Manchester City boss Pep Guardiola was seen flaunting one of the rarest watches in the world that is worth around £1.1million during his side's trip to Real Madrid on Tuesday evening.

The Spaniard is known for his stylish outfits and sharp fashion sense, often patrolling up and down the touchline in polo necks and designer brands throughout his years as a manager. 

And after arriving in Madrid - one of the biggest fashion capital cities on the planet - Guardiola turned up the style as he decided to wear one of the most exclusive watches money can buy. 

The watch Guardiola wore during the Champions League clash at the Bernabeu is designed by high-end brand Richard Mille - specifically created for tennis superstar Rafael Nadal.

It's official name is Calibre RM27-01, which has a manual winding tourbillon movement with an open design showing the gears and hands inside.

There are only 50 versions of the watch worldwide and it is the lighest mechanical watch ever

The watch also features yellow lines and dots to resemble the minutes and hours, with a red tip on the hands indicating the time. 

The 27-01 edition has broken the world record for the lightest mechanical watch of all time, weighing at 18.83 grams, including the strap, using grade five titanium, aluminum and lithium to construct it. 

It is so rare that there are only 50 versions in the world, with Guardiola and Nadal two of the lucky recipients - so perhaps its no surprise that the watch would set you back over £1m. 

The watch uses four braided steel tension cables attached to the baseplate, protecting the movement of the hands while keeping its lightweight design. Richard Mille say the process in designing these cables is an 'extremely delicate operation'.

Richard Mille calls the invention of the watch 'a triumph of engineering and technology' and 'one of the most innovative architectural constructions of recent years' that has been crucial to Nadal's performances at big tournaments thanks to its comfort when wearing it.

Guardiola was present in the Spanish capital to oversee an exciting game between Madrid and City in the first leg of the Champions League quarter-finals - which finished 3-3. 

Bernardo Silva opened the scoring after just two minutes from a free kick before Ruben Dias' own goal levelled the scores. Rodrygo then turned the game on its head before Phil Foden's superb shot from outside the box found its way into the top corner.

Josko Gvardiol then smashed in a stunner of his own to make it 3-2 to City before Federico Valverde had the last laugh with an incredible volley to ensure the spoils were shared ahead of the second leg.
