What a Royal Oak Offshore 26420 Sells for in Bangkok — October 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.
Estimated price bands for the steel 26420SO as of October 2026. They start from WatchCharts market values (US$30,801 on 21 September 2026; US$31,346 for the .A600CA.01 on 7 October 2026; earlier range US$29,486–36,998), cross-checked against Luxury Bazaar's 2026 average of US$32,600. They are converted at ฿32.5/USD with no discount. They are estimates from US and international market data, not Bangkok transaction records:
- Low ฿960,000 — Steel 2021–2022, worn
- Median ฿1,010,000 — Steel full-set 2022–2023, TH warranty
- High ฿1,200,000 — Steel NOS 2024+ (rose gold and ceramic sit above this range; see below)
26420 Variants — Steel vs Rose Gold vs Ceramic
| Reference | Material | Median Bangkok 2026 |
|---|---|---|
| 26420SO (any dial) | Steel | ฿1,010,000 |
| 26420RO | Rose gold | ฿1,435,000 |
| 26420CE | Black ceramic | ฿1,555,000 |
Rose gold and ceramic sit well above steel: WatchCharts puts the 26420RO at US$44,163 and the 26420CE at US$47,861, against about US$31,000 for steel. We found no dial premium within the steel model. Earlier versions of this page labelled the steel model 26420ST with a .A027CA.01 suffix. WatchCharts, Chrono24 and dealers list it as 26420SO (for example .A002CA.01 black and .A600CA.01), and we found no 26420ST or .A027CA reference.
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.
What Bangkok Dealers Pay

| No box, papers | ฿754,000–฿800,000 |
| Loose | ฿697,000–฿743,000 |
Dealers pay 84–88% — similar to the 15500ST.
Offshore 26420 vs Daytona 116500LN
| Feature | AP Offshore 26420 | Rolex Daytona 116500LN |
|---|---|---|
| Size | 43mm | 40mm |
| Thickness | 14.4mm | 12.4mm |
| Material | Steel | Steel |
| Caliber | 4404 in-house | 4130 in-house |
| Used median | ฿1,010,000 | ฿890,000 |
| Market value vs retail | About 35% below US$47,300 US retail | Not re-checked in this update |
Used, the two are now close: the steel Offshore costs about ฿120,000 more. The "premium over MSRP" this table used to show for the Offshore was wrong: the steel 26420 trades well below its US retail price, not above it.
