This watch is also known as:
266.21.70, 2662170 .
Two back-to-back dials and two sets of hands turning in opposite directions, while driven by a single movement. On the front, a small seconds hand gently marks off the passing moments of daily life on the satin-brushed dial. On the back, its other face offers a scintillating contrast with an Art Deco inspired dial lit up with diamonds.
