Charlie Paris Watch: Concordia GMT Automatic Tundra

Charlie Paris: the Concordia GMT Tundra, a French automatic GMT tool watch water-resistant to 300 meters

The Charlie Paris Concordia GMT Tundra is an automatic watch designed for both travel and demanding sports use. Its new generation adopts a 40.5 mm 316L stainless steel case, a textured white dial, and a true GMT function allowing you to track a second time zone over 24 hours. Designed and assembled in Paris, the Charlie Concordia GMT Tundra also retains the 30 ATM / 300-meter water resistance that characterizes the Concordia collection.

The Charlie Concordia GMT Tundra measures 47.5 mm lug-to-lug and 11.75 mm thick excluding the crystal, for a total of 13.5 mm including the crystal. Its white dial is protected by a 3 mm domed anti-reflective sapphire crystal, while the unidirectional rotating bezel features an anodized aluminum insert with an hourly scale and a luminescent marker at 12 o'clock. The screw-down crown of the Concordia GMT Tundra features a red safety marker that allows for a visual check that it is properly screwed down.

At the heart of the Charlie Concordia GMT Tundra now lies the Seiko NH34, a 24-jewel Japanese automatic mechanical caliber operating at 21,600 vibrations per hour / 3 Hz and offering approximately 41 hours of power reserve. It features manual winding, hacking seconds, a date function, and a central GMT hand that can be adjusted independently in one-hour increments. This architecture allows the Concordia GMT White to easily track a distant time zone.

The Charlie Concordia GMT Tundra visually distinguishes between local time and the second time zone using two luminescence colors: green for local time and blue for the GMT function. The screw-down case back features a transparent sapphire crystal allowing you to observe the NH34 movement and its rotor signed by Charlie. The Concordia GMT Tundra is available with a wide choice of 20 mm straps, interchangeable without tools.

About the brand Charlie Paris

Founded in 2014, Charlie Paris designs and assembles its watches in its Parisian workshop. The company develops contemporary French watchmaking, relying on Swiss and Japanese movements and collections designed to combine design, functionality, and daily use.

The Charlie Paris Concordia GMT Tundra is part of a collection born from the Concordia model developed in 2018 to accompany Matthieu Tordeur's expedition to the South Pole. With this new generation, Charlie Paris evolves the Concordia GMT around a more accessible version equipped with the Seiko NH34 caliber and a reworked 40.5 mm case, while retaining the fundamental elements of the collection: 300-meter resistance, high readability, and a tool watch architecture.
