I think you could download and install pedometer++ for free from the app store and it has a complication that can be set to show the current number of daily steps on the watch face of your choice.
That said I highly encourage the use of the Apple Watch rings... for me the "Move" ring (red) is a revelation compared to steps because as we all know, steps aren't created equal... a walking step does less than a running step, and a bike, swimming or weight lifting workout does great things for you but hardly adds to steps... the Apple Watch converts EVERYTHING you do to calories burned from motion ("active calories") as the great equalizer which is seen in the form of a daily "Move" goal.
