Year-by-year readings →

Four signals, read separately

Supply, attention, intent and resale, each read from its own evidence and reported with its own sample. They are never added together: a watch that is hard to buy and a watch that is badly wanted are different facts, and one blended number cannot tell you which you are looking at.

Scarcity

Free

Whether the brand still sells it, and every change we have seen.

Reading…

Read from the brand's own product pages and stock feeds, not from shops or resale listings. We can only show changes we saw, so a quiet history is not proof that nothing moved.

Attention

Free

How many people here are keeping track of it.

Reading…

Favourites, collections and wishlists from signed-in members, counted as distinct people. Views are excluded on purpose: per-watch view counts were found to anti-correlate with real traffic and there is no bot filter at the write path. Gross adds only, because an un-save deletes its row, so a fall here is less new interest and not people walking away.

Intent

Market+

Taps through to somewhere it can actually be bought.

Part of Market+

Outbound taps are the one axis we assemble ourselves rather than read off somebody else's storefront, and they are part of Market+.

One row per redirect we issued to somewhere this watch can be bought, written on the server after the destination was checked, with crawlers excluded. A tap is intent and never a purchase: no sale or commission can be derived from it. The log carries no exposure count, so there is no click-through rate here and no ranking of watches by taps.

Liquidity

Free

How often it changes hands, and how many are for sale now.

None listed right now, but it does trade

3 further sales with no date, counted apart because they belong to no window.

Public enthusiast forum listings matched to this reference automatically, counted alongside dealer storefronts and never blended with them. Counts only on this panel. What one is worth is the market act's own question, and its figures carry their own sample sizes.

A silent axis is shown rather than hidden, so the ones with something to say cannot be mistaken for the whole picture.
