Object description

Dial and Hands

The periphery of the dial features a printed outer minute track. The dial houses two sub-dials: a running seconds register at the 6 o'clock position and an elapsed minute counter for the chronograph function at the 12 o'clock position.

The display is completed by blue steel moon hands. The dial is signed "Patek Philippe & Cie Genéve" in the center. The chronograph function is integrated into the manual movement, controlled via the crown and a pusher mechanism visible on the side of the 18ct yellow gold case.
