Waltham Lady Maxim Tiger Eye 70'

Late 1970s.
A small octagonal case with cut corners, all gold-tone, framing a dial like no other.
The dial is natural tiger eye stone, deep brown with green accents and black, with golden bands that shift as the light moves across them.
Gold Roman numerals, gold hands, a quiet signature at the center.
No two stones are ever alike, each dial is one of a kind.
Worn on a fine mesh bracelet, freely adjustable to fit any wrist.
A mechanical movement inside, controlled and regulated.

The stone shifts with every movement of the light.
