VS Factory Omega Seamaster 8800 movement's best Collectwatch

In Omega’s huge product matrix, the Seamaster series has always been one of the brand’s most recognizable classic families. The 39.5mm Seamaster watch equipped with the 8800 integrated movement, with its just right size, exquisite ceramic bezel technology and stable and reliable movement performance, has become the perfect choice for countless watch fans "suitable for daily commuting and diving sports". The Top Collectversion launched by VS Factory this time is based on this popular work, completely replicating its appearance aesthetics and mechanical core. This article will give you an in-depth analysis of the craftsmanship features and wearing experience of this VS factory 39.5mm Seamaster watch from multiple dimensions.
1. Authentic traceability: 39.5mm - the golden size in the Haima series
Omega's Seamaster series has a rich product line, covering a wide range of watch diameters from 37mm to 45mm. Among them, the 39.5mm version is a very special existence - it is more refined than the 42mm Haima 300m, and more sporty than the 37mm Haima Aqua Terra. This size is extremely friendly to Asian wrists: it not only retains the tough temperament that a diving watch should have, but also does not "stress the wrist" like a large watch diameter, and can be easily controlled by both men and women.
The genuine product is equipped with the Omega 8800 coaxial escapement self-winding movement. Launched in 2016, this movement is a compact version of the 8500 movement. Its main features include:
coaxial escapement——Reduce friction and extend maintenance intervals
silicon hairspring——Antimagnetic performance up to 15,000 Gauss
55 hours power reserve——Take it off on the weekend and wear it again on Monday and still keep accurate time
Certified by the Ultimate Observatory——Daily error 0 to +5 seconds
The watch is equipped with a stainless steel case and bracelet, a ceramic one-way rotating bezel, and an anti-reflective sapphire glass mirror. It is a truly professional diving watch with a waterproof depth of 300 meters. It is these core selling points that have become the key elements that VS Factory needs to overcome when re-engraving them.
2. Movement breakthrough: VS factory 8800 integrated movement, bid farewell to the plywood era
The success or failure of a diving watch, the restoration of the movement is the key. The biggest technical highlight of the top Collectwatch VS Factory Haima 39.5mm is that it is equipped with the independently developed 8800 integrated automatic movement, which completely bids farewell to the "fake integrated" solution of the traditional version using Citizen or Seagull movements with cover plates.

The core features of the VS Factory 8800 movement include:
true one-piece structure——The design, layout and parts structure of the movement are highly consistent with the genuine 8800, rather than the "two-layer skin" of ordinary movement + decorative plywood
Black balance wheel——Restore the appearance of the black balance wheel of the genuine 8800, which is an important visual feature that distinguishes high and low versions.
Coaxial escapement simulation——Although it is impossible to realize the true physical structure of the coaxial escapement in the Collectmovement, the VS factory has visually restored it to a high degree. The position of the balance wheel and the appearance of the hairspring are very close to the original.
Jump calendar mechanism synchronization——The feel of fast and slow calendar adjustment is consistent with the original product, and the steps of each gear are clear when pulling out the crown.
In terms of stability, the VS Factory 8800 movement has been verified by the market in many batches, the travel time accuracy is controlled within a reasonable range, and the repair rate is lower than similar products. For watch lovers who pursue the viewing angle of the back and the restoration of the movement, the integrated solution of the VS factory is undoubtedly the best solution on the market.
It is worth reminding that VS Factory also has a 42mm version of the Haima 300m, which is equipped with the VS Factory 8500 integrated movement. The 39.5mm version uses the 8800 movement. The two have similar structures but different sizes. Do not confuse them when purchasing.
3. Case and size: 39.5mm - Good news for Asian wrists
The best Collectwatch vs factory hippocampus case size is one of the most attractive selling points of this watch. The 39.5mm watch diameter falls into the “small size” category among diving watches, but the effect is surprisingly good.

