The short answer: a fake Cartier Tank 2370 v4 is worth considering only when it clears five checkpoints, and those checkpoints are case profile and thickness, dial printing and layout, hand shape and finish, crown cabochon, and movement with caseback engraving. Everything else in a listing is noise. The \"v4\" suffix is a seller convention, not a Cartier designation, so the label itself proves nothing. What follows is a criterion-by-criterion way to judge one of these watches before you spend money, plus the tradeoffs that come with the category.
What the 2370 v4 label actually means
Cartier reference numbers of the 2300 and 2370 family are tied to the Tank Francaise era, and sellers in the replica market borrow those numbers loosely. A listing quoting 2370 may describe a steel Tank with an integrated bracelet, a leather-strap Tank, or a case size that does not match the original reference at all. The v4 tag is a factory batch marker. It signals that a maker has revised a model several times, usually in response to complaints about an earlier run.
Fake Cartier Tank 2370 V9: The Ultimate Guide
Pros of buying by version code
- Later batches tend to fix visible flaws from earlier runs, so a v4 often beats a v1 on case shape or dial print.
- Version numbers give you something concrete to compare across listings and photos.
Cons of buying by version code
- No central registry exists. Two sellers can offer different watches under the same v4 label.
- A high version number can be pure marketing rather than evidence of a real revision.
Best for: buyers who will compare actual photos against the criteria below instead of trusting the number alone.
Checkpoint one: case profile, dimensions, and finish
The Tank case lives or dies on its proportions. Look for a flat caseback, a crisp step where the brushed band meets the polished bezel, and lugs that curve down toward the wrist rather than jutting out.
Pros seen on better batches
- Correct brushed and polished transitions on the brancards.
- Caseback screws or a snap fit that sits flush with no gap at the edges.
Cons to watch for
- Added thickness, often half a millimeter to a full millimeter over the original, which changes how the watch sits under a cuff.
- Soft or rounded case edges from a worn polishing mold.
Best for: anyone who wears the watch with a shirt cuff, where thickness is the first thing people notice.
Checkpoint two: dial printing and layout
The Roman numerals, the rail track, and the hidden signature inside the VII are the three places a cheap dial reveals itself. Print should be thin and even, with sharp terminals on the numerals and no ink bleed into the surrounding lacquer.
Pros seen on better batches
- Correct spacing between the numeral ring and the minute track.
- A secret signature that blends into the numeral stroke instead of standing out.
Cons to watch for
- Heavy or glossy print that reads as paint rather than ink.
- Guilloche-style texturing that is stamped too deep or fades near the edges.
Best for: buyers who will photograph the dial close up, since print quality is the easiest flaw to capture.
Checkpoint three: hands, crown, and cabochon
Sword hands should be faceted, with a clean center ridge and a blue finish that shifts under light rather than sitting flat. The crown should seat into the case without a visible gap, and the cabochon should be a smooth dome with a deep blue tone.
Pros seen on better batches
- Hands with a genuine facet rather than a stamped flat blade.
- A cabochon set straight, with no glue residue at the base.
Cons to watch for
- Cabochons that are too tall, too pale, or off-center.
- Crowns that wobble when you set the time.
Best for: buyers who handle the watch before wearing it, because the crown and cabochon are the two parts you touch and see at arm's length.
Checkpoint four: movement and caseback engraving
Movement choice drives the feel on the wrist. A quartz Tank should tick once per second with a crisp, quiet step. A mechanical version should wind without grit and run with a steady sweep.
Pros seen on better batches
- Quiet operation and a crown that engages immediately when pulled.
- Caseback text with even depth and consistent font weight.
Cons to watch for
- Loud rotors on automatic versions and a hollow sound when tapped.
- Mismatched or duplicated serial numbers across the caseback and paperwork.
Best for: buyers who plan to wear the watch daily rather than keep it in a box, since movement reliability matters more than cosmetics over time.
Checkpoint five: bracelet or strap, clasp, and fit
On a bracelet model, check that links articulate without rattle, that the clasp closes with a firm click, and that the end links meet the case without a step. On a strap model, check that the leather is not stiff cardboard and that the pin buckle is signed.
Pros seen on better batches
- Solid links with even brushing and a clasp that sits flat when closed.
- Buckle engraving with the same font weight as the caseback.
Cons to watch for
- Hollow links that pinch hair and stretch over months.
- Straps with sealed edges that split after a few weeks of wear.
Best for: buyers who want to size the watch at home, since a bracelet with removable links is far easier to fit than a fixed one.
The risks that no version number removes
These watches are unlicensed copies of a trademarked design. In the United States, trafficking in counterfeit goods is a federal offense, and shipments can be seized by customs. There is no manufacturer warranty, no service network, and no resale market of any depth. Water resistance claims on replica listings should be treated as unverified. A watch that looks correct in photos can still arrive with a misaligned dial or a movement that fails within a month.
Verdict
Judge a fake Cartier Tank 2370 v4 on the five checkpoints above and ignore the version number as a quality signal. The strongest candidate is the one whose case thickness, dial print, hand facets, cabochon, and caseback engraving all survive a close photo review, sold by a seller who will show real images of the actual unit. Buyers who need a warranty, water resistance they can trust, or any hope of resale should skip this category entirely and put the money toward an entry-level watch from a brand that stands behind its product.
