Japan holds 113 live Audemars Piguet Royal Oak Offshore listings across these 18 references — medians here are computed within Japan only, from sellers whose jurisdiction is Japan, not from prices shown to Japan visitors. Figures are INR-anchored, converted once at the timestamped rate above, and rounded — a median is an estimate and reads as one. A lower median in one market is not yet a like-for-like saving: duty, import taxes and each market’s tax treatment stack on top, and this page draws no conclusion it cannot substantiate — the landed-cost calculator does that arithmetic per destination, and the methodology page states how every median is produced. Reference-level detail lives on each reference’s own page, linked above, dated 2026-08-09.
