Toledo moon phase system

I read the following on another site

"most moonphase discs are coupled with a star wheel of 59 teeth. this is convenient for a simple phase change as the driving wheel has a pin to move the star from the hour wheel and is known as simple moonphase .it allows for 44 min 2.8 seconds a month and 9 or so hours a year , so it has to be manually reset @ 3 years to correct one lunation period ,or one 29.53 days . if coupoled with a more astronomic gear system ,the day star has a 16 tooth pinion mounted to it which turns an intermediate 16 tooth pinion into a moon disc with 135 teeth , and now an error of 11 min and26.4 sec
per year , and so has to be corrected only once in 114 years . there are also full astronomically designed systems where corrections are needed @ 2700 years apart"


Would it be possible to ask VC's tech staff to describe how the moon phase is indexed on the Toledo?


I'll ask and get back to you on this (nt)

the Toledo has the 1st system described with a 59 tooth

wheel thus needing adjustment every 3 years.
Appreciate it
