Speaking of the “entry classic” of Rolex Daytona, Panda Di (white plate with black circle) is absolutely inescapable. The black and white contrasting color + three-eye layout is low-key and a bit professional. It can be used in commuting, sports, and business situations. No wonder it has become the “universal model” of many watch friends.
However, the original price is more than 100,000 yuan, and the price in the secondary market has to be increased, so many friends who like Panda Di can only look at the “bear” and sigh. Fortunately, the replica market gives us a “replacement” option. The VS factory has indeed made some progress in the field of Daytona replicas in recent years, especially the new Panda Di equipped with the Dandong 4131 movement.

But here’s the problem: there are too many Daytona factories on the market, including APS, BTC, Clean, QF… the versions are confusing and it’s hard to tell the true from the false. Today purewatches will put aside those false parameters and teach you step by step how to identify the authenticity VS Panda Di, so as to avoid spending money on “Li Gui”.
1. Differences between old and new models: 3 details that can be distinguished at a glance
Panda Di is divided into new and old models, with three key differences in appearance:
1. Ceramic ring with metal edging:
- New style: The edge of the ceramic ring has metal edging, which makes the texture more refined;
- Old style: There is no metal edge on the edge of the ceramic ring, and the ceramic is directly exposed.



2. “SWISS MADE” mark at 6 o’clock:
- New style: There is a small crown logo in the middle of SWISS and MADE;
- Old style: no crown logo, just SWISS MADE.

3. Back cover opening size + thickness:
- New model: The back cover has a larger opening and a thickness of 12.1mm;
- Old model: The back cover has a slightly smaller opening and a thickness of 12.4mm.
⚠️ Little reminder: Thickness is an important indicator to identify the VS factory. Use a caliper to measure it. 12.1mm is the new model and 12.4mm is the old model. If it is not the original model, it will be excluded directly.
2. Ceramic ring: gray matte coating is the key
As for the ring mouth, VS Factory did a solid job this time. There are two key points in the identification:

Coating color:
- Must be gray, not white or glossy;
- The gray matte coating is a platinum filling process, which is waterproof and oil-proof and will not fade.
Coating texture:
- It must be matte (matte texture), not glossy;
- Many small factories will use white glossy coating to fool them, which can be distinguished at a glance.
The ceramic material itself has high hardness, so you don’t have to worry about scratches when wearing it daily. The scale fonts are clear and the edges are sharply cut. It will not fade or turn yellow after long-term wear.
3. Disk function: Don’t open the timing pointer randomly
The disk adopts the classic Panda Di three-eye layout:
- 9 o’clock: Chronograph hour dial;
- 6 o’clock: Chronograph minute dial + small second hand;
- 3 o’clock: No calendar (Daytona no calendar design).
There is a key detail: the large chronograph seconds hand at 12 o’clock only moves when the chronograph function is turned on, and is always fixed at 12 o’clock. Many novices will misunderstand this point and think that the watch is broken, but it is actually a normal design.

⚠️ Usage suggestions: The timing function can be turned on whenever you use it. Do not turn it on for a long time. Turning on the timer for a long time will accelerate gear wear and greatly shorten the power reserve (70 hours may become more than 30 hours). It is recommended to only turn it on when needed for daily wear.
4. Scale pointer: rounded corners + solid center axis, big manufacturers’ skills will not fool you
scale time scale:
- The new model has longer and slender scales, while the old model is shorter and fatter;
- All corners are rounded, not rigid right angles, and feel delicate to the touch.
pointer craftsmanship:
- The edge of the pointer is polished smoothly, and you can’t find any burrs when you zoom in;
- The central axis adopts a solid stamen design, which is consistent with the original structure, and there are no obvious flaws in macro observation;
- The first batch of VS factory even provides a magnifying glass to let you see the precision of the pointer and the central axis, which many small manufacturers cannot do.
Disk printing:
- The fonts are clear and sharp, with sharp edges and no blur;
- The ink is full and not weak, and you can’t find any faults even when viewed from a close distance.

