Audemars Piguet Quantieme Perpetual Calendar Moonphase 25548BA - 18K Yellow Gold

Trade In
Details

High Complication, Human Scale

Before the Royal Oak, Audemars Piguet built its reputation on classical watchmaking of the highest order. The Quantieme Perpetual is a direct link to that heritage. It houses one of the most respected and difficult complications in horology within a restrained, elegant yellow gold case. This is a pure expression of AP’s technical mastery, offering a level of craft and complexity that directly rivals its peers from Patek Philippe, often for a fraction of the cost.

Classic Proportions, Total Functionality

This reference 25548BA is defined by its balance. The 35.5mm case is a perfect size for a complicated dress watch, providing presence without being oversized. The white dial, with its applied baton markers, is clean and highly legible, allowing the perpetual calendar and moonphase displays to be read at a glance. It's a thoughtful design that prioritizes function over ornamentation.

Clean Dial And An Original Buckle

The watch is in good condition. The 18K yellow gold case is unpolished and shows honest wear consistent with its age. The white dial and the crystal are both in great shape, with the intricate printing remaining crisp and clear. The watch is fitted to a new leather strap that secures with the original 18K gold Audemars Piguet buckle, an important detail that preserves the watch's integrity. As with every watch we offer, this piece has been verified as mechanically sound and is ready to wear.

The Thinking Collector's Perpetual

This is a watch for someone who understands watchmaking beyond the hype. It delivers a Holy Trinity perpetual calendar in a timeless package, representing one of the smartest buys in high horology. It wears beautifully, slides under a cuff with ease, and carries the weight of a true manufacture. It's a confident choice for the collector who values substance over spectacle.

What Our Clients Say About Us

Dan Young

I knew I was gonna like Danny, based on his name, but nothing could’ve prepared me for how great of an experience this was. He had the most beautiful 70s Seamaster Cosmic on his website and I was set to be married 2 days later - I arranged to buy it but before leaving we both realized it needed to be serviced. I panicked, because I was literally buying this for my wedding, and Danny being the legend he is, loaned me a nearly identical Seamaster to make sure I could get through the event Never have I had someone go so above and beyond for me, especially while purchasing one of the lesser priced items in their inventory. He serviced my watch and exchanged it with me after the wedding on a super fast turnaround timeline. I would sincerely recommend you visit this guy, you will not be disappointed Edit: adding a pic of the loaner (two tone) and the owner (crosshair)

Great service and shop. Danny and his team were incredibly accommodating, professional, and kind. Great selection of vintage watches. Their store is the hidden gem in the diamond district.

This was my first real luxury watch purchase, a Rolex 15200 Date 34mm, I own Tissots and a Laco, but those are entry level luxury watches. I found Danny’s Vintage Watches online, and had great feedback both on Google, Chrono24 and the Reddit watch community. So decided to give him a shot as buying online can be a crap shoot. Ordered Monday night, was at my doorstep Friday morning. Despite the watch being over 30 years old, serial number says it’s from 91, the watch looked new. Didn’t come with box or papers, and was shipped in a plastic sleeve wrapped in bubble wrap. Danny was always available to answer questions. I’ll be buying from Danny again for the next purchase…saw a couple of Speedmasters on his site I liked….
