Audemars Piguet's ref. 5273 is a very rare vintage find with elegant proportions of 34mm, and just 5.9mm in thickness. The dial displays a beautiful "Automatic" text referencing the high grade caliber 2120 it houses. This movement is historically important due to its use in both of the first series of the Royal Oak (ref. 5402), as well as the Patek Philippe Nautilus (ref. 3700). For those who appreciate the seldom seen finds, the 5273 offers a "less is more" and "no frills" design language and makes for a practical dress addition being self-winding and in stainless steel. We could not be more proud to offer this example which has remained in fantastic vintage condition with a clean dial and unpolished case!
