Short answer
Cartier does not use 33672 as a Ballon Bleu reference number. Cartier references look like W69012Z4, W69011Z4, or W6920071. The 33672 code shows up on replica listings, dealer stock sheets, and marketplace SKUs. Treat it as a seller code. Ask which case size and which movement the 33672 code maps to before you send money.
Factory specs for the steel Ballon Bleu
- 28 mm: quartz, ref W69007Z4
- 33 mm: quartz, ref W6920071
- 36 mm: automatic, ref W69011Z4
- 42 mm: automatic, ref W69012Z4, caliber 049
The 42 mm case measures 42 mm across and about 13 mm thick. Cartier rates water resistance at 30 m. The crown sits inside a fluted guard and holds a blue synthetic spinel cabochon. The dial uses a guilloche finish, Roman numerals, and blued sword hands. Caliber 049 comes from an ETA 2892-A2 base and runs about 42 hours on a full wind. Cartier released the Ballon Bleu line in 2007.
Cartier Ballon Bleu 33mm and "33672" Replica Codes: What Buyers Should Know
Replica versions: where they differ
Replica Ballon Bleu watches change from batch to batch. Common specs on listings: 316L steel case, mineral glass or sapphire, Japanese quartz or a Chinese automatic. Thickness runs 1 mm to 3 mm over the 13 mm of the 42 mm genuine. Cabochon color ranges from pale cyan to deep cobalt. Caseback engraving depth and font weight vary. Bracelet end links fit loose on lower grades, and the clasp stamp is shallow.
Checks before buying
- Measure the case with calipers. Photos hide 2 mm.
- Weigh the watch. A steel 42 mm Ballon Bleu with a full bracelet comes in near 120 g.
- Ask for the movement name. A claim of Swiss movement with no caliber tells you nothing.
- Check the cabochon. It should sit centered in the crown.
- Skip water tests. Replica seals get no pressure testing.
Price ranges
Replica listings for the 33672 code run $80 to $400. Used steel 42 mm Ballon Bleu watches sell for about $4,000 to $6,000 on the secondary market. A 33672 listing priced near the genuine range is a mismatch. Cartier publishes no 33672 model, so no factory spec sheet exists for it.
