Timex Atelier Pepsi GMT: I like the design more than the reserve
101/120 bezel clicks. Atelier GMT24 M1a Pepsi: design, specifications and sourced price qualifications.

The Timex Atelier Pepsi GMT looks like something I would actually stop to try on. I like the red-and-blue scale, the black dial and the way the case has a bit of structure without turning into a pile of angles. There are plenty of familiar GMT ingredients here, but the sculpted case keeps it from feeling like Timex simply borrowed a bezel and called the job done.
The two executions are TW6A20600 on steel and TW6A20700 on black NBR rubber. Both have the black enamel dial, luminous applied markers, a date at three and a red GMT hand. I would lean toward the bracelet. The broad outer links look appropriate against the case, and I like the continuity of steel around the darker dial.
The side view is part of the appeal
Timex lists a 40 mm diameter, 48.11 mm lug-to-lug measurement and 12.7 mm height. I like the diameter, but the length is worth checking on a wrist instead of assuming that every 40 mm watch fits the same. The glass-box sapphire also adds a visible curve over the dial. Its triple anti-reflective coating is a manufacturer specification, rather than something I have tested under different lighting.
The steel outer case surrounds a gunmetal IP-coated middle section, and the crown screws down. Water resistance is 100 meters. The attachment is 20 mm, with quick-release spring bars, and the steel bracelet uses self-adjustable links and a butterfly clasp. Those are useful practical details, although the photographs don't tell me how fine the fit adjustment will feel over a long day.
The movement is the Swiss Landeron L24 GMT automatic, with 28 jewels and an approximately 40-hour reserve. Timex names the extra 24-hour hand but does not establish its independently adjustable hand in the material I checked, so I am not labeling it a traveler GMT. That is something I would verify before using the function as a reason to buy. I would also want a clear explanation of servicing this caliber.
Fourteen hundred dollars is real competition
The US price is $1,450 on steel or $1,350 on rubber, checked November 7, 2026. At that level I would want to compare the bracelet, setting action and finishing with other GMTs in person. An attractive case gets it onto that comparison list; it doesn't finish the comparison.
The November 5 Timex introduction confirms these exact updates, but October Windup previews mean the first global reveal is unresolved. Stock and delivery remain unverified. I'm giving it 101 out of 120 bezel clicks. I like the complete design enough to keep looking, with the movement's setting behavior and service support at the top of my next-check list.
