The Shanghai 4131 movement is an impressive collaboration between Shanghai and Clean, crafted to perfection. This advanced movement features a 75-hour power reserve and is meticulously polished, electroplated, engraved, and assembled by Clean, ensuring a high level of precision and quality.

Prevailing issues with the previous Shanghai 4130 movement, such as stability concerns, timing inaccuracies, poor finish, incorrect dimensions, winding feel, and rotor noise, have been expertly resolved in the Shanghai 4131. This movement now stands as a testament to progress in replica watchmaking.

In direct comparison to the genuine 4131, the Shanghai 4131 reveals an identical appearance and size, with only minor differences in shock absorbers. Clean’s exclusive handling of the Shanghai 4131 movement guarantees a replication that closely matches the original’s quality.

The pieces released for internal testing have received positive feedback, though the Shanghai 4131 awaits further market validation. As Clean continues to refine the production process, customers can anticipate an even closer resemblance to the genuine article with future releases.

Overall, the Shanghai 4131 movement showcases exceptional attention to detail, offering high fidelity to the original while enhancing reliability and performance. This innovative movement sets a new standard in the realm of replica watch movements, promising to surprise and delight enthusiasts.
