Waltham Monte Carlo Gold Onyx

1970s.
A rectangular case with cut corners, all gold-tone, from Waltham's most confidential line.
The bezel is worked with a fine bark finish texture, catching the light in tiny horizontal lines.
The dial is deep black onyx, framed by gold, with slim gold dauphine hands.
A blue cabochon set into the crown.
A mechanical movement inside, wound by hand.

Black that holds the light, and gives nothing back.
