The fastest way to tell a fake Ballon Bleu 31610 is to look at the crown and its guard before anything else. On a genuine watch the fluted crown nests inside a curved shoulder that flows out of the case, and the blue cabochon is a domed, translucent stone set into the crown head. Replicas show themselves here first: a flat or milky cabochon, a guard with a hard step instead of a smooth sweep, or a crown that sits proud of the case. Every check below is judged against four criteria that matter on this model: how the part is made (machined and set versus cast and glued), how it reads under a 10x loupe, how it behaves in the hand (winding, setting, weight), and whether the engraving, polishing, and dial print are consistent with each other. One good detail and one bad detail on the same watch means the watch is bad.
How to Identify High-Quality Ballon Bleu 31610 Clone Watches
Crown and Cabochon
The crown assembly is the highest-yield check on this model because it is the hardest part to copy at cost.
- Genuine: cabochon is domed, shows depth and slight color shift from royal blue to near-black at the edges, and is set flush with the crown rim.
- Genuine: crown fluting is cut, not stamped, and the teeth stay sharp under a loupe.
- Genuine: the crown guard curves out of the case band with no visible seam or tooling mark.
- Fake: cabochon looks like flat plastic or dyed glass, often purple or gray-blue, and sits above the rim.
- Fake: guard has a stepped shoulder or a gap where it meets the case, and the crown wobbles when you pull it.
Use this check first when you are looking at photos only, since the crown is visible in almost every listing image. Ask for a straight-on macro shot and a side profile shot.

Dial, Printing, and Secret Signature
The dial is where cheap replicas lose the argument under magnification.

- Genuine: the flinqué texture is cut into the dial, so the rings catch light and change as the watch moves.
- Genuine: the word Cartier is crisp, with even stroke weight and clean serifs, and Roman numerals are applied, not printed.
- Genuine: hands are blued steel, faceted along the length, and reach the minute track exactly.
- Fake: guilloché pattern is printed or stamped shallow, so it looks flat in every angle of the photo.
- Fake: printing looks fuzzy at 10x, numeral edges are soft, and hands are painted blue over steel.
Ask the seller for a loupe photo of the numerals and of the small Cartier signature worked into one of the hour markers. If the seller cannot produce a sharp macro image, treat that as an answer.
Case Shape and Lugs
The case is a balloon: convex, thick through the middle, and tapering into lugs that curve down toward the wrist.
- Genuine: caseback is domed, the case band has a continuous polish with no ripples, and lugs are slim with a soft radius at the tip.
- Genuine: the watch sits with weight in the palm and feels dense for its size.
- Fake: slab-sided case with a flat back, thick lugs, and polishing that shows waves in reflected light.
- Fake: light in the hand, and the spring bar holes sit off center.
This is the check to lean on when you handle a watch in person at a shop or a private meeting, because weight and reflected light are hard to fake in photos.
Caseback Engraving and the 31610 Reference
Reference and serial stamping is where counterfeiters get sloppy, because the numbers have to be cut, not cast.
- Genuine: engraving is cut deep with clean edges, the reference and serial fonts match, and the numbers sit level with the caseback ring.
- Genuine: caseback screws are flush, all slots point the same way, and the threads are clean.
- Fake: laser-etched or cast numbers with rounded edges, uneven spacing, and a font that does not match the reference you were shown.
- Fake: mismatched numbers between the caseback and the paperwork, which is the single most common failure on replica listings.
Always ask for a photo of the caseback and a photo of the papers in the same message. Compare the digits, not just the general look.
Crown Action and Movement
Winding and setting tell you more than any cosmetic detail, and they cannot be faked in a photo.
- Genuine: crown turns with light, even resistance, the stem has no side play, and the date or time change is clean.
- Genuine: the seconds hand sweeps smoothly, and the rotor is quiet when the watch is tilted.
- Fake: gritty or loose winding, a stem that clicks when nudged, and a seconds hand that ticks or stutters.
- Fake: noisy rotor, and a date that changes late or hangs halfway.
Use this check on any in-person deal before money changes hands. Wind it 20 turns, set the time forward past midnight, and listen.
Bracelet, Clasp, and Screws
The bracelet is a finishing test: alternating brushed and polished surfaces are expensive to do well.
- Genuine: links are held by screws with clean heads, the clasp closes with a solid click, and the folding parts line up flush.
- Genuine: brushing runs one direction, and the polished bevels are sharp, not rounded over.
- Fake: pins instead of screws, screw heads that strip, a clasp that rattles, and brushing that runs in two directions on the same link.
Check the bracelet last, after the crown, dial, caseback, and movement, because a good bracelet on a bad case is the classic replica trap.
