This fifth iteration is the last of five special editions being released to celebrate the occasion

It's been a special year for Swiss watchmaker Tag Heuer. After reviving the Autavia collection that was launched as one of the brand’s main collections earlier this year, Tag Heuer is also celebrating the 50th anniversary of its illustrious Monaco watch. The brand has just released a new limited edition of the iconic timepiece.

When it debuted in 1969, the watch was the first to have a waterproof square case, as well as the world's first automatic chronograph. 

This highly anticipated model is the last of a series that Tag Heuer has released over the last year, following the "1969-1979", a 1970s-inspired model released during the Monaco Formula 1 Grand Prix; the "1979-1989", inspired by the next decade and debuting during the 24 Hours of Le Mans; the "1989-1999," representing the 1990s and unveiled at the Formula E NYC; and the "1999-2009" edition, released in Tokyo at a special event.

The brand took to Shanghai to present its latest edition, and christened the "2009-2019" edition to the public.

The brand's ambassadors, model-actress Cara Delevingne and singer Li Yifeng, were present at the Chinese event, along with the president of the LVMH watch division and CEO of Tag Heuer Stéphane Bianchi.

The watch has a simple, subdued look, featuring a black perforated calfskin leather wristband with a black lining and gray stitching. The matte sandblasted stainless-steel case contains a charcoal dial complete with black gold-plated silver hands and toned-down red accents for a touch of colour.

The Monaco's polished chronograph pushers remain on the right side of the watch, which is one of the features that have made the watch stand out since its 1969 debut. The new "2009-2019" edition is limited to 169 pieces.

As part of the 50th anniversary celebrations of the Monaco, Tag Heuer has also created the one-of-a-kind Monaco Piece d’Art. This restored and decorated version of an original 1969 model of the iconic timepiece will be submitted to Phillips in New York for the Game Changers watch auction, set to take place on December 10. Proceeds from the auction will be donated to the US charity United Way of New York City.
