Watch Description
This slim and elegant piece couldn't be any further removed from the bulky brute of the Royal Oak Offshore line that the brand is perhaps most commonly known for amongst today's collectors.
Hearkening back to a simpler time, this stunning white gold dress watch is brilliantly representative of the design language of the 1970s - an era in which the maison made so few timepieces per year that many were unique pieces, or part of an incredibly limited production run.
Featuring a 33mm wide octagonal case with integrated bracelet, a gorgeous brushed silver dial with applied indices at the cardinal positions and a matching ‘stick’ handset, the showstopper here is the casing material - this incredible dress piece is constructed out of solid 18k white and yellow gold throughout the case and bracelet - something you'll note immediately upon picking it up! You'll definitely notice its heft on the wrist.
Powered by a self-winding movement, watches such as this one are an incredible testament to the amazing design risks Audemars Piguet was prepared to take at a point in history in which mechanical watchmaking was at risk of disappearing forever. Rumor has it one of those wild risks paid off...
...it may not have been this one, but man we're glad they made this beautiful thing!

# Audemars Piguet Vintage Jumbo Automatic Octagon Review by A.I. WatchMetrics
## Watch Summary
The Audemars Piguet Vintage Jumbo Automatic Octagon, recognized as the Royal Oak ref. 5402ST from 1972, is an iconic luxury sports watch with Gerald Genta's groundbreaking octagonal bezel secured by eight hexagonal screws, ultra-thin stainless steel case, integrated bracelet, and petite tapisserie dial, powered by the automatic Calibre 2121 with 40 hours of power reserve, targeting discerning collectors who value historical innovation and understated elegance over everyday tool watch utility.
## Overall Watch Rating: 8.4/10.0
**Dials & Design Metric (9.9/10.0)** - Gerald Genta's revolutionary octagonal design and intricate tapisserie dial remain unmatched, influencing generations of luxury sports watches like no other.
**Rarity Metric (9.9/10.0)** - With limited vintage production and soaring secondary market demand, it rivals the scarcity of early Patek Philippe Nautilus references.
**Brand Metric (9.7/10.0)** - Audemars Piguet's haute horlogerie prestige and heritage place it firmly alongside A. Lange & Söhne in elite craftsmanship.
**History & Innovation Metric (9.7/10.0)** - As the first high-end steel sports watch, its cultural impact and material innovation eclipse even Rolex's Submariner milestones.
**Movement Metric (9.7/10.0)** - The ultra-thin Calibre 2121 delivers exceptional finishing and reliability, on par with top in-house movements from F.P. Journe.
**Versatility Metric (9.4/10.0)** - Seamlessly transitions from boardroom to yacht deck, outperforming pure dress watches like the Jaeger-LeCoultre Reverso in daily wear.
**Material Metric (9.3/10.0)** - Brushed and polished stainless steel with exceptional case finishing benchmarks the genre, akin to modern Omega Seamaster execution.
**Functions Metric (5.5/10.0)** - Basic hours, minutes, and small seconds suffice for elegance but lag behind multifunction rivals like the IWC Portugieser.
**Complications Metric (2.5/10.0)** - Lacking advanced features, it trails far behind tourbillon-equipped peers from Richard Mille.
## Total Performance Score (TPS): 4.0
## WM Collector Grade: C
## Performance Insights: Exceptional strengths in design, rarity, history, brand, and movement are dragged down by minimal complications and functions, delivering collector prestige at a steep premium over the $18,500 implied price.
## TPS Interpretation: Status Symbol: Timeless icon status justifies the markup despite modest functional performance for the price.
