Timex Atelier GMT Premiere M1a 40mm TW6A07300

The Timex Atelier GMT Première M1a reinterprets the architectural design of the collection in a more compact 38mm case, maintaining an aesthetic based on clarity, structural precision, and mechanical functionality.

The Swiss-made automatic GMT movement allows for reading two time zones, thanks to the dial with a black enamel surface and a black and green 24-hour ring to distinguish day and night. The skeletonized steel case reveals a central section with an IP gold finish, while the double-domed sapphire crystal and exhibition case back enhance the refinement of the materials.
