Hello everyone, I am keen on popularizing watch knowledge, comparing true and false, disassembling and evaluating, and being your navigator on the road of playing with watches, helping you not to get lost in playing with watches. Let's talk about the Daytona 116520 launched by Factory C, that is, the white steel Daytona and the black steel Daytona. Let's take a look at them first. The workmanship of these two models is also the ceiling level at present. Since the closure of Factory N, many watch friends have been looking forward to someone taking over the Dandong 4130 movement, because this movement has a very high stability, and it is also praised by everyone as the ceiling in the replica movement. In this chronograph movement, this movement can be compared with the Swiss ETA7750 movement. The stability is really very high, which is not exaggerated at all.

Let's take a look at its workmanship details. Let's make a simple comparison with the Panda Di. The biggest difference between the white steel Di and the Panda Di is the bezel. The Panda Di is a ceramic bezel, while the white steel Di is a steel bezel. The scale is directly on the steel bezel. The lettering is also slightly different. The Panda Di has three small black circles, while the white steel Di has a silver CD pattern, and a little golden yellow. So the lettering is very accurate, and the color is more positive than the Panda Di.

The nails on the dial are really amazing, and the polishing of each nail is really good. Including the polishing of the side and the polishing of the arc, including its brightness, there is also a process of platinum plating on it, so it will be very bright when you look at it in the sun from any angle. The pointer of Buff has no burrs and is polished very well. It also has a kind of stick-shaped feeling, which makes the three-dimensional sense quite good. Then this pointer is slightly sunken than the one made by the Panda Di, so there is no need to change the needle, the dial, the mirror, etc. The mirror is also made the same as the original one. It is slightly convex compared to the bottom of the Panda. This is also for the plate. The original white steel Di is also slightly convex. Then the edge is also polished with this arc. This edge is not cut off with a knife, but also has a little arc polishing.

There are no flaws on the front, including the scale on the bezel. You can see that the scale on the bezel is very thick and deep. It is better than the previous N factory, including some other messy factories we won’t talk about. The process is better than those. The color is also very positive. Including its crown, the protruding length is the same. The night light is also made to match the board, including its font printing, which is also this kind of oil pressure printing, the three-dimensional sense is still very good, and the center axis is also solid. The center axis is really made to match the board.

Then the strap is the same as before, the strap is from AR factory, and all the chamfers are polished, let's take a look at the details of the craftsmanship. Then the frosted lettering here is very deep, the same here, and the 7CD code. There are two points here. Cake feel. Including the sound. Quite good. It is also the highest level strap at present. The inside is also very clean. Then let's take a look at the black steel Di. Except for the different colors inside, everything else is the same, so for these two color combinations, it depends on which color you like personally, and the craftsmanship is also the same. The CD pattern is also brighter. And its pointer is very positive in all aspects.

Finally, I will tell you how to distinguish the difference between the 4130 and 7750 movements. Let's see how to operate it. When you wind the spring, just rotate the crown upward. That is, pull out the first gear when winding. It has no neutral gear. You can adjust the time in the first gear. Turn the crown upward. This goes clockwise. This is the 4130 movement. There are many 7750 movements in the market that can also be made in the first gear and as thin as before, but its winding direction is definitely different. This is also a simple trick to distinguish whether it is a 4130 movement without opening the cover. I hope Tao's article can help you. If you are interested, you may wish to pay more attention to this site. More detailed disassembly, real shot evaluation, and true and false comparison will be updated later. If you are rational enough and don't love to listen to sweet talk,
