Short answer
The replica Ballon Bleu 33674 lives or dies on four details: a 36 mm case that measures roughly 9.5 to 10 mm thick, a domed blue cabochon seated in the crown, a dial with actual guilloche texture rather than a flat print, and a smooth sweeping automatic movement. Verify those four and the watch reads right on a wrist. Miss one and a practiced eye catches it in seconds.
What the 33674 Copy Has to Match
Sellers list the mid-size stainless Ballon Bleu automatic under reference 33674. The genuine piece is a 36 mm round case in polished steel, with a fluted crown guard that curves into the caseband, Roman numerals on a textured dial, sword-shaped blued hands, and a date window at 3 o'clock. The crown guard is the signature move: the crown sits inside a metal arc, with the blue cabochon peeking out of the top. Copy makers who get the case right often botch the guard, and the reverse happens just as often.
Details that separate a good copy from a bad one
- Dial texture: fine concentric or grid guilloche that catches light, not a flat screen print.
- Cabochon: deep blue, smooth dome, no seam or glue ring where it meets the crown.
- Crystal: sapphire with an anti-reflective coating on the inside face, not mineral glass.
- Hands: blued steel tone, sharp sword tips, correct length that reaches the minute track.
- Bracelet: solid links with screws, tight articulation, no rattle when you shake it.
What to Have Ready
- A digital caliper or a steel ruler for case and lug measurements.
- A kitchen scale that reads in grams.
- A 10x loupe and a bright desk lamp.
- Maker catalog photos of the genuine reference on screen for side-by-side comparison.
How to Inspect One, Step by Step
- Measure the case diameter across the bezel from the 3 o'clock edge to the 9 o'clock edge. It should read 36 mm.
- Measure case thickness from the caseback to the top of the crystal. Anything past 10.5 mm sits too tall on the wrist.
- Turn the watch over and check that the caseback engraving is crisp, correctly spelled, and cut into the metal rather than printed on it.
- Look at the crown guard from the side. The arc should flow out of the caseband with no visible gap or solder line.
- Examine the cabochon with the loupe. Reject any stone with bubbles, a flat top, or a visible ring of adhesive.
- Tilt the dial under the lamp and confirm the guilloche pattern shifts and shadows as the angle changes.
- Check the date window edges and the numeral font against your catalog photo.
- Set the crystal under the lamp and look for a faint blue or purple reflection, which signals an anti-reflective coating.
- Weigh the watch on the scale. A steel 36 mm automatic on a full bracelet should land near 100 grams or above.
- Wind the crown about 30 turns and listen. A gritty grind means a rough keyless works.
- Set the watch down and watch the second hand for a full minute. It should glide, not tick once per second.
- Flip the watch and listen to the rotor spin. A light whir is normal; a scraping or rattling noise is not.
- Squeeze each bracelet link. Solid links hold their shape; folded links flex and creak.
Flaws That Justify a Return
- A quartz movement. Any tick per second disqualifies the watch at this price.
- A mineral crystal with scratches straight out of the box.
- Roman numerals that are painted on instead of applied or printed with clean edges.
- Cabochon color that leans purple or gray instead of a saturated blue.
- A crown that will not seat flush after winding.
Before You Order
