Re: Equation of time
The Gyro1 has a running equation of time complication.
A regular EoT watch needs you to manually add/minus the 15 minutes to get actual solar time. But a running EoT shows the actual solar time directly on the dial for convenience. This is more complex as it needs a set of differential gears between the geartrains, versus a regular EoT which "only" needs an annual cam and lever setup. The differential is just visible on the openworked dial face.
Other examples of running EoT include Breguet Marine Equation Marchante, and the Vianney Halter Classic Janvier.

Questions re Gyrotourbillon 1 complications
Would like to reach out for help: Does Gyro 1 have a day (i.e. Mon, Tue, etc.) function? Does it have a month indicator both on the dial front and at the back? How does one read the equation of time function on the dial? Thanks very much.
Some answers....
No Day indicator. The month indicators are on the dial side AND the movement side. The equation of time is easy to read: It is displayed on the dial dedicated to time, and represented by the hand ending with the sun. So you can read the Equation of time a...
Thanks very much Nicolas....but from your pics,
the month on the dial side shows Oct while the month on the movement reads between Aug and Sep. Just want to make sure I am reading the correct information.... Also, other equation of time pieces such as AP's has a +15 to -15 indicator along with the equa...
