VSF Omega Watches: Seamaster, Aqua Terra and Planet Ocean Review

Written by Ray LI — a replica watch dealer with over 10 years of hands-on experience, sourcing directly from Chinese factories since 2015 and serving collectors across the US, UK, and Europe since 2023.

I’ve been selling VSF Omega watches since VS Factory first started producing them, and I’ve watched them go from a newcomer in the Omega replica space to the only factory I actually recommend. Back then, multiple factories were fighting over the Seamaster 300M market — MKS, ZF, OR Factory, and a few others. VSF won that fight, and it wasn’t close.

Out of every 10 Omega orders I process, about 5 are Seamaster 300M, 3 are Aqua Terra 150M, and 2 are Planet Ocean 600M. That ratio has been pretty consistent for the past couple of years. In this review, I’ll go through each series, cover the movements and build quality, and address the common question about VSF vs Clean Factory for Omega.

VSF Omega Seamaster: The Most Popular VSF Model

The Seamaster 300M is the most popular VSF Omega by a wide margin. Half of all my Omega sales go to this model. The black dial version outsells every other color, though blue and white have their fans too.

VSF prices the Seamaster 300M between $400 and $480 depending on the specific reference and configuration. That puts it in a similar range to other VSF sport watches and well below what you’d pay for a VSF Rolex Submariner.

I want to share some history here, because it matters. When VSF entered the Omega market, they weren’t the only option. OR Factory, MKS Factory, and ZF Factory all had their own versions of the Seamaster Diver 300M. I used to sell OR Factory Omega watches too. Stopped doing that. The after-sales rate was way too high — customers kept coming back with movement issues, and I got tired of dealing with returns. VSF’s Seamaster 300M had an after-sales rate around 1%. That gap is not something I can ignore as a dealer.

The reason VSF won the Seamaster war comes down to one thing: the Dandong 8800 clone movement. It’s a proper one-piece movement (especially the V4 upgrade), not a decorated ETA movement with a fake plate on top. Other factories were using modified 2824 or Seagull movements and slapping cosmetic plates over them. VSF built theirs from scratch to replicate the genuine Cal. 8800 structure. The date adjustment works through the hour hand — pull the crown to the first position, rotate the hour hand two full turns to advance the date by one day, and you can reverse it too. No other factory can do this.

The current V4 version uses the Dandong 8806 one-piece movement, upgraded from the previous shell movement (V3). Key improvements include a fully skeletonized rotor design, correct date adjustment direction (downward, matching genuine), and power reserve around 50+ hours versus the V3’s 40 hours. The ceramic bezel uses enamel-filled numerals that won’t fade or discolor — I’ve sold hundreds of these and never had a customer report bezel color issues.

Aqua Terra 150M is the second most popular, making up about 30% of my Omega orders. VSF prices these between $380 and $420. The Aqua Terra comes in both 38mm and 41mm sizes. The 38mm fits wrists under 16.5cm nicely and works well for dress occasions where the watch sits under a shirt cuff. The 41mm uses the Dandong 8900 movement with a dual mainspring barrel, while the 38mm uses the 8800 series with a single barrel.

VSF recently added some interesting color options to the Aqua Terra line — a Tiffany blue rubber strap version and a gray-black gradient dial in 38mm. The variety is much wider than the Seamaster 300M, which is partly why the AT captures 30% of orders despite being less well-known.

One thing to note: the Aqua Terra and Planet Ocean lines have almost zero demand for women’s watches. The market just isn’t there. If someone asks me about a women’s Omega replica, I’d steer them toward the Constellation or De Ville instead.

Planet Ocean 600M takes the remaining 20% of orders. These run $450 to $550 — the highest in the Omega lineup because of the larger case and more complex build. The standard size is 42mm+, though VSF recently released a 39.5mm version for smaller wrists. The Planet Ocean has been upgraded to V4 with a one-piece movement as well, up from the previous modified movement.

The 39.5mm Planet Ocean is actually a smart pick if you want a dive watch without the bulk. VSF is currently the only factory offering a one-piece movement in this smaller size. The ceramic bezel rotates smoothly with a crisp click, and the lume is dual-color — green on the minute hand and lume pip, ice blue on everything else.

Model	Price Range	Movement	Sizes	Order Share
Seamaster 300M	$400–$480	Dandong 8800/8806	42mm	50%
Aqua Terra 150M	$380–$420	Dandong 8800/8900	38mm / 41mm	30%
Planet Ocean 600M	$450–$550	Dandong 8900	39.5mm / 42mm+	20%

VSF Omega Watch: Movement and Build Quality

The movement is the reason VSF dominates the Omega replica market. Every VSF Omega uses a Dandong-made clone movement, and there are several versions depending on the model:

Dandong 8800 / 8806 — Used in the Seamaster 300M and some 38mm Aqua Terra models. The V4 upgrade brought a true one-piece construction. Power reserve sits around 50+ hours. Lifespan based on my customer feedback data: 4 years minimum, with many still running fine beyond that. The 8806 is the no-date version used in models like the Seamaster 300M “No Time to Die” edition.