The following is a reference for the wearing effect of different wrist sizes:
| Wrist circumference | How it looks when worn | Recommendation |
|---|---|---|
| Below 15cm | It may be slightly larger, but the lug placement is moderate | ⭐⭐⭐ |
| 15-17cm | Perfect fit, this is the golden adaptation zone | ⭐⭐⭐⭐⭐ |
| 17-19cm | The visual effect is more sporty but still coordinated. | ⭐⭐⭐⭐ |
| 19cm or more | It’s a bit small, so it’s recommended to consider the 42mm version. | ⭐⭐ |
The case is made of 316L fine steel, and the surface is fully brushed - this is a classic approach for diving watches. The brushed surface can effectively cover up minor scratches in daily use. The curvature and length of the lugs have been optimized to naturally fit the curve of the wrist when worn, without the common problem of "warped lugs".
Regarding the crown, VS Factory has restored the iconic screw-in crown of the Haima series, with anti-slip tooth patterns and a clear operating feel. The screw-in structure and waterproof ring ensure the structural foundation of 300 meters waterproof performance.
4. Ceramic bezel: one-way rotation, diving timing core
The most core functional part of a diving watch is the chronograph bezel. The bezel of the Haima series is made of ceramic, which has extremely high scratch resistance and fade resistance, and remains as bright as new after long-term use.
VS Factory has invested a lot of effort in replicating the ceramic bezel:
material (that sth is made of)——Using the same grade of zirconia ceramics as genuine products, with high hardness and warm texture
tick fill——The first 15 minutes of the scale are filled with enamel or similar technology. The white is bright and will not fall off or turn yellow.
One-way rotational damping——The sense of paragraphing and damping when the bezel rotates has been carefully adjusted, and every "click" sound is clear and crisp, without any looseness.
luminous spot——The triangular luminous dot at 12 o'clock is fully filled, and the luminous brightness is close to that of the original product.
The design logic of the one-way rotation is very simple: before diving, the diver aligns the "0" scale of the bezel with the minute hand, so that the elapsed time can be read at any time underwater. Since the bezel can only rotate counterclockwise, even if it is accidentally touched, it will only display "longer diving time" to ensure safety. VS Factory faithfully reproduces this functional logic and is by no means a decorative bezel.
5. Disk and watch mirror: anti-reflective sapphire, as transparent as nothing
The dial is where the wearer’s gaze stays for the longest time, and VS Factory also spared no effort in restoring the dial craftsmanship.
The background color of the disk is classic black or white (depending on the version), and it adopts lacquer technology to ensure a uniform and full color without any graininess. The hour markers adopt a three-dimensional inlaid design, and the metal frame contrasts sharply with the luminous filling. The hands are the iconic hollow broad sword needles of the Seamaster series, with sharp shapes and finely polished surfaces.
Luminous light is the lifeline of a diving watch - under water or in dark light environments, the ability to read clearly is a matter of safety. The VS factory uses Super-LumiNova material for the luminous filling. The luminous spots on the hour markers, hands and bezel appear blue-green in dark light, and the brightness durability is close to that of genuine products.
The watch mirror is sapphire glass with high transparency and double-sided anti-reflective coating. The value of this coating technology is that in strong light environments (such as the sea under the scorching sun), ordinary glass will produce severe reflections, interfering with reading time; and anti-reflective coating can greatly reduce specular reflection, ensuring that the dial content is clearly readable under any light. VS Factory’s investment in this detail reflects its respect for the attribute of “professional diving”.
6. Watch strap and buckle: Stainless steel bracelet + folding buckle, double insurance for wearing safety
The strap is the only contact medium between the watch and the human body, and its comfort directly affects the long-term wearing experience. The VS factory 39.5mm hippocampus is equipped with a stainless steel strap, made of 316L material, and the links are assembled independently, avoiding the "overall stiffness" problem common in lower versions.
The strap is polished using a combination of polishing and drawing - the middle of the link is brushed and the edges are highly polished, with rich levels of light and shadow, consistent with the original. When worn, the strap can naturally fit the curve of the wrist without pinching hair on the hands (a concern of many stainless steel strap wearers) and leaving no obvious indentation on the wrist.
