Charlie Paris has given the Concordia GMT the kind of update that matters in daily wear, not just on a spec sheet.
The French brand’s travel-ready diver keeps its rugged 300-metre case and second-time-zone functionality, but gains fresh dial treatments, a revised layout and a move to the Seiko NH34 automatic GMT calibre.
The result is a more approachable Concordia GMT, both visually and financially.

At a glance
- Charlie Paris has updated the Concordia GMT with five dial options and revised dial furniture.
- The watch keeps a 300-metre stainless steel dive case with a GMT hand, 24-hour flange and rotating dive bezel.
- Pricing now starts at EUR 645 on a strap and EUR 695 on the steel bracelet.
A travel diver with a cleaner face
The Concordia GMT remains built around a practical idea, pairing a serious dive-watch case with a second-time-zone display for travel or remote work.
The new version measures 40.5mm across and 11.75mm thick without the crystal, with a 47.5mm lug-to-lug span that keeps it in versatile everyday territory.
In steel, the case combines brushed and polished surfaces, a screw-down crown and a sapphire display back.

Water resistance is rated to 300 metres, which gives the Concordia GMT more credibility than many watches that simply borrow dive-watch styling.
The unidirectional bezel uses an anodised aluminium insert with a 60-minute scale and a luminous pip at 12 o’clock.
Above the dial is a double-domed sapphire crystal with anti-reflective coating, adding a more considered touch to the watch’s profile.

Five dial choices and a revised GMT layout
The most visible change is the dial selection, which now spans five distinct personalities.
Tundra uses a textured snow-white dial, Antarctic Blue gets a lightly sandblasted blue finish and Black keeps the watch at its most traditional.
Burgundy brings a vertically brushed smoked red tone with a sandy finish, while Sage uses a vertically smoked green dial with a lightly brushed surface.

Charlie Paris has also revised the hour markers, moving to an all-circular marker layout that gives the dial a more consistent rhythm.
The date sits at 3 o’clock, and the 24-hour scale is positioned on a two-tone flange around the dial rather than on the bezel.
That flange changes with each version, from black and white on Tundra to blue and white on Antarctic Blue, black and mint green on Black, black and burgundy on Burgundy, and dark green with mint green on Sage.

The local-time hands and indexes use Super-LumiNova with green luminescence, while the GMT indications glow blue.
The Seiko NH34 changes the equation
Inside the updated Concordia GMT is the TMI Seiko NH34, an automatic GMT movement that has become a familiar choice for accessible travel watches.
It runs at 21,600 vibrations per hour, uses 24 jewels and offers a 41-hour power reserve.

The GMT setup is the office-style arrangement, with an independently adjustable central 24-hour hand.
That makes it especially useful for tracking a second time zone from home, while frequent flyers may still prefer a traveller-style local jumping hour hand.
The shift from the earlier Swiss Soprod C125 to the Japanese NH34 is central to the watch’s new positioning.

The previous Concordia GMT started at EUR 1,195 on nylon and EUR 1,245 on steel, while the updated watch begins at EUR 645 on a strap and EUR 695 on the bracelet.
Straps, bracelet and everyday usability
The Concordia GMT is offered on a stainless steel bracelet, with nylon, leather and rubber strap options also part of the setup.
A tool-free interchangeable system makes the watch easier to adapt, whether it’s being worn as a desk GMT, a weekend diver or a travel watch.

The 20mm lug width also helps, opening the door to a broad range of aftermarket straps for owners who like to change the feel of a watch without changing the watch itself.
