Response to Equation du Temps Model

While the Earth rotates on its own axis, it revolves around the sun in an irregular elliptical path.
This is the reason that the solar day is not 24 hours we assume but ranges between 23 hours
44 minutes (November 3rd) and 24 hours 14 minutes (February 12th).

Jaquet Droz Equation du Temps illustrates this difference between the true solar time and solar
mean time beautifully as indicated by the blued steel hand with "sun" tip in two shades of gold
running over the slate-grey dial.

The conventional mean solar time are indicated by the very refined blued steel hands. The two
date and month subdials in the shape of opaline silver circles barely touching each other, are
united by an applied metal ring, secured by blued-steel screws.

The Jaquet Droz calibre 3666-4 is based on the Piguet ebauche. The beauty is visible through
the sapphire case-back. It is self-winding, double barrel movement with 72-hour power reserve.
This White Gold watch is a limited edition of only 28 pieces worldwide.
