ABOUT THE CROWN INDEX

An honest grade for every piece worth wanting

The Crown Index is a free luxury resale guide for Rolex, Hermès, Chanel, Omega, Cartier, Tudor and Breitling. Look up any watch reference or bag and get boutique retail against what it really sells for, recent sold prices, its price history and a plain-English grade you can act on. Most market sites are spreadsheets wearing websites. We built the opposite.

How the grades work

Every piece gets a score out of 100, built from five meters. The score maps to the letter grade mechanically, so nothing gets a pass for its name. Some references and bags do earn an F: a crown on the dial or an H on the clasp does not repeal math.

Letters carry a plus or minus by thirds of each band: A- is 80 to 83, A is 84 to 86, A+ is 87 to 89, and the same split applies to B, C and D.

S90+Trophy piece
A80 to 89Strong buy-and-hold
B70 to 79Solid, selective
C58 to 69Wear it, don't flip it
D45 to 57Buy it to use
FBelow 45The market has spoken
MomentumPrice direction. The median sale of the last 4 months against the median of 8 to 12 months ago, plus the 3-year trend for watches. Thin samples are pulled toward zero.
LiquidityHow many sell each year and how fast current listings sell.
ScarcityWhat it sells for against boutique retail, with a lift for discontinued models. Rarer vintage pieces score on how seldom they trade.
Value entryWhere today's price sits against its own history. Buying a dip scores higher than buying a peak.
Condition and authenticityFor watches: age of the design and how steady its prices are. For bags: how often it is faked.

Watches: measured, and graded together

For Rolex, Omega, Cartier, Tudor and Breitling, every meter is computed from three years of recorded eBay sales. There are no hand-set numbers. All watch brands are graded in one run and ranked against each other, so a B means the same on a Rolex as on a Breitling. Vintage pieces are ranked against vintage, modern against modern.

Two rules sit on top. An S needs a market price at or above boutique retail, and an A needs one within 10% of it. A piece with no verified retail on record can reach neither.

Bags

Chanel meters are computed from recorded sales, except authenticity, which is our judgment of how often each bag is faked. Hermès meters are editorial judgments on defined rubrics, informed by sales data and market history. They are opinions, held honestly and updated regularly.

Where the numbers come from

Real sold pricesCompleted eBay sales over the last 12 months via Terapeak (eBay's sold-data tool), shown on each piece's page. With 8 or more sales, the market range is the middle half of them (25th to 75th percentile); with fewer, it is centered on their median and flagged as thin. 362 of our 419 pieces are priced from 3 or more recorded sales in the last 12 months. Rare vintage pieces that almost never sell on eBay keep an estimate from dealer and auction pricing, and their pages say so plainly.
Live listingsA daily pull of current eBay listings for every reference and bag, logged into our own price history.
Dealer pricingAuthenticated dealer, auction and resale-platform pricing, used only where there are too few recorded sales to set a range.
Boutique retailOfficial US prices, read from the brand's own site where it publishes them (every current Rolex is checked against rolex.com, every current Breitling against breitling.com) or from authorized dealers. Where a price could not be confirmed it is labeled as an estimate, and vintage pieces are compared with the new model sold today, labeled as such.

The 6-month outlook

Each price chart extends six months forward as a shaded range, not a single number, because nobody can predict a single number honestly. It leans with recent momentum, but that pull is capped and reverses for the hottest runs. Scarcity and a cheap entry price nudge it up; an expensive entry or a D or F grade nudges it down. The band widens when something is hard to sell, risky to buy or thinly documented.

Treat it as a reasoned estimate, not a promise.

What we are not

Not financial advisors, not appraisers, and not affiliated with Rolex, Tudor, Omega, Cartier, Breitling, Hermès or Chanel. Luxury watches and bags are a store of value at best and a passion at heart.

Buy what you love, verify everything, and treat any appreciation as the bonus, not the plan. Some outbound links are affiliate links; see our disclosure.
