What you actually get
The paragraph below is Amazon's own sales copy. We keep it quoted and set apart rather than folded into our text, because marketing prose and a description are not the same thing — and because what it leaves out is as useful as what it claims.

The price, read properly
Amazon publishes a single figure for this configuration — $439.99 — and no separate list price beside it. That removes the usual anchor, and it is the honest reason you will find no percentage anywhere on this page. The specification has to justify the money on its own.
The listing carries an end date of 28 September 2026. Retailers pull pages early and without warning, so read that as the outer edge rather than a promise.
What else the tracker has at this money
The closest tracked listings in wearables are Apple Watch Series 12 GPS 42mm Light Gold Aluminum Case with Sand Sport Band - M/L at $378.99 (Best Buy) and Google Fitbit Air Special Edition Stephen Curry - Rye at $129.99 (Amazon). Both undercut it, so the case for paying more has to come from the table below rather than from the price.
These are the nearest listings by price that our tracker currently holds, not a survey of the market. Anything not on sale at one of the six retailers we follow does not appear here at all.
The strongest reason to pick it is the heart and readiness data, which runs at a frequency you will not
