The portable timepiece even paid tribute to Saudi Arabia with its emerald green colour – matching the nation’s flag.

The watch is 18K white gold, 47mm x 15.85mm and is worth £630,000.

But that is just a fraction of the most expensive watch in his collection – a Franck Muller Invisible Baguette Diamonds Imperial Tourbillon worth £1.6million.

Ronaldo, 38, earns a reported £3.3m a week at Al-Nassr so money is no object when it comes to funding his watch habit.

Five months into his Saudi stay the superstar was gifted yet another Saudi-themed Jacob & Co. watch worth £92,000.

The ‘Heart of CR7 Baguette’ watch that was given to the striker features his iconic celebration on the back and is covered with 26 baguette-cut white diamonds on the frame.

In the same month Ronaldo splashed out on Jacob & Co. watch priced at £750,000.

The Portuguese star also became a shareholder of watch selling Chrono24 after buying an undisclosed stake in the company in July.6The Jacob & Co. gift bore a Saudi Arabian themeCredit: Instagram @jacobandco6Ronaldo gifted one of his watches to Francis NgannouCredit: Instagram @cristiano

The company, which is said to be worth around £770m, was founded in 2003 and claims that over nine million people visit the website monthly.

Ronaldo’s watch collection is believed to be worth £5m, so he has plenty to offer as gifts.

That is exactly what he did when he met former UFC champion Francis Ngannou ahead of his fight with Tyson Fury in Riyadh, Saudi Arabia last month.

Ronaldo gave Ngannou a watch worth a reported half a million Saudi riyals or £110,000.
