Apple Watch Series 2
If you're not at all interested in fitness tracking, Apple Watch Series 2 is likely about as appealing as the first-gen Watch was when it was first released. That being said, if you are a runner or swimmer this may be the push you need to get an Apple Watch.
Series 2's fitness tracking abilities give the Watch a more focused path; The awaited built-in GPS is accurate and adds another dimension to the smartwatch; Swimproof water-resistance will be welcomed by all, but swimmers will also appreciate the detailed swim tracking.
Though the Watch's appeal has broadened, it's still relatively narrow with no true "wow" feature; No notable gains in battery life or charging ability; watchOS 3 and an upgraded processor offer a great benefit to first-gen Apple Watch users as well, at a lower price.
