Most expensive watch in the world

As of my last update in January 2022, one of the most expensive watches in the world is the "Graff Diamonds Hallucination." This watch is known for its extravagant design and features over 110 carats of rare colored diamonds set in a platinum bracelet. It was valued at over $55 million, making it one of the most expensive watches ever created.

It's worth noting that the prices of luxury watches can fluctuate over time, and new, even more expensive timepieces may have been released since my last update. Additionally, the value of watches can vary depending on factors such as brand prestige, rarity, craftsmanship, and the quality and quantity of precious materials used.
