What a Royal Oak Offshore 26420 Clears for in Bangkok — June 2026
The 26420 launched in 2021, replacing the eight-year run of the 26470. The major change: caliber 4404 (in-house chronograph) replacing the 3126/3840 modular Frédéric Piguet base.

Méga Tapisserie Pattern
The Offshore uses "Méga Tapisserie" — a larger square pattern than the Royal Oak's Grande Tapisserie. The dial has more depth and a more industrial character.
Khun Naru's checkpoints:
- Méga Tapisserie depth — squares must be roughly 0.18mm deep, consistent throughout
- Sub-dial alignment — tri-compax layout must read cleanly
- Sub-dial finishing — azurage pattern distinct from the main Tapisserie
- Rubber crown and pushers — Hublot-style rubber must hold shape
Caliber 4404 — In-House Chronograph
The 4404 is AP's new in-house chronograph caliber: column wheel + vertical clutch + flyback. The transition from caliber 3126 (modular base from Frédéric Piguet) to a true in-house movement was AP's strategic vertical-integration play, matching Rolex and Patek.

Offshore 26420 vs Daytona 116500LN

|---|---|---|
| Size | 43mm | 40mm |

Offshore carries a much higher MSRP premium because AP Thai allocation runs lower than Rolex.
