Apple has pushed watchOS 26.3 RC to developers, a clear sign the 26.3 beta cycle is winding down. The release candidate is typically the final build that ships publicly, unless last-minute bugs force a revised RC.
The watchOS 26.3 RC build number is 23S618, replacing the prior beta 3 build.
If testing goes smoothly, the public rollout usually follows soon after an RC lands. Recent reporting expects a release as early as next week.

What’s changed in watchOS 26.3 RC
So far, this 26.3 cycle looks light on user-facing additions, and early coverage says nothing major has surfaced in watchOS 26.3.
Even when the feature list stays quiet, RC builds usually focus on tightening reliability. Expect the usual mix of fixes that improve day-to-day stability, especially after a short beta cycle.
Apple typically bundles security work into point releases, even when it does not highlight every change in public notes right away.
What’s next after 26.3
Once watchOS 26.3 ships publicly, attention shifts to 26.4 betas. Separately, recent reporting says Apple plans a Gemini-powered Siri preview in the second half of February, with iOS 26.4 positioned as the software release that introduces the next-generation Siri experience.
