KEY SPECS

Display1.47" Super AMOLED, sapphire crystal, 3,000 nitsReadable in full sun, and the sapphire face shrugs off keys and door frames.
ChipSnapdragon Wear Elite (3 nm)The new Wear OS flagship chip — the reason this year's coaching runs on the watch, not in the cloud.
HealthBioActive sensor: Heart Health Score, sleep Vitals, blood pressureOne heart score instead of six charts — plus blood-pressure checks after a one-time cuff calibration, a trick no Apple Watch does.
Case40mm Armor Aluminum 2, IP68 + 5ATM, MIL-STD-810HShower, pool and rain are non-events, and the aluminum case stays light enough to sleep in.
Storage32GBApps, watch faces and offline playlists without rationing space.

WHY THIS PICK

Amazon and Target tie at $379.99 today — a genuine tie, checked today. The button goes to Amazon; if Target returns are easier for you, the price is the same and that is a fine reason.

Walmart does not sell this watch directly. The cheaper listings there are international marketplace models — we checked, and we print that absence as the result instead of borrowing a marketplace price.

Sleep Vitals, a personal Heart Health Score and running coaching, all running on the new Snapdragon Wear Elite — a generation ahead of the Watch 8 below.

HONEST NOTE

There is no discount to chase on this watch today — both stores sit at the full $379.99, and the Walmart "deals" are international models, not US stock. The real money decision is Bluetooth vs LTE: +$50 for the LTE model, then about $240 of plan over two years. If your phone is always with you, Bluetooth is the same watch for $290 less over two years.

THE CELLULAR MATH (checked Oct 29, 2026 — plan prices are the common carrier add-on rate; your carrier's page is final)

Bluetooth model — $379.99, no plan needed. Two-year total: $379.99.

LTE model (40mm) — $429.99 (+$50). Watch plan about $10/mo × 24 months = about $240. Two-year total: about $669.99.

The verdict: LTE costs about $290 more over two years. It earns that only if the watch regularly leaves the phone behind. Otherwise the Bluetooth model is the same watch, the same coaching, $290 cheaper to own.

THE TRADE-OFF

Last generation's chip and coaching — the Watch 9's Heart Health Score and faster on-watch AI help are what the extra $104.99 buys.

WHY SMARTBUYCOMPARE

Same product. Three stores. Three different prices. Here, two stores tie at $379.99 — and the third does not sell it directly at all.

The +α pick does the same job for $104.99 less: last year's Watch 8 — still coached, still tracking, still blood-pressure capable.

The compared pick is the lowest checked price we can stand behind — today, that is the Amazon–Target tie at $379.99, and the button goes to Amazon.
