Timex expands its Swiss-made watch lineup with new GMT and Marine variants

Timex has refreshed its premium Atelier collection with new colourways for the GMT24 M1a and Marine M1a. The latest additions include a Pepsi-style GMT watch and a deep-blue automatic diver, each available with either a stainless steel bracelet or an NBR synthetic rubber strap.

As detailed in a new official blog post, the updated GMT24 M1a introduces a red-and-blue 24-hour scale surrounding a polished black enamel dial. A contrasting red GMT hand tracks a second time zone, while a date window positioned beside the 3 o’clock marker adds everyday practicality.

The watch retains its 40 mm skeletonised stainless steel case, which is protected by a curved glass-box sapphire crystal with triple-layer anti-reflective coating. Inside is the Swiss-made Landeron 24 GMT automatic movement, offering a 40-hour power reserve. An exhibition caseback lets you view the movement, and it's rated to 100 meters.

Two configurations are available. The TW6A20600 costs $1,450 and comes with a stainless steel bracelet featuring self-adjustable links, a butterfly deployant clasp and tool-free quick-release spring bars. The TW6A20700 swaps the bracelet for a black NBR rubber strap and costs $1,350.

Meanwhile, the Atelier Marine M1a receives a new deep-blue colourway. Its polished blue enamel dial features silver-tone hands and applied hour markers filled with Swiss LumiNova. The 41 mm stainless steel case features a skeletonised construction, a black IP-coated middle case, and a unidirectional rotating bezel with a blue ceramic insert.

The Swiss-made Catena SA100 automatic movement powers the watch, operating at 28,800 vibrations per hour with 29 jewels and a 36-hour power reserve. Other features include an exhibition caseback, screw-down crown and 200-meter water resistance.

The new Marine M1a is offered in two configurations: the stainless steel bracelet-equipped TW6A20400 for $1,050 and the TW6A20500 with a matching blue NBR rubber strap for $950. All references are available through Timex’s US store.
