Hey bro: there're two kind of Daytona you can get from all list trusted dealer. They are just the same. However, both version of Daytona are not close with Gen & have different flaw. That's depend on how you choose: 1.) Daytona with A7750@6sec. The most famous problematic movement in rep world. 11 extra gears add on the movement in order to transfer the running sec from@9 to 6. The @6sec hand is shutter & the movement are very unstable; low power reserve & may die on any moment. Also, deal to the extra gear; the movement become very thick in 15mm. 2.) new Daytona in A23j, the thickness is same as Gen. But with no Chronos function. JF version suffering from too deep rehaust & Noob version suffering from chrono button are too long. As a result, there're not good Daytona up to this moment. I suggest you should take a look on other nice rep & enjoy them before a real good Daytona born. Some rumor said Clone 4130 movement is under development, MAYBE will come out in 2018. Let's wait & see whether it's true or not. Hope this could help!
