Re:Acceptable battery life (Score 1)

I have been wearing a kinetic Seiko Premier for the last 10 years and I totally love the idea of the spring, gears and an eccentric weight working in harmony to make a beautiful, functional, piece of jewelry.

The other big selling point for me was that changing a watch battery requires opening the seal and, unless the work is done by the manufacturer, your water-resistance guarantee just went out the window. With a kinetic, there's no reason to open the case, so my watch is as water-resistant today as it was a decade ago.

So, I've really no interest in owning a smart watch.
