The reference number 15400ST.OO.1220ST.01 doesn't immediately ring a bell for the casual observer. However, for connoisseurs of horological excellence, it represents a specific iteration of one of the most iconic watches ever created: the Audemars Piguet Royal Oak. While the reference number itself might not be widely publicized, it points towards a specific configuration within the larger 15400 family, a predecessor to the currently popular 15500. Understanding this specific model requires delving into the history, design, and market value of the Audemars Piguet Royal Oak, specifically focusing on the models frequently searched for online, including the 15500 and its variations. This article will explore the nuances of the Royal Oak lineage, examining the 15400 series, the closely related 15500, and the factors influencing their prices and desirability in the secondary market.
The Royal Oak's Genesis and the Significance of the 15400 Series:
The Audemars Piguet Royal Oak, designed by Gérald Genta in 1972, revolutionized the watchmaking world. Its groundbreaking integrated bracelet and octagonal bezel, combined with its luxurious materials (typically stainless steel, gold, or a combination of both), defied the conventions of the time. The initial Royal Oaks were larger than most watches of their era, a bold statement that resonated with a new generation of watch enthusiasts.
The 15400 series represents a significant chapter in the Royal Oak's ongoing evolution. Released as a successor to earlier models, the 15400 retained the core design elements that defined the Royal Oak's iconic status while subtly refining its proportions and aesthetics. These refinements included slightly more compact dimensions compared to its predecessors, making it more comfortable for a wider range of wrists. The 15400ST.OO.1220ST.01, specifically, signifies a stainless steel version (ST), likely indicating the case material and the specific movement (1220ST) which is an automatic caliber. The "OO" likely refers to the dial configuration, indicating a specific design variation.
Comparing the 15400 and the 15500:
The Audemars Piguet 15500, the successor to the 15400, further refined the design language. The most noticeable difference lies in the slightly larger case size and subtly updated bracelet design. The 15500 also benefits from advancements in movement technology, offering improved performance and precision. However, both models share the same unmistakable Royal Oak DNA, embodying the spirit of luxury sport watches. The 15400 retains a certain charm for collectors due to its slightly more compact size and its place as a bridge between earlier generations of Royal Oaks and the contemporary 15500.
