There are three main Apple Watch Variants.
1) First gen Apple watch - the old one
2) New Series 1 Apple Watch - plus Dual core
3) New Series 2 Apple Watch - plus Dual Core + GPS + waterproof
Each have 38 or 42mm, and each have Aluminium or Stainless Steel/Rose Gold etc.
John Lewis is selling the 38mm Series 2 Aluminium watch for £369.99.
However, they have incorrectly listed their Series 1 Aluminium watch as a Series 2 and selling at £269.00.
If you open the product description section it says it's a Series 1.
However, the title and check out and email confirmation all refer to it as a Series 2 watch.
Hopefully this will go through. I ordered 4 on Saturday and the emails have so far all been pointing to the Series 2.
Will update when i get the physical devices.
Needless to say, if this pulls through as a series 2, with JL 2 years care, at £100off...that's a hot deal IMO.