The buckle is another highlight of this watch from VS Factory. The stainless steel folding buckle of the Seamaster series is equipped with a diving extension device - this is a feature that many consumers tend to overlook but is actually very practical:
Regular wear——The folding buckle closes normally, suitable for daily wrist size
Dive extension——Press the button and the buckle can be extended by about 1-2 cm for wearing the watch outside a diving suit.
Fine-tuning function——There is a micro-adjustment hole in the buckle, which can be finely adjusted according to the thickness of the wrist.
VS Factory has achieved the same level of complexity as the original version in restoring this structure. The snapping feel and release confirmation of the extension device have been carefully adjusted, so that there will be no loosening or accidental unlocking.
7. Wearing experience: suitable for both men and women, suitable for commuting and diving
An excellent watch must ultimately be tested by the wearing experience. The ergonomic performance of the VS Factory 39.5mm Haima is remarkable.
The first is the size: the 39.5mm diameter is suitable for most Asian wrists. For men, this is a watch that is “neither too big nor too small”. It can easily slide into the cuff when wearing a formal suit, and will not look too weak when wearing a T-shirt. For women, 39.5mm belongs to the "large watch diameter" category, but the tough diving watch shape paired with a slender wrist presents a fashionable "contrast beauty". Many female consumers deliberately choose this size as a daily accessory.
Second is the weight: the weight of the stainless steel version is well controlled and will not "fall" like a large-diameter diving watch. The weight ratio of the case and strap is reasonable, the center of gravity is evenly distributed, and long-term wearing will not cause fatigue.
The third is functionality: the 300-meter waterproof rating means it can be safely worn for swimming, snorkeling, and even scuba diving (of course, it is not recommended to use Collectwatches in deep diving scenarios). Daily scenarios such as washing hands, getting wet in the rain, and swimming are no problem.
Summary: VS Factory 39.5mm Seamaster - golden size, integrated movement, synonymous with sincerity
The 39.5mm version of the VS Factory Omega Seamaster 8800 integrated movement is a deep tribute to the design language of classic diving watches. From the 8800 integrated movement independently developed by VS Factory, saying goodbye to the visual gap of the plywood era; to the 39.5mm gold size, which is comfortable and suitable for Asian wrists; from the precise damping of the ceramic one-way rotating bezel to the transparent experience of anti-reflective sapphire glass - every detail proves to the market: Excellent Collectworks require systematic restoration of materials, structures, and movements, rather than simple "appearance imitation."
The following table summarizes the differences between the core configuration of the VS factory 39.5mm Haima and the ordinary version on the market:
| Components | Features of VS Factory 8800 integrated movement version | Common shortcomings of ordinary versions on the market |
|---|---|---|
| movement | 8800 integrated movement, black balance wheel, jumping calendar and synchronous feel | Citizen/Seagull cover plate, white balance wheel, poor calendar feel |
| sizes | 39.5mm, golden size, suitable for both men and women | Size deviation, poor adaptability |
| bezels | Ceramic one-way rotation, enamel scale filling, precise damping | Aluminum alloy or ordinary ceramic, the scale is easy to fade and loosen |
| crystal | Sapphire + double-sided anti-reflective coating, ultra-high transparency | Ordinary sapphire or no coating, serious reflection |
| straps | Stainless steel five beads or three plates, combined with throwing and pulling | Low-standard steel, rough polished, uncomfortable to wear |
| clasp | Original folding clasp with built-in diving extension | Simple buckle, no extension function, poor buckling feel |
| waterproofing | 300 meters, screw-in structure | The virtual mark is waterproof and the structure is simple. |
For watch lovers who love the design aesthetics of Omega Seamaster and pursue gold size adaptability and stable movement performance, the VS Factory 39.5mm Seamaster is undoubtedly one of the most noteworthy choices. With its solid craftsmanship and sincere materials, this classic diving series radiates pure vitality in the field of Collect.
