Is the Audemars Piguet Royal Oak 37mm (Ref. 15550ST) worth it?

WatchMerit currently rates the Ref. 15550ST a Hold. Mid-size RO with in-house 5900 calibre.

Any offer between $64,080 and $79,920 is considered a fair price — that's a ±11% band around the median. Below that range is under-market; above it is overpriced.

Full-set examples (box, papers, unpolished) sit near the middle of that range. Watch out for missing papers or heavy polishing — expect a 5–15% discount from median in those cases. International grey-market listings can look cheaper but almost always add GST, import duty and freight once landed.

Every live listing on WatchMerit is auto-labelled Under Market, Fair Price or Overpriced against this band, so you never have to guess.

Mid-size RO with in-house 5900 calibre. Collector demand is currently High — Fills gap between 34mm & 41mm.

Buying new from an authorised dealer typically involves a wait of about 6 years (Royal Oak 37 tight allocation, mostly long clients). For most buyers, the secondary market is the realistic route.

Historical secondary-market prices for the Ref. 15550ST have declined approximately 27.3% from the earliest tracked year to today, indexed from public market data, auction results and Australian dealer trade sheets.
