Before dissecting the world of fakes, it’s crucial to understand what makes a genuine "bust down AP" so desirable. The term "bust down" refers to the aftermarket process of encrusting a luxury watch, typically an Audemars Piguet Royal Oak or Royal Oak Offshore, with diamonds. This isn't a standard factory option from AP in most cases, but rather a customization performed by specialized jewelers. The process involves meticulously setting hundreds, sometimes thousands, of diamonds onto the watch case, bracelet, and even the dial. The result is a dazzling display of brilliance, transforming an already prestigious timepiece into an even more extravagant statement piece. Key characteristics of a genuine bust down AP include: Authentic Audemars Piguet Watch: The foundation is always a genuine AP watch, meticulously crafted with high-quality materials and movements. High-Quality Diamonds: Reputable jewelers use ethically sourced, high-grade diamonds, carefully selected for their cut, clarity, color, and carat weight. Expert Craftsmanship: The diamond setting is performed by skilled artisans with years of experience, ensuring precise and secure placement of each stone. The setting styles are often intricate, maximizing light reflection and brilliance. Significant Value: Genuine bust down APs are incredibly expensive. The cost encompasses the original watch, the price of high-quality diamonds, and the labor-intensive setting process. These watches can easily range from hundreds of thousands to millions of dollars. Status Symbol: Owning a genuine bust down AP is a powerful statement of wealth, success, and discerning taste. This understanding of the real deal is essential to appreciate the stark contrast and inherent flaws of their fake counterparts.
