SOLD – 1977 Audemars Piguet Stainless Steel Ref. 4010ST


Out of stock


This rare Audemars Piguet reference 4010ST from 1977 features a stainless steel octagonal case measuring 34mm in width. The original dial and case are presented in excellent condition. It is complimented by a brand new Audemars Piguet alligator strap and AP signed stainless steel pin buckle.

This is an unusual dress watch firstly for being made in stainless steel and then for its octagonal shaped case. The watch is powered by the famous Jaeger-LeCoultre base cal. 920 movement, developed in 1967. Audemars Piguet renamed the movement as a cal. 2120 and with various changes is still in production today. The Audemars Piguet cal. 2121 based on the cal. 2120 was the original movement first used in the first Royal Oak ref. 5402. Taking into consideration the specifications and design of this watch we see it as the perfect accompaniment or alternative to a Royal Oak.

Overall this is an excellent original example and is accompanied by AP extract of the archives. 


Audemars Piguet








The Jaeger-LeCoultre cal. 920 is arguably one of the most important movements of the 20th Century. This was the same base movement that was supplied to Audemars Piguet for the first Royal Oak, ref. 5402. The cal. 920 was never used by Jaeger-LeCoultre themselves but sold to the brands such as Patek Philippe, Audmears Piguet and Vacheron Constantin.

The cal. 920 was later used in the worlds thinnest automatic perpetual calendar available on the market in 1978, this was the ref. 5548 by Audemars Piguet, this was the watch that saved Audemars Piguet during the quartz crisis. The 920 is still the worlds thinnest automatic movement in the world with a full-size rotor. Some example of watches that still used this calibre in the past: 1976 Patek Philippe Nautilus ref. 3700/1A, 1977 Vacheron Constantin 222, 1972 Audemars Piguet Royal Oak ref. 5402. In 2000, when Audemars Piguet sold their 40% stake in Jaeger-LeCoultre to Richemont group, Audemars Piguet negotiated to keep the rights to manufacture the cal. 920. Audemars Piguet have used this movement in the majority of their perpetual calendar watches today.
