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 case back, 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

"Nice solid construction and attention to detail. My first and possibly last GMT"
"Fast and furious". . . in a
""Fast and furious". . . in a very much good way! ;-) The timepiece: no comments! I'm a watch enthusiast/lover and I've bought aprox 10 watches during 2025 (from USD500 to USD10000). Among all the watches (I'm not going to mention the brands) the Atelier GMT24 was / is my favorite! And BTW, customer service: spot on!!! Thanks much guys! You're awsome!"
I Love the watch! It
"I Love the watch! It is so nice to have a middle range watch from Timex for my collection. I have always loved the designs of Timex watches. It’s beautiful to see every time I look at it. It is super comfortable on my wrist and a pleasure to own."
Ordered this watch from Timex
"Ordered this watch from Timex directly and was shipped and delivered very fast. The watch is beautiful and well made. However I tested it using TickIQ app and it was losing or gaining more than 50 seconds daily which is not acceptable for a watch in this price range and with Swiss movement. Therefore I returned and was promptly refunded. Timex customer service is the best. The refund and return was a very smooth process"
What a fantastic purchase for
"What a fantastic purchase for the price. Such a beautiful finish. The skeleton case is eye catching. The dial is beautifully balanced. My only criticism is the shape of the crown guard and the size of the crown. Well, that does you something to work on for the M2a or the M1b."
4 stars because it was
"4 stars because it was a pricey item. Did like the link adjustment w/o any tool, great feature."
Q&A
- What is the lug to lug measurement for the Timex Atelier GMT24 M1a
- Hi Jason! The lug-to-lug distance of Timex Atelier GMT24 M1a 40mm Swiss Made Automatic Stainless Steel Bracelet is approximately 48 mm, with an internal wrist sitting of about 42 mm. We hope that helps you get a better sense of how it’ll wear on your wrist.
- You state the mid-case is plated steel. So, would it be true to say it is carbon steel, not stainless steel, and subject to rusting/corrosion if the mid-case coating were ever scratched through the skeletonized outer case? What is the coating? Galvanized? Rust-Oleum paint? Blueing?
- Hello Tom! Thank you for your question about the Timex Atelier GMT24 M1a 40mm Swiss Made Automatic Stainless Steel Bracelet. To clarify, the case material is indeed stainless steel, and it is finished with Ionic Plating. This provides both durability and a refined appearance while maintaining resistance to corrosion.
