Rumored — not yet announced. Apple has not confirmed Apple Watch Series 12 or any specification on this page. Everything below is drawn from leaker and analyst reporting, cited to its original source in our news coverage. Last updated 2026-08-26; this page will be rebuilt with confirmed specs once Apple officially announces the device.
Apple Watch Series 12
Expected to announce September 2026 (expected — unconfirmed as of publication) · Expected release September 2026 (expected — unconfirmed as of publication)
What's rumored so far
Bloomberg's Mark Gurman reports Apple is in "late-stage testing" of the Series 12 in both Wi-Fi and cellular variants — a firmer signal than most pre-launch Watch leaks carry. The headline change is a new chip after a full generation stuck on the same silicon, plus a battery-life push. Gurman is explicit that several louder rumors — Touch ID, a blood-pressure sensor, microLED — are not happening this year. None of this is confirmed; Apple has not announced this device.
The Series 12's existence and September timing are unusually well-sourced (Gurman's "late-stage testing" language, not a typical early leak). Where this page is honest about weaker sourcing: the exact new chip name (S11 vs S12) isn't settled, and the battery-life target is a Weibo-sourced estimate, not a confirmed spec. We've also flagged, not silently omitted, the louder Touch ID/blood-pressure/microLED rumors that Gurman's own reporting doesn't support — those appeared in less-authoritative coverage and their absence from Gurman's account is itself a signal worth including.

Every row below is unconfirmed. Where sources disagree, we've noted the disagreement in the note rather than presenting one figure as settled.
Status
Testing stage
"Late-stage testing" per Bloomberg's Mark Gurman (Aug 5-6, 2026 report)A firmer signal than typical pre-launch leaks — Gurman reports Apple is testing Wi-Fi-only and cellular variants specifically
Performance
Chipset
New chip, successor to S10 (rumored)Series 11 and Ultra 3 both currently run the same S10 chip introduced a generation earlier — this would be the first genuine Watch performance jump in years. Leaked Apple code shows a new chip per MacRumors, but whether it's branded S11 or S12 is unclear.
Battery
Target
Longer than Series 11's 24hr (38hr Low Power Mode) ratingWeibo-sourced leak — a target, not a confirmed number
Design
Overall
No major redesign expectedGurman is direct that neither the Series 12 nor Ultra 4 gets a "major design overhaul" this year
Touch ID
Not expected — Gurman calls this unlikely, since it would itself count as a meaningful design changeCirculated based on leaked Apple code, but not corroborated by Gurman's own reporting
Blood pressure sensor
Not mentioned in Gurman's reportingAppeared in less-authoritative coverage only — the omission from Gurman's account is itself a signal, not proof it won't happen
microLED display
Not mentioned in Gurman's reportingSame caveat as the blood-pressure sensor claim
