What a Ballon Bleu WSBB0039 Clears for in Bangkok — June 2026
Cartier Ballon Bleu launched in 2007 — a rounded case with the signature integrated crown beneath a domed sapphire guard. WSBB0039 is the 40mm steel version using caliber 1847 MC, the Cartier in-house automatic.
Thai Watch Market drawn from our work in Bangkok's pre-owned market Jan–May 2026:
- Low ฿155,000 — 2019–2020 references, worn, no box
- Median ฿185,000 — Full-set 2022–2023 with TH warranty
- High ฿225,000 — NOS 2024 with stickers
Ballon Bleu Silhouette — What the Thai Market Values
The Ballon Bleu has a "rounded but not perfectly circular" case shape with the crown integrated inside the case profile, protected by a domed sapphire guard. Cartier patented the design in 2007.
What Bangkok collectors weigh:
- Integrated crown — crown sits inside the case, creating a silhouette no other reference replicates
- Sapphire cabochon under glass guard — visible blue sapphire that can be rotated from outside
- Roman numerals — Cartier roman pattern shared across Tank, Santos, Ballon Bleu
Ballon Bleu Size Variants
| Size | Reference | Median Bangkok 2026 |
|---|---|---|
| 40mm steel | WSBB0039 | ฿185,000 |
| 36mm steel | W6920071 (quartz) | ฿138,000 |
| 33mm steel | WSBB0048 | ฿125,000 |
| 42mm rose gold | WGBB0009 | ฿485,000 |
40mm is most traded in Thailand because it works across male and female wearers — Cartier designed Ballon Bleu as a genuinely gender-neutral piece.
What Bangkok Dealers Pay

Dealers pay 80–84% — similar to Santos and Tank Louis.
WSBB0039 Authenticity Checkpoints
- Crown integration — crown must sit flush with case profile; fakes commonly protrude
- Sapphire cabochon — blue sapphire beneath glass guard, Cartier-specific
- Caliber 1847 MC — visible through sapphire caseback, Côtes de Genève finishing
- Roman numerals applique — markers polished 360 degrees
- Glass guard dome — must be sapphire dome; fakes use thinner mineral glass
Caliber 1847 MC
Cartier's in-house automatic introduced in 2010 — uses paramagnetic alloys for anti-magnetic resistance, 42-hour reserve, 28,800 vph. Significant because it predates Cartier's full in-house transition, when Cartier still relied on ETA and Jaeger-LeCoultre within the Richemont group.
