Now many factories have released their Daytona 126500. The popular versions on the market are clean factory, QF factory, BT factory, VS (SB) factory. These are the famous factories producing replica watches, and each factory claims that their product is the best version, I think the QF version will be phased out first because it uses the 4130 movement (4130 with 4131 Caliber Decorations). The original version uses the 4131 movement.

Clean factories are very good at producing Daytona. The appearance details of the watches are usually the best in the market. With the Dandong 4130 movement, the Daytona of the clean factory has been the best version in the market for a long time. The new Daytona uses the Shanghai 4131 movement, not the Dandong 4131 movement. This time, the clean factory does not seem to have reached a cooperation with the Dandong movement factory.

The picture above is the Shanghai 4131 movement, BT factory uses Dandong 4131 movement, so many people now think that BT version is the best, and it is cheaper than clean version, The picture below is the BT factory Dandong 4131 movement

VS factory released two movements, one is the Dandong 4131 movement like the BT factory, and the other is the skeletonized 4130 movement. The skeletonized 4130 movement version is used to replace the 7750 movement in the market. This version is relatively cheap.

Personal opinion: For white dials, choose BT factory, which looks almost the same as clean factory, but the BT movement is better. For black dials, choose clean factory, which looks closer to the original.
