Anant Ambani, the youngest son of Mukesh Ambani and Nita Ambani, is known for his impressive watch collection, which includes pieces from renowned luxury brands like Richard Mille, Patek Philippe, and Audemars Piguet. Recently, he caught attention when he wore an extraordinarily rare watch during an outing with Radhika Merchant: the Richard Mille RM 52-04 "Skull" Blue Sapphire, one of the world's rarest timepieces.

This limited-edition Richard Mille watch is valued at ₹22 crore, or approximately USD 2.6 million. The RM 52-04 "Skull" Blue Sapphire is crafted from a single piece of sapphire, featuring a unique design with a pirate skull and crossbones in the tonneau-shaped case. The watch's back showcases the skull, which is part of the movement, visible through the sapphire caseback. The four "bones" of the pirate flag are represented by the bridges that connect the movement to the case. Only three of these watches have ever been made, making it an exclusive and highly coveted item among collectors.

Richard Mille is a prestigious Swiss watchmaking brand known for its exorbitant prices and innovative designs, making it a status symbol among the rich and famous. Anant Ambani, who is also a horologist, has established himself as a connoisseur of luxury timepieces. He married Radhika Merchant in July 2024, and together they form part of the influential Ambani family, which includes his siblings Isha and Akash Ambani.
