Our remarks

We can offer you this very good vintage AUDEMARS PIGUET ROYAL OAK Man Size, ref. 4100ST.OO.0477ST.A, in stainless steel with its steel bracelet.

Manufactured in around 1978 - just returned from AP service in june 2022.

This 4100 was the first Non-JUMBO gentlemans ROYAL OAK automatic watch with a smaller 35,5mm case instead of the 39mm.

Today it´s a wanted collectors piece, especially with fresh service.

Great 1970s watch icon for him or her - Gerald Genta design.


Still under AP warranty for 12 month.
