As the Queen of England, Queen Elizabeth II, 92, is the owner of countless jewels – such as the Japanese Pearl Choker and the Russian Fringe Tiara.
Among her collection is an incredible diamond-set watch, which she wore on her Coronation Day back in 1953.
Meghan Markle, 37, famously borrowed a tiara from Queen Elizabeth’s private collection of jewels when she married the royal’s grandson Prince Harry, 34, back in May this year.
And now, watch brand Bucherer have offered Express.co.uk some insight into how two of the royals’ timepieces compare.
Two stylists revealed why Meghan Markle doesn’t wear the Queen’s jewellery like Kate Middleton does.
So, let’s take a closer look at the experts’ in-depth review of what the famous pair have worn on their wrists.
The Duchess of Sussex is the owner of a Cartier Tank Francaise watch – which is said to be her favourite.
The item is of great sentimental value, being the present that the former actor bought herself as a present in celebration of her former show Suits reaching a milestone moment.
According to experts, the timepiece’s elegant design makes it one of the most classic watches out there, Bucherer said.
“Newer versions of the watch retain the original elements of the original Tank design – which was influenced by military tanks from the WWI period and dates back to 1919,” they added.
An update to the classic Tank style, the Francaise timepieces feature precise quartz movement as well as a metal linked bracelet.
In addition, the curved case is set at the centre of the bracelet, seamlessly mimicking its lines – meaning its not dissimilar to the classic design, but with a modern finish.
Meanwhile, Queen Elizabeth II is the owner of an extraordinary Jaeger-LeCoultre Calibre 101.
She wore the timepiece to her coronation at the age of 25.
The Calibre 101 holds a record – in that it houses the smallest mechanical movement to have ever been created.
In celebration of 60 years of her reign, the Swiss watch company presented her with a new 101 creation.
The original watch was created in 1929, Bucherer said, with the “idea of creating a precise and dainty accessory that could tell the time”.
Its record-breaking small movement “encapsulated delicacy and femininity” – as well as giving in-house designers “room to fuse high-end jewellery with horology”.
In the Luxury Swiss Jeweller’s report, it’s claimed the Calibre 101 is one of the brand’s most recognisable designs.
Fit for a Queen, the white gold timepiece is set with baguette diamonds.
It’s so small that its 98 minuscule parts weight just one gram.
Who is Meghan Markle? Quick profile
Meghan Markle was born Rachel Meghan Markle, on August 4, 1981 to parents Doria Ragland and father Thomas Markle.
Her father was previously married to Roslyn Loveless and Meghan has two elder half sibling – sister Samantha Markle and brother Thomas Markle Junior.
Meghan’s first television appearance in the USA was in an episode of the medical drama General Hospital in 2002.
She later moved on to roles in CSI, Without a Trace and Castle along with bit parts in Hollywood films including Get Him to the Greek, Remember Me and Horrible Bosses.
Meghan was also a “briefcase girl” on Deal or No Deal – but her most famous role was as Rachel Zane in legal drama Suits, which launched in 2011.
She was written out in the finale of the seventh series when her character got married, which aired in April 2018 – just before she got married herself.
Charity and humanitarian work
Meghan Markle’s career in television has gone hand-in-hand with her support for causes close to her heart.
She wrote about the stigma around menstrual health in an article for Time magazine and was a Global Ambassador for World Vision Canada – with whom she travelled to Rwanda for the charity’s Clean Water Campaign.
And her commitment to gender equality has seen her work with the United Nations – receiving a standing ovation in 2015 for her speech to mark International Women’s Day.
In September 2011, she wed film producer Trevor Engelson, who she began dating in 2004.
But the pair divorced two years later in August 2013, citing irreconcilable difference.
She was in a relationship with celebrity chef Cory Vitiello for almost two years, before they broke it off in 2016 but the two remain good friends.
And in June 2016, she met Prince Harry on a blind date set up by a mutual friend.
Their relationship began in October that year and just over one year later, on November 27, 2017, the pair announced their engagement.
They married on May 19, 2018 at St George’s Chapel in Windsor Castle.
Some have claimed Meghan Markle is the first mixed-race member of the Royal Family.
Historians are still arguing about Queen Charlotte, the wife of King George III.
But Meghan will be the first royal to openly embrace a mixed-race heritage.
She has written about the difficulties of being a biracial actress in Hollywood as she claims she is not black enough for some roles and not white enough for others.
