Audemars Piguet - Question on AP RO Perpetual Calendar

Question on AP RO Perpetual Calendar

I am considering a SS RO perpetual calendar with dark blue dial.

I would be grateful if any of the forum members, especially those who know or own this particular watch, could confirm how often would a Royal Oak Perpetual Calendar (caliber 2120-2802) need to be adjusted, provided it was kept constantly running. My understanding is that it would only require a single correction every 100 years.

The RO case is very wearable, but would this complication be robust enough for frequent use?

As an additional, less pungent question, how are those hexagonal screws tightened into their slots in the bezel of the RO???

Any comments or pictures from owners regarding the watch and/or the bracelet would be of great value.

Thanks in advance.

Regards,

BCL

Hi BCL, I had an older RO Perpetual Calendar in yellow gold. It was my first watch in all YG. It had a nice heft to it without being too chunky. I ended up parting with it to upgrade for a S/S RO perpetual in dark blue/grey (newer version with leap year i...

The AP perpetual is easy to wear.

The size is great IMO. Seems to be pretty durable and very accurate. JerryW
