today, I found this little beauty.
42mm of annual calendar, equation of time and minute repeater.
For the elegantly proportioned dial, a silvered sunburst decor has been chosen as a background to the various time indications. Surrounded by solid gold applique hour-markers with sharply defined profiles, the various indications perform their functions as the hours and minutes hands pursue their paths above them. The eye is immediately caught by the imposing date located at 1:30 on the dial. The month is displayed in a window opposite to complete the Annual Calendar function. This ingenious construction only requires a single adjustment of the date per year, in February, which is easily carried out through the watch's crown.
Striking mechanism: repeating with two facing hammers, hours, quarterhours, minutes. Regulation of the speed of the striking-mechanism by inertia-driven governor, countersprings accessible on the bridge stide, inverted minute rack; conventional gong pitches.
