Reasons to Bid
The Audemars Piguet Royal Oak Ref. 4100SA is a notable expression of the brand’s integrated sports-watch design, here executed in a refined two-tone steel and yellow-gold construction. This pairing blends everyday robustness with a touch of luxury, reflecting the context in which the model was originally created. The watch carries all the defining Royal Oak elements: the octagonal bezel with eight hexagonal screws, the octagonal cushion case, and the integrated bracelet that tapers fluidly from the mid-case to the clasp. The steel-and-gold contrast adds visual depth while preserving the sporty character of the Royal Oak line. The dial features the anthracite Petite Tapisserie guilloche pattern, complemented by applied gold markers and luminescent gold hands for clear legibility. Inside the case sits the automatic Caliber 2125/2800, derived from the renowned Jaeger-LeCoultre 920 ébauche and further refined by Audemars Piguet.
