Silent minute repeater: hammers strike, ripples count hours and minutes.
A minute repeater you can see but not hear. Half a minute after the hands move, the hammers in the bay at six strike and the time is counted in ripples across the enamel: one ring per hour, paired rings per quarter, fine rings for the minutes past the quarter. Then the dial is still again.
Sunburst guilloché enamel, faceted batons, gong wires round the edge, a power-reserve subdial for the battery and a date window at half past four. Five enamels, from charcoal to navy, burgundy, pine and graphite.
For Wear OS 4 and newer.
