With vintage Royal Oaks immensely sought-after, no wonder this ultra slim 1978 ref. 4100ST is the only example for sale in the UK.

The deep-blue miniature tapisserie dial has subtle guilloché, offering all the charm of the original 5402ST Royal Oak, but in a more discreet 36mm size. In excellent condition, it retains sharp case lines & beautifully finished octagonal bezel (still nice and thick), just the way we like to see them, and its original 'type 1' Royal Oak integrated bracelet. 

Fully serviced and checked by Audemars Piguet, powered by AP's self-winding calibre 2123 movement, waterproof to 50m and accompanied by its AP service pouch, AP service papers from Nov 2020, and Audemars Piguet extract from archive confirming original sale in October 1978.
