Parisian Precision for Global Exploration: Charlie Paris Concordia GMT Watch

When independent French watchmaker Charlie Paris introduced the Concordia back in 2018, it was not merely to create another handsome daily diver.

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.

Polar-Tested Craftsmanship & 300m Aquatic Resilience

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.
