I never doubt the quality of Daytonas made by Clean factory, the bezel and dial details are better than other factories even they use the same Dandong 4130 movement. But how about the new Daytona from them? They are also much better than the ones made by ZF and AR+. Compared with ZF, Clean makes correct case shape and dial details, compared with AR+, the Shanghai 4131 movement is much better than the Dandong 4131 which AR+ uses. If you read my another post about the AR+ Daytona, you will know the real movement inside.
In the new Daytona, Clean uses Shanghai 4131 movement inside, it looks like that movement has a better decoration than the Dandong 4130, but its stability still needs time to be tested, after all, Dandong 4130 has been tested to be very stable for years. I heard a rumor that Clean is going to use Shanghai 4130 in their old Daytona models such as 116500, that will be bad if they abandon Dandong 4130. By the way, the ice blue Daytona with see-through crystal back is not available, many clients like this Daytona, but I think it will be available soon.
