Cristiano Ronaldo invests in an online luxury watch marketplace

Cristiano Ronaldo has continued to explore his passion for luxury watches by investing in the online marketplace Chrono24.

Chrono24 announced that Ronaldo has become a shareholder in the company after buying an undisclosed stake.

The 38-year-old, who now plays for Saudi Arabian side Al-Nassr, posed with the company's co-chief executive and founder Tim Stracke on Instagram.

'Watch lovers all over the world, we have amazing news for you: Cristiano Ronaldo, the football just joined Chrono24 as shareholder,' the company said.

'His passion for timepieces met his business genius and he’s taking both to the next level.

'It’s a big day for us and our community, whose love for watches knows no bounds.'

The company, founded in 2003, claims to feature over 530,000 watches from more than 3,000 dealers.

It is claimed that more than nine million unique visitors visit the website each month.

Ronaldo has reportedly followed Bernard Arnault’s family investment company, Aglae Ventures, General Atlantic, Insight Partners and Sprints Capital in buying stakes in the company.

Ronaldo - who signed a £175m-a-year deal with Al-Nassr- is famed for his array of luxury watches and already has a collection of them worth around £5m, in addition to a £18m fleet of supercars.

From a £1.6million Franck Muller, Van Cleef & Arpels timepiece with 474 white diamonds to a one-of-a-kind Hublot 'Masterpiece' worth at least £800,000, Ronaldo is known for his expensive taste.

Ronaldo was gifted a luxury watch worth £92,000 at the launch of a new collection in May by Jacob and Co.

The watch company released a new collection showcasing the best moments from Ronaldo's career - with his iconic 'Siu' celebration shown on the flip side of the timepiece.
