Speaking of the “king of rolls” among replica bezels, VS Factory definitely ranks high. Especially their Omega Seamaster 300 series, from V1 to V3, each generation upgrade can cause a wave of discussion. The V4 version has just been released recently, and many watch friends are asking: Is it worth it to switch to the Dandong 8800 integrated movement this time? After I got the actual product, I wore it seriously for a week. Today I will talk about my real feelings.

Appearance: classic elements + polished details, you can check the version at a glance
With a watch diameter of 42 mm, this size is actually quite “universal”. It won’t look obtrusive if you have a thin wrist, and it can hold up even if you have a thick wrist. The watch case is made of 316L fine steel, and the polishing process is really impeccable. The transition between brushing and polishing is very clean, and it feels smooth to the touch without any burrs.

The dial is the soul of this watch. The wavy pattern on the black ceramic plate is not the “fake three-dimensional” printed on a flat surface, but a real layered relief effect. When the light sweeps over, the light and dark changes of the ripples are natural and do not appear rigid. The calendar window at 6 o’clock is accurately positioned, the font is clear, and there is no ink spillage or skew.

The hands and scales are rhodium-plated and equipped with Super-LumiNova luminous coating. It has a silvery white texture during the day, and the luminous effect is also very powerful at night. The brightness is long-lasting and there is no problem at all when reading. This is very practical for friends who often go out at night or like to dive.
Bezel and mirror: taking into account both functionality and appearance
The ceramic bezel has always been the iconic design of the Haima 300. The black ceramic ring used by VS Factory this time, the scale is filled with white enamel, which has good wear resistance and will not fade easily in daily use. The ratchet-type one-way rotation structure has moderate damping when rotating, not too loose or too tight. The “click-click” sound is very crisp and the hand feedback is in place.

The watch mirror is dome-shaped sapphire glass, coated with anti-reflective film. This design is very practical, it won’t be dazzling when you look at the time under strong light, and it has high hardness, so it won’t easily leave scratches due to daily bumps. I have been wearing it for a week and the dial is still as transparent as new, which is a plus.
Movement upgrade: Dandong 8800 integrated movement, this time it is really “matched”
Speaking of the biggest change in the V4 version, it must be the movement. The old model used the modified plywood movement of Seagull 2824. Although the stability is good, the calendar adjustment direction is opposite to the original version, and the position of the balance wheel is also wrong. It always feels a bit “almost”.

This time, the replacement of Dandong 8800 integrated movement really solved the pain point. First of all, the calendar adjustment direction is finally consistent with the original version. The calendar is adjusted counterclockwise. This detail is too important for obsessive-compulsive players. Secondly, the power reserve has been increased from 40 hours to 54 hours, which is close to the original 55 hours. If you don’t wear it on weekends and take it out on Monday, it will still keep accurate time. You don’t need to wind it frequently, which saves you a lot of worry.

More importantly, the structure of this movement has been replicated 1:1. The diameter is 26.5mm and the thickness is 4.65mm, which is exactly the same as the original version. The position of the balance wheel has also accurately reproduced the left-shift design. Looking through the back, you can no longer see the flaw of the old model’s “centered balance wheel”. The surface of the movement is also carefully polished, with clear texture and smooth gear engagement. The measured travel time error is about ±5 seconds per day. This accuracy is considered excellent among replica watches at the same price.
Wearing experience: comfortable fit, one watch and two wearables
After actually wearing it, I am quite satisfied with the comfort. The curvature design of the watch case is very reasonable and fits the curve of the wrist without pinching or sliding. The watch strap is made of high-quality rubber material, which is soft and skin-friendly, and will not cause sweating when worn in summer. The folding clasp opens and closes smoothly, the engraving on the inside is neat, and the wearing firmness is no problem.

In addition, the VS factory still thoughtfully provides original factory-style tape and replacement rubber straps to achieve “one watch, two wears”. The steel strap is suitable for formal occasions, and the rubber strap can easily cope with casual sports scenes, making it highly practical.



Objectively talk about what needs attention
Of course, we have to tell the truth. Although the V4 version has obvious upgrades, it is still a replica watch after all, and there is definitely a gap between it and the original. For example, the scale filling of the ceramic ring is wear-resistant, but it may still be slightly worn after long-term high-intensity use. In addition, although the movement is stable, it is recommended to avoid frequent operation of the timing function in daily use to extend the service life.

Summary: Is the V4 version worth buying?
After a week of actual testing, my conclusion is: If you have struggled with the movement of the old Haima 300 before, the V4 version is definitely worth considering. The upgrade of Dandong 8800 integrated movement has brought this watch to a higher level in terms of functionality and restoration.
The appearance details are well controlled, the wearing comfort is high, and the movement stability is excellent. These advantages make the V4 version very competitive among replica watches at the same price. Although the price may be slightly higher than the old model, the premium is reasonable considering the cost of the movement and the upgrade of the craftsmanship.



Of course, you still have to be rational when buying a replica watch. If you are pursuing ultimate restoration and high cost performance, then the VS Factory Haima 300 V4 version is indeed a good choice. But if you have enough budget, it will definitely be better if you can buy genuine products. When it comes to playing with watches, having fun is the most important thing. Finding the one that suits your needs and budget is the serious thing.
By the way, before buying, it is recommended to find reliable channels, confirm the version and quality inspection, and avoid pitfalls. I hope this review can help you. If you have any questions, please feel free to chat in the comment area. See you in the next issue!
