The watch was engineered to meet the brutal demands of adventurer Matthieu Tordeur, who wore a prototype during his historic 1,150 km solo trek across Antarctica in temperatures plunging to -37°C and the latest collection marking a return to expeditions in Northern Norway.
Building on that polar-tested pedigree, the Parisian outfit has elevated their flagship tool watch with the Charlie Paris Concordia GMT Watch, creating a refined dual-time companion for modern global travellers.
Starting at €645 or €695 with a steel link bracelet, this 40mm timepiece balances high-spec aquatic durability with sophisticated French design.

Designed and hand-assembled in the heart of Paris, the Concordia GMT strikes a balance between rugged tool-watch aesthetics and urban elegance. The 316L stainless steel case measures a versatile 40mm in diameter with a compact 47.5mm lug-to-lug span and a slim 12.5mm profile.
Featuring an interplay of brushed flanks and polished bevels, the housing sits comfortably flat on the wrist under a neoprene wetsuit or a tailored shirt cuff.
Despite its refined proportions, the Concordia GMT is built for serious aquatic exploration.
Delivering 300 metres (30 ATM) of water resistance, the watch features a screw-down crown equipped with a smart safety feature: a red anodised aluminium ring on the stem that alerts the wearer if the crown is not fully tightened before entering the water.
Swiss Soprod C125 GMT Calibre & Dual-Zone Aesthetics
Beating behind a sapphire exhibition caseback—complete with a custom signed Charlie rotor—is the Japanese automatic movement, TMI/Seiko NH34 calibre.
Operating at a high-beat frequency of 28,800 vibrations per hour (4Hz) across 25 jewels, this mechanical engine features Incabloc shock protection and a 42-hour power reserve.
“Designed and assembled in Paris after surviving a 1,150km solo Antarctic trek, the Charlie Paris Concordia GMT pairs a 300m water-resistant case with a Swiss Soprod GMT engine.”
The dial layout presents a masterclass in spatial harmony and low-light legibility. Framed by a 3mm domed sapphire crystal with anti-reflective coating, the matte black sandblasted dial features an outer 24-hour ring split into crisp white and sky-blue sectors for intuitive day/night tracking across a second time zone.
Faceted 3D hands and hour markers are filled with Grade A Super-LumiNova, offering bright nocturnal illumination, while a date window sits neatly at 6 o’clock.
Tailored Utility & Parisian Heritage
Surrounding the dial is a unidirectional rotating timing bezel with an anodised aluminium insert and a lumed 12 o’clock marker.
Complete with a 20mm tool-free quick-release strap system in durable nylon or leather, the Concordia GMT transforms from a rugged dive tool into a sleek travel watch in seconds.
