Will the Apple Watch SE (second generation) work with an Iphone 6S Plus running on operating system 15.6

If I am understanding this correctly, the current Apple Watch SE is the second generation.

When was the new Apple Watch SE 2 (2022) released?

Apple officially announced the second-gen Watch SE at its ‘Far Out’ event on 7 September, alongside the Watch Series 8 and brand new Watch Ultra.

That being the case, the new Apple Watch SE specs page says: New Apple Watches require an iPhone 8 or later with iOS 16 or later.

Perhaps you should contact support (Get Support at the top of the page) to be sure.

Thanks for your reply. I have another question because I am clueless about this. If I purchase a brand new SE watch will it automatically be watchOS 9.

Sorry, missed the "Second Generation" bit.

Yes the new Apple Watch SE second gen will come pre-installed with iOS 9, so will not work with an iPhone running iOS 15.6.

The iPhone 6s Plus can't be updated to iOS 16.

If its running watchOS 8 or earlier yes, it should work fine.

If its been updated to watchOS 9, then no.

Yes.
