product will be tested internally on a small scale, and only after passing the test will the new product be released, and finally the best product will be delivered to the buyers. In fact, I am not very enthusiastic about the new products of replica watch factories, because I know that these replica watch factories are all about making money. These watch factories don't make their watches perfect and then sell them because they want to win buyers' praises, they tend to upgrade the deficiencies of their watches while selling them. So some buyers have to pay again for better quality, just to get the same model of watch a little bit better.
