Audemars Piguet Royal Oak Ref. 4100BA – 1980
The Classic Royal Oak Refined in 18k Yellow Gold
When the Ref. 4100 debuted in 1977, it marked a pivotal evolution in the Royal Oak lineage — the first to feature a central seconds hand and a more wearable 35 mm case, designed for those who found the Jumbo models too large.
Our 1980 example, the 4100BA, is the full 18k yellow gold version and comes in absolutely stunning condition. The grey petit-tapisserie dial, produced by Stern Frères, is a work of art — bearing all the rich texture and timeless charm that defines early Royal Oaks.
Powered by the automatic Caliber 2123, based on Jaeger-LeCoultre’s ultra-thin movement and custom-finished by AP, it offers performance and prestige in equal measure.
Paired with its original Royal Oak 18k gold bracelet and a signed AP clasp, this reference is a quintessential blend of sport and elegance — a golden icon for serious collectors, especially with the original Extract from Archives from Audemars Piguet.
