is this the subforum for perpetual calendar watches?
There are a couple of threads in this forum but no subforums dedicaticated to PCs
Tried searching. Couldnt find one on PCs in general.
Here’s my first mechanical PC. Just arrived today. Hoping to get at least one more.
Congrats, a perpetual complication is a thing of marvel.

How do you deal with the +/- on accuracy? Even a 1s deviation per day would amount to a minute in two months.
You adjust the time periodically?
Slightly peeves me as i had this notion that for perpetual calendars, set it once and no need to adjust ever.
Even the paper calendar hanging on my wall I have to adjust once a month, and replace once a year.
OTOH, unless your watch is electronic (and synced with an external time source) you're still going to have issues with leap seconds and the like. I don't know that true perpetual calendars of the kind you describe even exist.
A perpetual calendar's time keeping accuracy is no better than any other equivalent quality time only watch, you still have to periodically reset the time just like any other watch as it drifts over time. It's the calendar functions that never need adjusting as long as you keep wearing it. You will have to adjust manually the calendar in 2100 as there is no Feb 29 that year so your son, grandson or great grandson will have to plan for it.
Ty sirs. My first mechanical PC. So learning along the way.
So still makes sense to put in a winder so just minor adjustments every two months or so.
