A Dual-Time Machine for the Modern Traveller
The Timex Atelier GMT24 M1a brings clarity and proportion to one of watchmaking’s most enduring functions. Every surface is deliberate, each detail shaped to balance depth and wearability. At its core is the Swiss-made Landeron 24 GMT automatic movement, revealed through an exhibition caseback, with a fourth hand marking time across borders. This is not a jet-age revival. It is time, refined for the traveller’s wrist.Specifications
