Vintage 1973

Audemars Piguet 18ct Solid Gold "Ultra Slim" Dress watch

 Caliber A/P K2120 The World's thinnest Automatic caliber.

 

ALL original all signed and matching serial numbers (case to dial dial to movement etc) original box and purchase papers (this IS very rare) good condition strap micro link "shark mesh" to rear Linen texture to front and matching texture to main body, the watch looks like it would be rough to the touch, but no it is very smooth, 
A very clever Fluid design. Outstanding Gold craftsmanship from the world's most renown of watchmakers. but the watch is so much more than just a show piece, Housing the World's slimmest Automatic Caliber (aside from the very odd and basically completely unworkable Lassale calibre 2000) with its 21 carat solid gold Rotor 36 Jewels and Special screwless balance a heart of this watch beating at 19,800 beats per hour. 

 

(remember we are using a macro lens so any and all imperfections are massively amplified above and beyond what you could see with the naked eye)

The watch weighs 86grams *approximate weight a mere 6mm depth In outstanding condition no evident wear or over polishing this watch is as stunning now as it was when purchased in 1973 (with paperwork correspondence)

 

The Dial

 This is a subtle tone satin gold dial featuring applied facets in gold and delicate black inlays, Black hour and minute hands.

Simply an iconic and classic Audemars Piguet Dial clean and crisp acclaimed for purity of design.

 

Strap

The strap is integrated to the watch in solid 18k gold and come complete with its AP logo on the deployment clasp everything is signed and hallmarked. an unrivaled liquidity in design each micro link lining perfectly to give an overall Linen or even gold denim texture throughout this historically important timepiece.

 

The Movement History

The 2120 has an interesting history; it was actually made by Jaeger-LeCoultre as the cal. 920 and it was used by Audemars (as the 2120) by Patek (in the Nautilus, as the calibre 28-255) and by Vacheron Constantin as the calibre 1120. It was the first movement Audemars Piguet used in the Royal Oak, as well.

Oddly enough, Jaeger never used it themselves. It was the world’s thinnest full rotor self-winding movement when it was introduced and it still is today. (bar aforementioned useless flawed and frankly discounted lessale 2000 that is frankly often and understandably so discounted from the horological history books)
