Apple Tests Series 12 and Ultra 4 Ahead of September Launch

Apple is focusing on an internal chip upgrade plus improved fitness tracking rather than an exterior redesign.

Overview

  • Citing July 26 reporting, Bloomberg’s Mark Gurman says Apple is in late-stage testing of three watches codenamed N237, N238 (Series 12 Wi‑Fi and cellular) and N240 (Ultra 4) for a likely September reveal.
  • Multiple outlets report there will be no major visible redesign this year, with the new models expected to resemble the current Series 11 and Ultra 3.
  • The most notable change is an updated S‑series processor that is expected to provide a measurable boost in speed along with software and tracking improvements for health and fitness.
  • Apple is not expected to ship a new Apple Watch SE in 2026, and persistent claims about Touch ID, a new band‑attachment system, or a large jump in sensor count remain unverified.
  • Work on bigger changes continues: Apple is developing a broader watch redesign and a non‑invasive blood‑glucose detection project that sources say is a multi‑year effort aimed for later this decade.
