The TW4131 Cosmic Daytona is officially here a truly exclusive version with the 4131 movement. The TW 4131 movement is directly developed based on the original 4131, featuring reasonable design and excellent stability. In contrast, the Shanghai 4131 movement is derived from the 4130 movement, which uses 7750 technology, resulting in inferior components like fake bridges and fake shock absorbers, leading to poor stability and difficult maintenance. Choosing the right version is crucial. Stay tuned for more comparative information. Highly recommended as the most stable version in every aspect at the moment!
