What a Nautilus 5712/1A Clears for in Bangkok — June 2026
The Nautilus 5712/1A combines moon phase, power reserve indicator, pointer date, and sub-seconds. Introduced in 2006 alongside the Nautilus 30th anniversary, Patek discontinued the reference in 2022.
Thai Watch Market logged 6 transactions Jan–May 2026 — meaningfully lower supply than the 5711:
- Low ฿5,800,000 — 2016–2018 references or half-sets
- Median ฿6,450,000 — Full-set 2019–2021 with verifiable AD warranty
- High ฿7,200,000 — NOS 2022 (final year) with factory stickers
5712 vs 5711 in Bangkok
| Feature | Nautilus 5711/1A | Nautilus 5712/1A |
|---|---|---|
| Complications | Time + date | Moon phase + power reserve + date + sub-seconds |
| Dial layout | Clean | Four sub-features |
| Caliber | 26-330 S C | 240 PS IRM C LU |
| Year discontinued | 2021 | 2022 |
| Median Bangkok 2026 | ฿8,150,000 | ฿6,450,000 |
| Thai supply | Moderate | Low |
Despite more complications, the 5712 trades below the 5711 because:
- 5711 is the "iconic Nautilus" — Genta's original 1976 silhouette
- Wider buyer base for 5711 — the clean dial appeals more broadly
- 5712 layout perceived as "busy" — some collectors prefer the 5711 simplicity
- 5711 discontinuation premium started earlier — 2021 vs 5712's 2022
What Bangkok Dealers Pay
| Scenario | Seller payout (2020 full-set) |
|---|---|
| Full-set, TH warranty | ฿5,890,000–฿6,225,000 |
| Full-set, overseas warranty | ฿5,580,000–฿5,890,000 |
| No box, papers | ฿5,225,000–฿5,540,000 |
| Loose | ฿4,838,000–฿5,148,000 |
Dealers pay 87–91% — slightly below 5711 because resale velocity is slower.
Caliber 240 PS IRM C LU — Why Collectors Value It
Patek's caliber 240 is a micro-rotor movement just 3.98mm thick, allowing the 5712 to stay 8.52mm overall despite more complications than the 5711.
Authentication points Khun Naru examines:
- Micro-rotor 22k gold — must carry Geneva Seal stamping and hand-polished finish
- Moon phase aperture — moon is 3D polished on authentic examples; fakes are flat
- Power reserve hand — sweep must be smooth and consistent
- Sub-seconds at 5 — indices hand-polished
