Apple Watch to adopt new band system and larger battery in 2027 redesign

Chinese leaker Instant Digital posted on Weibo that Apple plans a major redesign of its Apple Watch for 2027, likely the Series 13. The redesign would replace the existing band‑attachment mechanism with a new system—potentially magnetic—making current bands incompatible. The change is intended to free internal space for a larger battery, improving endurance. The rumor echoes the “Apple Watch X” concept first reported in 2023, which promised a thinner case, new band connection, and micro‑LED display but was not realized in the Series 10. Apple’s 2026 releases are expected to be incremental, with the Series 12 being a modest update and the Ultra 4 receiving modest upgrades, while the substantive redesign is slated for the following year. If true, the new attachment could disrupt a decade‑long accessories ecosystem, prompting users to wait before purchasing a new watch.

The anticipated redesign may also bring internal hardware improvements such as upgraded health sensors and enhanced AI processing, though details remain unconfirmed. Analysts note that Apple often staggers major innovations across product cycles, focusing this year on iPhone and iPad updates, and reserving a significant watch overhaul for 2027.
