Seiko
Seiko's upgraded automatic caliber offering a substantial 70-hour power reserve, nearly double the 4R35 it replaces in higher-end Presage and Prospex models. The extended reserve is achieved through a longer mainspring while maintaining the same 21,600 vph beat rate. Accuracy is tightened to -15/+25 seconds per day compared to the 4R35's wider tolerance. Represents Seiko's push to compete with Swiss movements offering 80-hour reserves.

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
FreeWhether 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
FreeHow 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
FreeHow often it changes hands, and how many are for sale now.
2 listed on the secondary market
16 sales closed in the last 90 days.
40 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.

The community take
Owners talk.
Seiko Prospex Land owners widely praise its comfortable, sub-12mm cushion case that wears smaller than its dimensions suggest, and its sharp, attractive appearance featuring outstanding brushing and applied indices. Reviewers note its legible dial, solid movement, and 100m water resistance at a fair price, with some owners appreciating its unique combination of features. However, the stock strap is consistently described as stiff and uncomfortable, and one owner would prefer a numbered bezel over cardinal directions. Accuracy is reported around -10 seconds per day, and the internal rotating bezel's action is considered good for the price but not as refined as higher-end models. On balance, owners and reviewers rate the Seiko Prospex Land highly for its comfortable wearability and attractive finishing at its price point.
