Gold Plated Dime is a watch face for Android Wear 2.0 that displays the time as groups of dots. Just count the dots for each numeral, easy!

Complications are also supported and tappable; long press to configure it to any complication provider you've installed.

You should be able to install it directly from any 2.0+ watch, no phone required. It's simple, free, and only 1mb; its dark style is a good fit for the Wear 2.0 look, it supports ambient mode and should not affect your battery life at all.
