Blue leads in Thailand — works across business and casual contexts, and is the colour AP markets most heavily.
Grande Tapisserie — What Collectors Examine
The Royal Oak dial features "Grande Tapisserie" — a small-square guilloché pattern proprietary to AP.
Khun Naru's authentication checkpoints:
- Tapisserie depth — squares must be deep with sharp lines
- Pattern alignment — symmetry with hour markers
- Sub-dial integration — date aperture at 3 must sit flush with the Tapisserie
"AUDEMARS PIGUET" Applique vs Printed
The 15500ST changed the dial signature from printed (15400ST) to applique gold — a 3D applique hand-polished. Fakes circulating in Bangkok 2024–2025 sometimes still use printed signatures — an immediate red flag.
