Short answer
V7 is the seventh revision of the replica Cartier Tank Must 2021, and it sits near the top of the current replica ladder for this model. Compared with V6, it fixes the dial print thickness, the cabochon shape, the depth of the caseback engraving and the fit of the quick-release strap. It is not a perfect copy. The tells that survive are the blued hands, the edge of the crystal and the finish inside the caseback.
What the real Tank Must 2021 is
Cartier relaunched the Tank Must in 2021 as the replacement for the Tank Solo. The Large measures 33.7 x 25.5 mm and the Small 29.5 x 22 mm, both at 6.6 mm thick in steel. It runs a quartz movement, uses sapphire crystal, carries 30 m of water resistance and hides the Cartier signature inside the numeral VII. The hands are blued steel swords, the crown carries a blue synthetic spinel cabochon, and the SolarBeat variant adds a photovoltaic movement with an eight-year battery claim. Get those baseline facts straight first, because every replica flaw shows up against them.

What changed between V6 and V7
- Dial print is thinner and closer to the gen weight. Earlier versions looked slightly chalky under a loupe.
- The cabochon is a better dome, with a color that reads navy rather than bright royal blue in daylight.
- Caseback engraving is deeper, so the reference text holds shadow instead of washing out.
- Strap spring bars and quick-release tabs line up better, which kills the loose rattle that plagued V6.
- Case edge bevel is softer, closer to the brushed-to-polished transition on the original.
None of that is dramatic on its own. Stacked together, it is the difference between a replica that reads as a watch on the wrist and one that reads as a replica.

How to read the dial
Start with the secret signature in the VII. On a good V7 it is faint and it needs a tilt of the light to show. On a weak one it is too deep, too wide, or placed off center. Next, look at the minute track. The lines should be crisp and evenly spaced, with no ink bleed at the corners. The rail print at 12 and 6 should sit tight to the chapter ring. I also check the Roman numerals for thick-to-thin stroke variation, since replicas tend to render them as a single uniform weight.
Fake Cartier Tank Must 2021 V6: What the Version Code Means
Case, caseback and screws
The Tank Must caseback is held by four screws, and this is where V7 separates from older stock. The slots should be clean and the heads flush. Screws that sit proud, or slots that look chewed, mean a lower grade. Run a finger over the engraving. Good depth feels like a step, not a scratch. Check that the reference and serial text is centered and that the caseback sits flat against the case with no visible gap at any corner.
Crown and cabochon
A blue spinel dome should catch light and show slight depth. Painted or resin cabochons on cheaper versions look flat and too saturated. The crown itself should turn without grit and should sit centered in the case flank. V7 crowns are decent. The failure point is the setting, where a cabochon that is glued rather than set can shift after a few months of wear.
Movement, weight and feel
The gen is quartz, so a replica does not need to fake a rotor wobble. What it does need is a quiet sweep. The seconds hand should tick once per second, not skip or stutter, and the crown should have a firm click between positions. On the wrist, a V7 with the stock strap lands close to the real weight. If it feels light and hollow, the case is likely a lower grade alloy.
Strap and hardware
Cartier ships the Tank Must on calfskin with quick-release spring bars. The replica strap is the weakest part of the package on most versions, V7 included. Check the stitching density, the taper and the pin buckle finish. A swap to a decent aftermarket strap does more for the look than any other upgrade.
What still gives it away
- Hands that read blue paint rather than heat-blued steel under strong light.
- Crystal edges that are too thick or show a visible halo at an angle.
- Inside caseback finish that is rough or shows tool marks.
- Dial print that is slightly too heavy at arm's length.
Buying checklist
- Ask for macro photos of the dial, caseback and crown at an angle.
- Confirm the version label in writing, not just in a listing title.
- Check the secret signature in the VII before anything else.
- Verify screw heads and engraving depth on the caseback.
- Ask about the strap and whether quick-release bars are included.
- Test the seconds hand and crown action on arrival, then check water resistance assumptions stay conservative.
Treat V7 as a good replica, not a gen. Buy it for the shape and the dial, budget for a strap, and keep your expectations on the hands and crystal.
