What we measure
The questions a finance professional would ask about any asset:
- Fair value for a specific model and condition
- What an owner actually nets after buying and selling costs, not just the price change
- Liquidity: how quickly a watch could realistically be sold
- Risk: how much prices swing and how far they have fallen from past peaks
- Market conditions: sentiment, supply, momentum and where the market sits in its cycle
Realized prices first
What watches actually sold for carries the most weight. Asking prices are informative but are adjusted before use, never taken at face value.
Like-for-like comparisons
Prices are compared on a consistent condition and configuration (dial, bracelet, box and papers). A shift in what happens to be listed is not reported as a change in value.
Clean inputs
The same watch listed in several places counts once. Relists are merged. Listings that look too good to be true are screened before they can influence a value or appear as a bargain.
Honest about uncertainty
Every figure comes with a range, a data-quality grade from A to E and plain-language flags such as "few recent sales" or "asking prices only". When the data is too thin, ObiFID says "insufficient data" rather than guessing.
Descriptive, not predictive
We measure the market as it is. We don't forecast prices, promise returns or tell anyone what to buy or sell.
Independent
ObiFID is analytics only: it doesn't buy, sell, broker or hold watches. Rankings and valuations can't be bought, and any referral links will be labeled and kept separate from results.
Reproducible
Every figure is timestamped and tied to the data and model version that produced it, so it can be checked and explained later.
The ObiFID Watch Index
A rules-based index of the secondary watch market, with a companion index showing returns after costs. The full rulebook will be published before the first release, and any later changes will be announced in advance.
