Audemars Piguet Royal Oak - Foundation Dial

The Audemars Piguet Royal Oak reference 15100ST "Foundation Time for the Trees" is a limited-edition model introduced in 1999 to support the Audemars Piguet Foundation's environmental initiatives. Only 450 pieces were created, 400 in stainless steel and 50 in 18k gold. This collaboration aimed to raise awareness and funds for reforestation and forest conservation efforts globally.

What Makes the 15100ST Foundation Dial Special

Unique Dial Design. At first glance, the 15100ST appears to be a standard Royal Oak with its signature blue "Grande Tapisserie" pattern. However, upon closer inspection, the dial features a subtle oak tree motif at the center, symbolizing the foundation's mission. This design choice reinforces the connection between the timepiece and the environmental cause it supports.

Limited Production Only 450 stainless steel and 50 18k gold versions of this model were produced, making it a rare collector's item. The limited run adds to its exclusivity and desirability among watch enthusiasts.

Transparent Case Back For the first time in Royal Oak history, this model featured a transparent case back, allowing wearers to view the movement inside. The case back showcases a gold oscillating weight adorned with the AP logo and oak leaf motif, further emphasizing the foundation's connection. This design choice was a significant departure from the traditional solid case backs of previous Royal Oak models.

Movement and Specifications The 15100ST is powered by the Audemars Piguet Caliber 2225, a self-winding movement derived from the Jaeger-LeCoultre Caliber 889. It operates at 28,800 vibrations per hour and offers a power reserve of approximately 40 hours. The 36mm stainless steel case is paired with a matching steel bracelet, maintaining the Royal Oak's signature integrated design.

Auction Performance Due to its rarity and unique design, the 15100ST has garnered significant attention in the secondary market. For instance, a model sold at Monaco Legend Auctions in 2022 for €104,000, well above its estimated value of €50,000–€100,000, highlighting its status as a sought-after collector's piece.

Legacy and Impact

The Royal Oak 15100ST "Foundation Time for the Trees" serves as a testament to Audemars Piguet's commitment to environmental conservation. By integrating a meaningful cause into a luxury timepiece, the brand has created a lasting symbol of its dedication to sustainability. The model's unique design elements and limited production ensure its place as a significant piece in the history of the Royal Oak collection.

This particular example is in unpolished and overall great condition. The case is very sharp and clean, the bezel and bracelet show normal signs of wear. The grand tapisserie blue foundation dial is mint condition. It also features an open caseback, quickset dat function, and signed AP crown.

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….
