Charlie Paris Concordia GMT Dive Watch
Starting from 645 €The Charlie Paris Concordia GMT is a dual time zone dive watch, designed and assembled in Paris by an independent house founded in 2014. Descended from a model created for a polar expedition, it combines 300 metres of water resistance, a unidirectional rotating bezel and a fourth hand paired with a two-tone day/night 24-hour chapter ring. Its 40.5 mm 316L steel case, domed sapphire crystal and screwed sapphire caseback give it the look of a genuine contemporary toolwatch, understated and robust. Offered in five dial colours and with numerous tool-free interchangeable straps, it is aimed at travellers, recreational divers and enthusiasts of French tool watches at a measured price.
Charlie Paris Concordia GMT dive watch
Charlie Paris presents itself as the house of Horlogerie Nouvelle. Founded in 2014, it built its model on direct sales, with no middleman, with a design office and assembly workshop based in the heart of Paris, backed by two boutiques on rue Saint-André-des-Arts and rue Sainte-Croix-de-la-Bretonnerie. The brand's pitch comes down to one simple idea: offer durable timepieces, in 316L steel and sapphire crystal, powered by Swiss and Japanese movements, at what it calls a fair price.
The Concordia holds a special place in this catalogue. It was developed in 2018 to meet the requirements of adventurer Matthieu Tordeur's Antarctic expedition, a roughly 1,150-kilometre unsupported crossing completed in 51 days in temperatures as low as -37 degrees. From that origin, the collection retained a toolwatch vocation designed for harsh environments, water resistant to 300 metres and legible in darkness.
The GMT version appeared in 2023, with the addition of a fourth hand and a chapter ring graduated over 24 hours allowing a second time zone to be tracked. The current generation, revised and repositioned on price, adopts a Japanese calibre and widens the palette to five dials. It is aimed as much at the recreational diver as at the traveller who wants to keep an eye on the time back home, without giving up a watch that is comfortable to wear every day.

The Parisian toolwatch Concordia GMT
The Concordia GMT follows in the line of versatile tool watches, able to move from a wetsuit to the office without missing a beat. Its 316L steel case measures 40.5 mm in diameter for a lug-to-lug length of 47.5 mm, a contained size that makes it easy to wear every day. The alternation of polished and brushed surfaces animates the case sides and plays with light, while the unidirectional rotating bezel with an anodised aluminium insert echoes the classic codes of the diver, with its hour scale and luminous marker at 12 o'clock. The slightly brushed black dial favours immediate legibility. The hour markers and hands are treated with Super-LumiNova®, as is the 24-hour chapter ring, the latter using a distinct tone to separate day and night ranges.
Charlie Paris has even differentiated the colours of the luminescent emission: green for local time, blue for the second time zone hand, which avoids any confusion when reading the watch in the dark. Assembled in Paris, the watch has a clearly functional orientation. The 3 mm anti-reflective domed sapphire crystal protects the display while keeping distortion at the edges under control, and the screwed sapphire caseback allows the house's own oscillating weight to be observed. The whole remains understated, with no decorative excess, true to the spirit of an instrument born to accompany a polar expedition.
Five dials and interchangeable straps
The current GMT line comes in five dial colours. The slightly brushed black dial is the most neutral version, the Antarctic Blue recalls the model's polar origin, the Bordeaux and Sage both use a vertical sunburst effect, while the Tundra offers a textured white 'snow' dial, the most visually striking of the series. Each version keeps exactly the same technical architecture: only the dial's tone and finish change, along with the range of straps on offer. On the fastening side, the Concordia GMT plays the card of modularity.
The 20 mm straps can be swapped without any tools, allowing you to move from a Milanese mesh bracelet to rubber or nylon in a few seconds. The catalogue also includes a three or five link steel bracelet, priced a little higher, along with leathers and rubbers in various tones depending on the colour chosen. All configurations receive a Charlie Paris branded pin buckle. This flexibility explains the price range, from €645 to €695 depending on the strap chosen. Above all, it reflects an intention: to make this GMT diver a single watch adaptable to several uses, from a summer dive to a professional trip between two time zones, without needing several watches on the wrist.
Charlie Paris Concordia GMT dive watch: dual time zone and 300 metres
The Concordia GMT combines a 40.5 mm 316L steel case, a unidirectional rotating bezel with an anodised aluminium insert and 300 metres of water resistance guaranteed by a screw-down crown fitted with a red safety marker. Its Japanese automatic TMI/Seiko NH34 calibre displays hours, minutes, seconds, date and an independent second time zone, with 41 hours of power reserve. The anti-reflective domed sapphire crystal and screwed sapphire caseback complete the construction. Hour markers, hands and the 24-hour chapter ring are treated with Super-LumiNova®, with green luminescence for local time and blue for the GMT. Five dials and numerous tool-free interchangeable 20 mm straps are offered.
Movement
The watch is powered by the TMI/Seiko NH34 calibre, a Japanese mechanical automatic movement that handles hours, minutes, seconds, date and an independent second time zone. It has 24 jewels and beats at 21,600 vibrations per hour, a proven rate known for its robustness and ease of servicing. The 41-hour power reserve allows the watch to rest for a full night without winding. This technical choice marks a shift from the previous generation of the Concordia GMT, which was powered by a Swiss calibre.
Diameter and materials
The 316L steel case measures 40.5 mm in diameter for a length of 47.5 mm and a thickness of 11.75 mm, rising to 13.5 mm crystal included. Its surfaces alternate between polished and brushed finishes. The unidirectional rotating bezel features a graduated anodised aluminium insert, with a luminous marker at 12 o'clock. The anti-reflective domed sapphire crystal reaches 3 mm with a 1.5 mm dome. Five dials exist: brushed black, sunburst blue, bordeaux and sage, and textured white 'snow'.
Water resistance
The Concordia GMT claims 300 m / 30 ATM water resistance, a level that unquestionably places it in the dive watch category. This performance rests on a screw-down crown, fitted with a red safety marker that visually signals correct tightening, and on a screwed sapphire caseback revealing the house's own oscillating weight. The unidirectional bezel allows an immersion time to be tracked, and the Super-LumiNova® hour markers and hands ensure legibility at depth as well as at night.
Accessories
Each watch is delivered in a Charlie case, along with an instruction manual and a warranty card. The choice of strap is particularly wide: three or five link steel, Milanese mesh, leather, nylon or rubber, in colours that vary depending on the dial colour chosen. All are 20 mm wide and fit without any tools, allowing quick changes depending on use. The Charlie Paris branded pin buckle equips all the configurations on offer.
Warranty
Charlie Paris applies a two-year warranty from the date of purchase on the Concordia GMT. This warranty covers manufacturing defects exclusively, excluding any other damage. It comes alongside the brand's commercial policy, which delivers each watch in a case along with the instruction manual and the warranty card needed to assert one's rights. This standard cover matches the usual practices of French watchmaking sold direct, with no middleman or third-party distributor.
