Hublot King Power Tourbillon GMT – First Hublot Tourbillon Watch to Feature a Dual Time Zone Indicator

The King Power TOURBILLON GMT is the first Hublot Tourbillon watch to feature a dual time zone indicator. The two-colour dial is set in the 2 o’clock position to allow the traveller to see the time in the place of his or her choice. The King Power Tourbillon GMT has another special feature at 9 o’clock: its Retrograde Date.

The gold colour of this watch is completely unique. It is the result of a newly developed, rarified alloy made especially for this timepiece. The alloy is known as “King Gold”, and is obtained primarily by adding 5% platinum, distinguishing it from all other currently known alloys and making it all the more precious. The delicacy of its microstructure ensures that the alloy is perfectly stable, which means durable quality and a long-lasting intense red colour. Its enduring, intense red and toughness create a unique aesthetic.
