Description

Revising my collection and this loved piece is for sale.  Audemars Piguet Royal Oak Perpetual Calendar in steel & platinum, ref 25820SP.
This watch was made in the year 2000 and comes with a special Audemars Piguet 125th Anniversary certificate.
The watch was fully serviced by AP Clearwater in early 2018.
Condition is very good with swirls/hairlines from normal wear.  Watch has the original AP signed bracelet and correct un-signed crown (this ref in 2000 did not have a signed crown, AP made signed crowns later -- I had to fight the AP Service Center to make sure that the un-signed crown was kept and it was.)
Full set includes the AP wooden watch box that is a motorized watch winder with AP outer box, AP Certificate of Origin, Instructions, AP travel case, and AP service documentation.
Price is firm.  I am not looking for trades, this is a full sale only.  Does not include shipping costs, I will work with buyer on whatever shipping options are preferred.  Thanks for reading.

📖 About This Reference

The Reference 25820SP represents Audemars Piguet's Royal Oak Offshore Chronograph in a mixed-metal configuration. This 42mm chronograph combines stainless steel and platinum case construction, distinguishing it from standard steel variants within the Offshore chronograph series. Production spanned from 2000 to 2008. The watch features a stainless steel and platinum case measuring 42mm in diameter with a fixed octagonal bezel. A black dial sits beneath sapphire crystal, while the automatic Caliber 2226/2840 movement provides chronograph functionality with a 50-hour power reserve. Water resistance is rated to 100 meters, and the watch is fitted with a rubber strap. This reference appeals to collectors seeking Royal Oak Offshore chronographs with premium mixed-metal construction. The platinum and steel combination positions it above standard steel models while maintaining the series' 42mm case size and automatic movement architecture. The eight-year production window and specific material combination define its place within the broader Offshore chronograph lineup.

Spotted this amazing Audemars Piguet Royal Oak Perpetual Calendar reference 25654ST this morning
First time I see such a dial patina on a Royal Oak. Brownish, copper, maybe burgundy sometimes with sub dial rims which are verging on the orange. This dial patina is just incredible and so desirable 😍 What do you think of it? Credit: Meertz World of Time Best wishes Alkiro

SIHH 2018 live: Audemars Piguet
Strong collection this year with a focus on the Royal Oak Offshore to celebrate the 25th anniversary. New bracelet for the Lady Millenary. For me the star of the year is the Tourbillon Chronograph which features an original dial architecture which makes me think about a fan. Another hit is the RO Pe

Audemars Piguet will officially present the Royal Oak Perpetual Calendar in a full black ceramic case and bracelet at SIHH 2017. Highly notable here is the ceramic bracelet, which along with the case, took AP some 600 hours of research and design. To assemble and finish a single black ceramic bracel

Is the Equation of Time the most under-appreciated model in the Royal Oak line-up?
I was admiring the Royal Oak EOT on the AP website and wondering to myself why the watch gets so little mention on the watch forums. My personal feeling is that additional dial colors, case material variations, and a bracelet option would spur demand for the watch. I'd especially like to see a slate
