About speculative execution vulnerabilities in ARM-based and Intel CPUs

I think it's only Meltdown that the watch isn't affected by.

It sounds like it is potentially affected by Spectre, especially since they say they will be continuing to develop mitigations for WatchOS.

The surprising thing to me is that they patched iOS to mitigate Meltdown. Before now, I thought it was only Intel chips that were affected by Meltdown, but I guess Apple's own A-series processors are affected too.

Yes some ARM Cortex A-series are affected by a variant of Meltdown. https://developer.arm.com/support/security-update
