If you are absolutely sure you are never going to buy an Apple Watch — and certainly not version 1.0 — you can stop reading right now.
But if you’re an early adopter like me — or a reseller working the global arbitrage — and you can’t decide without physically weighing the 38 combinations of size, material and band, you’re out of luck.

The Guided Tours, the alloy videos, the TV ads now in heavy rotation may be as close as most buyers are going to get to the Watch itself for some time.
