The 5127 exudes sensuality. Not a sharp edge to be found on the curvaceous case. Perhaps the original Galet if you understand the reference.
A generation when the name "Patek Philippe" was very subtly printed on the dial. Perhaps only the wearer could read the important marquee.

The side profiles show a case that harmonizes with the wrist. The watch is so very svelte and easy to wear, yet its medium size gives the feeling of density and weight from the white gold, rhodium plated case.
