Mechanical watches don't require sacrificing many features vs. quartz. Other than not having to wind or set it as often, the only real advantage of quartz is price.

That's what may change if these new smart watches find their killer app. No one really needed a calculator, heart beat monitor, or other gimmick on his wrist, so digital watches never pulled away on features. That might change now.

Would I rather wear an intricate piece of jewelry or see why my phone vibrated without reaching into my pocket? It starts to be a different calculation.
