Introduction
Understated in its design, the Audemars Piguet ref. 5273 is a round 34mm stainless steel timepiece with one of Audemars Piguet’s most historically important movements powering it. Working with fellow watchmakers Jaeger LeCoultre and Vacheron Constantin since 1966 to develop an ultra-thin automatic movement, Audemars Piguet was able to release one of the world’s thinnest automatic movements in 1967. Famed for featuring a peripheral winding rotor that rides a rail along the outside of the movement, the cal. 2120 was able to achieve a 2.45mm thickness which was a record that remained intact until the new millennium. Used in the Royal Oak in 1972, the cal. 2120 has proven to become one of Audemars Piguet’s most historically important movements and thus, by extension, the ref. 5273 remains incredibly valuable to the brand’s heritage.

THE DIAL
The dial features Roman Numerals in black on a silvered-white surface. The hands are also black, making them more visible against the light colored dial.

THE MOVEMENT
Housed underneath the screw-down caseback is the legendary 2120. The very same ultra-slim movement that powers the Royal Oak 5402 and Patek Philippe Nautilus 3700.

TIMING MACHINE READOUT
This reading was taken (crown down) with a ONEOF Accuracy Boutique Edition timing machine at time of cataloging. It is provided as a courtesy only, and shall not be construed as a warranty or guarantee of any kind. Please refer to our terms and conditions of sale for more information.
Condition
The overall condition of the watch is excellent. Original and rare silver dial is in near-mint condition, with only minor surface abrasions (on the right side of the word Automatic). Case appears to have no signs of previous polishing. A few light abrasions can be seen on the case back, however the serial number is very strong and visible. Strap and 18k white gold buckle are original to the watch.
Please Note: Due to CITES considerations, if the watch is to be shipped outside of the USA, an alternative leather strap to the existing exotic version, shall be provided.
Our Perspective
This early example 5273 really is a discreet watch that packs quite a punch. A slim 6mm thick, the watch not only houses the Cal. 2120 (same movement as the Royal Oak 5402 and the Patek 3700), but also features a screwback case design. We love the Roman numerals on the dial, which are much far more unusual than the normal stick indexes.
