Audemars Piguet ROO Perpetual Calendar Chronograph

[ninja]

Just thought of sharing the final (I hope!!!) installment in my quest to collect AP ROOs
Had the opportunity to get this "rare bird" from a very good friend

It's an Audemars Piguet Royal Oak Offshore Perpetual Calendar in Titanium
Excuse the poor quality I-phone picture. Couldn't resist the excitement
More pictures to come....

Just Perpetual Chronograph no "Annual" in between. Annual Calendar is another thing altogether

[bezelnut]

Dear Mr Tyler, can you please explain the difference between perpetual & annual calender?

Thanks.

[Godzillaz]

Here's a basic rundown. (Typical date adjustment for mechanical wristwatch)

Simple Calendar: Require 5 adjustment in a year.
specifically on
Feb 28/29 to Mar 1,
April 30 to May 1,
June 30 to July 1,
Sep 30 to 1 Oct and
Nov 30 to Dec 1

Annual Calendar: Require only 1 adjustment in a year, Feb 28/29 to Mar 1. It knows to jump from 30th to 1st if is on those shorter month.

Perpetual Calendar: No adjustment needed as in recognize all the months and leap year.

Hmm, if I'm not mistaken the perpetual calendar will need correction in the year 2100 because it won't be a leap year that year.

[CKL1213]

don't worry about 2100, you and everyone else here will be long gone

[AsherLim]

Haha, yeah. I guess that's something for our children and grandchildren to worry about!

[Godzillaz]

I worry more about whether the watch will survive that long ...

[AsherLim]

Hmm, good point! Haha, but if taken good care of and with regular servicing should be ok right? Haha, I don't know. Kinda new.

Thank you Mr Tyler.

So now I'm confused, what does the Perpetual actually means on a Rolex?

In Rolex's terms, perpetual simply mean self-winding.
