Some clarification. They use the Peacock 4801/4802, which is a legal copy if the 4130. There are minor differences in architecture such as rotor and other things but the 4801/4802 is basically a 4130 clone.
Sugess and Farasute and Cronusart are some brands that use this 4801.
You won't find any gen watches using the true DD4130 clone.