5. Material and process: 904 steel + secondary polishing, quality online
The case, strap, and buckle are all made of 904L fine steel, which is corrosion-resistant and wear-resistant, and will not easily turn black and oxidize after long-term wear. This is much more reliable than the 316L steel used by many small factories.
Shell polishing:
- All corners have been polished once and twice, making it comfortable to wear without cutting your hands after removing the film;
- The brushed texture is uniform, the polished part is bright and transparent, and the transition between the two processes is natural.

clasp details:
- The crown logo is integrally formed and inlaid, with no welding points underneath, which many small factories are lazy about;
- The inside of the buckle is made of frosted steel, with no welding points, and the edges are polished smooth and will not scratch your hands;
- The opening and closing of the safety buckle has moderate damping, and there will be no loose and stuck feeling.
6. Movement core: Dandong 4131, 5 details to identify authenticity at a glance
The movement is the ultimate key to identifying VS factory Panda Di.
The Dandong 4131 integrated movement (new model)/4130 (old model) equipped has 5 key identification points:


1. Automatic rotor hollow design:
- The Dandong 4131 automatic rotor is a hollow design, not solid;
- The hollow part is finely polished and the edges are burr-free.
2. Lettering font:
- The crown logo and font should be fine and slender, not particularly thick or “fat”;
- Many imitations will make the fonts rough and confusing, so that they can be distinguished at a glance.
3. Number of bearings:
- Dandong 4131 uses 27 ceramic ball bearings;
- If the number of balls is insufficient or the material is wrong, it can basically be judged to be a low-end version.
4. Shock absorber type:
- It must be Powerflex shock absorber, which is standard equipment of Dandong 4131;
- Other shock absorber versions can basically be ruled out.
5. Balance wheel color:
- Golden balance wheel + counterweight, consistent with the original structural principle;
- A silver balance wheel or weightless design can basically determine that it is not a Dandong movement.

7. Real advantages and disadvantages, don’t brag or discredit them
Advantages:
- The identification details of new and old models are clear and pitfalls are guaranteed to be avoided.
- The ceramic ring has a gray matte coating, which is durable and does not fade.
- Pointer rounded corners + solid center axis, big manufacturers’ skills are not fooled
- 904 steel + secondary polishing, texture and comfortable to wear online
- Dandong 4131 movement, 27-axis bearings + Powerflex shock absorber, stable and durable
- VS factory quality control is stable, and the overall restoration level ranks first in the replica circle.
Disadvantages:
- The market versions are confusing, so you need to identify them carefully before buying.
- The price may be slightly higher than other factories
- Replica watches are replicas after all, and you need to accept them psychologically
- The timing function should not be turned on for a long time, please pay attention to your usage habits
8. Buying Suggestions: Who is suitable to buy?
If you like the classic design of Panda Dee, but feel that the premium of the original version is too high, then this model from VS Factory is indeed worth considering. It is not the kind of low-end product that is fake at first glance. It will not look shy for daily wear or gatherings with friends.

Especially the combination of Dandong 4131 movement + 904 steel + gray matte coating is currently the best choice among replica Daytonas. Although there is still a slight gap from the original version, considering the appearance, movement, and wearing experience, it does deserve the title of “cost-effective replacement”.
Purewatches’ suggestion is: find a reliable channel to get the product. When you get it, first check whether the thickness is 12.1mm (new model), whether the ceramic ring coating is gray pitted, and whether the automatic rotor of the movement is hollowed out + 27-axis bearings. If there is no problem with these three points, you can basically wear it with confidence.
Warm reminder: This article is only for communication and reference for watch enthusiasts, and supports genuine products and rational consumption. Buy a watch because you like it, don’t let “face” kidnap your wallet. Having fun wearing a watch is the most important thing.
