Everyone has a different idea of what constitutes the perfect watch. Some want one that expresses their status or taste, while others prefer something else. Celebrities are no exception to this rule. They're picky about what they wear on their wrists and often collect many different pieces over time. For example, Jay Z loves a Cartier Crash and Virat Kohli opts for a Rolex Daytona. Kylie Jenner has a white gold Patek Phillipe and George Clooney is loyal to an Omega Speedmaster.

The Audemars Piguet Royal Oak is a classic octagonal design that works for day or night. Will Smith, John Legend and Justin Bieber are all fans of the watch and have one of their own. One big draw with the Royal Oak is the many ways in which it can be customized--for example, actress Millie Bobby Brown opted for a chic steel finish with white face, while Serena Williams has a special version designed not to dig into her wrist when she's on the court. Rapper Travis Scott's Royal Oak comes with a frosted gold finish although he also owns a rare model studded with rainbow coloured sapphires.

Roger Federer, who has 20 Grand Slam titles under his belt, has quite the collection of Rolex watches. In 2009 he wore his Rolex Datejust II when he lifted the trophy after winning the French Open for the first time. The watch, similar to the trophy, is an icon for that day, bringing back memories when he wears it. Other Rolex models in his collection include a GMT-Master II “Batman”, Daytona “Big Red” and the elusive blue dial Sky-Dweller.

Rolex has been producing women's watches for decades, such as the iconic Lady-Datejust and the Ladies Oyster Perpetual. Hailey Bieber, for instance, wears an ultra-luxurious Rolex Lady-President watch with a diamond bezel on a President bracelet with semi-circular links. The 28mm case is ideal for a larger yet feminine appearance on her wrist.

Academy Award winning actress Charlize Theron's choice is the Sea-Dweller because it is extremely water resistant; she could dive to 12,800 feet if she wanted to. Other celebrities spotted wearing this model include David Beckham, Ashton Kutcher and Tom Hanks.

Bollywood actor Anushka Sharma is wearing an Audemars Piguet Royal Oak Jumbo watch. The series, since 1993, is owned by many popular celebrities all over the world and is one of the best premium luxury watch brands in the world.

Bollywood actor Shah Rukh Khan has an impressive collection of watches. The internet is swooning over a super-expensive watch he was seen wearing in a new video. The Audemars Piguet Royal Oak Perpetual Calendar is a highly sought-after luxury watch known for its intricate design and advanced technology. The Royal Oak Perpetual Calendar was one of the first luxury watches to feature a self-winding movement with a perpetual calendar mechanism, which was considered a major technological breakthrough in the world of horology. The Royal Oak Perpetual Calendar is part of the Royal Oak collection, which is considered one of the most iconic and recognizable luxury watch collections in the world. The Royal Oak collection has a rich history and continues to be a symbol of quality, precision, and luxury for Audemars Piguet.