Dandong 8500 — Used in the Aqua Terra 150M and De Ville series. This is actually one of the oldest VSF clone movements, with five or six years of proven track record. Almost zero returns. It’s the same movement used across multiple Omega lines, and it’s been refined over many production cycles.

Dandong 8900 — Used in the Planet Ocean 600M and Constellation 41mm. Features a dual mainspring barrel with real functioning gears — you can see them moving when you wind the crown. Power reserve reaches about 60 hours.

All of these movements share one key feature: you adjust the date by rotating the hour hand independently. Pull the crown to the first position, and only the hour hand moves. Two full rotations advance the date by one day. You can adjust forward and backward. This is exactly how the genuine Omega co-axial movements work, and no other replica factory has replicated this function.

There’s one known difference between the VSF movement and genuine: the regulator system. Genuine Omega movements use a free-sprung balance (no regulator pins — just one post with adjustment weights). VSF movements have a regulated balance with two pins (a regulator). If someone opens the caseback and knows what to look for, this is the one tell. For daily wear, it makes zero functional difference. Some owners have tried removing the regulator pins, but that makes the watch extremely inaccurate — don’t do it.

The build quality outside the movement is solid. The Seamaster 300M uses a ceramic bezel with wave-pattern ceramic dial. The dial texture, the applied Omega logo, the lume plots — all done properly. The lume is dual-color on the 300M (green for minute hand and pip, ice blue for everything else), which matches the genuine configuration.

I’ve personally tested VSF Omega watches for water resistance. The Seamaster and Planet Ocean are dive watches with screw-down crowns — I’ve had customers swim with them without issues. The Aqua Terra doesn’t have a screw-down crown, so I’d keep it to daily splash resistance. Don’t take it in the pool.

One honest note about the Seamaster 300M: there’s a known issue where the crown tube can become loose over time, affecting the screw-down seal. It’s not common, but it happens. If your crown doesn’t screw down tightly anymore, the whole tube assembly needs replacing — you can’t just tighten it. This is the kind of thing a good dealer should QC before shipping.

The sapphire crystal on VSF Omega watches has a slight dome shape with anti-reflective blue coating, matching the genuine. Case dimensions are consistently within 0.2-0.5mm of genuine specifications across all three lines. Weight is close to genuine steel models — the difference is negligible on steel versions since there’s no precious metal involved.

VSF vs Clean Factory: Omega Comparison

This section will be short because the answer is simple: Clean Factory has never made Omega watches. Not the Seamaster, not the Aqua Terra, not the Planet Ocean. Nothing. Clean Factory focuses entirely on Rolex — Submariner, Daytona, Datejust, GMT-Master II. That’s their lane.

So if you see someone comparing “Clean vs VSF Omega” online, they’re either confused or talking about Rolex and mixing up the brands. For a general Clean vs VSF comparison on Rolex models, I covered that in a separate article.

For Omega replicas specifically, VSF has no real competition right now. OR Factory re-entered the Seamaster 300M market recently with a Shanghai-made 8806 one-piece movement, and their exterior finishing on some details is decent. But I sold OR Factory Omega watches years ago and the return rate killed it for me. I stopped recommending OR to my customers entirely. Maybe their new version is better — time will tell — but I’m not gambling my customers’ money on it when VSF has years of proven reliability.

For Omega replicas, VSF is your only serious option. There’s no factory-vs-factory debate to have here.

FAQ

Is VSF the best factory for Omega replicas?

Yes. VSF is the only factory producing Omega replicas with proper clone movements that replicate the genuine co-axial functions — independent hour hand adjustment, bidirectional date correction, and correct crown positions. Other factories use modified generic movements that don’t match how a real Omega works. My after-sales data backs this up: about 1% return rate on VSF Omega watches across all models. That’s the lowest of any factory I’ve worked with.

Which VSF Omega model is most accurate?

The Seamaster Diver 300M, specifically the black dial version. It’s been in production the longest, gone through the most revisions (now at V4), and has the tightest tolerances. The ceramic bezel, wave dial, and case dimensions are all within fractions of a millimeter from genuine. The V4 movement upgrade to the Dandong 8806 one-piece brought it even closer to the real thing. Black dial also has zero color-matching issues — you can’t get a color wrong when it’s black.
