About the Royal Pop Series
The Royal Pop is a deliberate mashup — the 1972 Gérald Genta-designed Audemars Piguet Royal Oak meets the irreverent 1980s Pop Swatch interchangeable-case format. Where the original Pop Swatch swapped plastic cases on a wrist strap, Royal Pop reimagines the format as a Bioceramic pocket watch you can convert with a lanyard or chain. Eight colorways, each named for the number eight in a different language.
