Waltham Maxim Blue Tank

Late 1970s.
A clean rectangular tank case, all gold-tone, with soft polished lines.
The dial is blue, with a fine repeating geometric pattern across its surface.
Gold hands, a discreet signature, Swiss made.
The color shifts from steel blue to deep navy as the light moves.
Worn on its original dark blue leather strap, croc-embossed, with its original buckle.
A mechanical movement inside, wound by hand.

A splash of color on the wrist, quiet and refined.
