The server gathers marketplace asking prices for the confirmed reference, cached for 24 hours per reference. The phone never talks to any outside service directly. With no keys, the server runs on demo data and says so with a banner.

1. If you said the watch comes with its box and papers, only full-set listings count; if not, only listings without.
2. The prices are sorted and the median found.
3. Anything below 60% of the median is dropped as suspiciously cheap. That end of the market is where fakes, parts and franken-watches live.
4. The report gives the lowest remaining ask as the headline figure, then the average of up to 20 lowest remaining asks, the median, the number of comparable listings and how many were excluded.
5. At least three listings are needed. Prices are in pounds sterling.

It never gives one confident number. The lowest ask, the low-20 average, the median and the sample size sit together, so a thin market is plain to see. In the example above: 37 listings, a median of £3,250, a floor of £1,950, 4 excluded, a lowest ask of £2,450 and an average of £3,037 across the 20 lowest.
