Machined and engraved barrel bridge

 
These 3 bridges have not been finished yet. They hold both the counting and the power reserve indicator trains together.

The differential gear transmits the rotation of the barrel to the hand of the power reserve indicator. This is done without any influence on the running of the movement.

 
Winding-mechanism: mechanism holding 2 functions, one for the hour-setting and one for the winding.

Function: to achieve the 1/12 ratio between the minute-hand and the hour-hand of the flyback.

 
Base plate: decorated (satin-brushed and black gold) and pre-mounted (assembly of the jewels, wheels and pins)

The center wheel holds the hour hands. It makes one rotation every 12 hours.

This bridge has been treated in black gold.
