Camilla, Duchess of Cornwall wears a Fitbit - and we've found it at a drop-down price!

Camilla, the Duchess of Cornwall, has previously spoken about her love of walking - so it's only natural that her next step was to start tracking her movement.

The 74-year-old royal has this week been touring the UK counties of Devon and Cornwall with her husband, Prince Charles - and we naturally couldn't help but notice that she's been sporting a trusty fitness tracker throughout.

Judging by it's grey strap and rose-gold casing, Camilla's tracker of choice appears to be the Fitbit Charge 3. 

First released in October 2018, it's a relatively old model - but still has some of the key features you'd expect from the best fitness trackers, including a step counter, activity tracking and 24/7 heart rate monitoring. It's also waterproof up to 50m - great if Camilla decides to take a dip in the Cornish sea.

However, a newer model - the Fitbit Charge 4 - was released in April last year. This model improved on the Charge 3 by adding built-in GPS, which means users no longer have to carry a phone with them in order to track their activity. It was this improvement that led the Charge 4 to top our list of the best Fitbits.

Having spied the tracker on Camilla's royal wrist, we took it upon ourselves to hunt out the best deal on the Charge - and reader, we've come up trumps.

The best price we've found on the Fitbit Charge 3 today is $209.99 in the US and £199.99 in the UK (both at Amazon). However, when we searched for Charge 4 for the drop-down price of $98.95 in the US and £97.99 in the UK (both also at Amazon). Result! Check out these cheap fitness tracker deals below...

It's no real surprise that Camilla has taken to tracking her activity - both the Duchess and Prince Charles are known to be big fans of walking, so especially when they spend time in Scotland. The couple even posted an Instagram pictured on Christmas Day that showed them clutching the walking sticks they use for hiking. 

Last year, Camilla also spoke about Charles's love of walking in an interview with BBC Radio 5, describing him as "like a mountain goat".

“He’ll walk and walk and walk,” she said, adding: "He leaves everybody miles behind.”
