"I love the style and design of the watch, the quality is also top notch. I'm very impressed by the Swiss movement only falling behind a few seconds each day with mine. If Timex can consistently deliver this type of quality and performance I will be a long time customer."

I love the look and
"I love the look and feel of this watch, the size is great. And it was a wonderful watch for 1.5 weeks. At that point I noticed a rattle when I moved my arm while driving to wind the watch. I then saw the time was off. When I got parked I saw that the hour and GMT hand had collapsed onto eachother. I cant mail it back and dont want to I like this watch alot, but untill I know that your luxury tool watches can handle just normal wear I cant recommend anyone buy them. That being said I have several of your 40 to 70 dollar watches and all have been through the same for longer and all are working just fine. I will be going to a watch shop for repair and I will resume wearing this watch once fixed."

Q&A
Are you guys planning on releasing some kind of atelier watch with a lighter White / Champagne Color Dial?
Hi Max! Thanks so much for the suggestion! While we don’t have any updates to share at the moment, we’ll be sure to keep it in mind for future collections. We always appreciate hearing what our customers would love to see!
Is it planned to release a 18mm NBR Synthetic Rubber Strap separately ? It is a bit frustating having to chose between the two options... I went for the steel bracelet but I would have loved to have both.
Hi Samuel! Thank you for your interest in the Timex Atelier GMT Première M1a 38mm Swiss Made Automatic Stainless Steel Bracelet. While we don’t have any updates to share at the moment, we’ll be sure to keep it in mind for future collections. We always appreciate hearing what our customers would love to see!
Hello It's a great watch, but a little to big for me at 38mm. Do you plan on releasing a smaller (ex. 35mm) variant? Kind regards,
Hi Antoni! Thanks so much for the suggestion! While we don’t have any updates to share at the moment, we’ll be sure to keep it in mind for future collections. We always appreciate hearing what our customers would love to see!
Will a larger version be availble soon, or is it in development?

Is this a traveller GMT?
Hello Paul! The Timex Atelier GMT Première M1a is an office GMT rather than a traveller GMT. This means the GMT hand is designed to track a second time zone while the local hour hand remains independently set in the conventional way. I hope this helps clarify how the GMT function works.
