It’s hard to say without having the watch in hand, but it seems like legibility should be fairly straightforward and clear after a period of adjustment. The largest circle, extending all the way to the outer edge of the dial, is a running seconds indicator, with the mid sized circle counting off minutes and the smallest providing the hours. I would imagine that in motion the sweep of that large circular seconds indicator holds a lot of visual interest. If you’re used to a traditional second hand (as I’m sure we all are) it’s certainly going to be a very different experience to check the time, at the very least.
The Union Collection actually consists of two smaller mini collections. The Rive Gauche line has a flat dial in blue, black, and two shades of white. The Rive Droit line has a vintage style curved dial in blue, green, or red. The watches measure 39mm in diameter and use the Miyota 9015 automatic movement. Prices range from 740 to 790 Euros.
