A Fresh Take on Retro-Futurism
The Marlin® Jet Titanium Automatic builds on our retro-futuristic icon with a lightweight titanium case and a GMT function that lets you track a second time zone. Keeping line with the space-age style of the Marlin Jet, it's topped with a domed crystal made from scratch-resistant Hesalite—a refined form of acrylic favored for its clarity and ease of maintenance.

Keeping line with the space-age style of the Marlin Jet, it's topped with a domed crystal made from scratch-resistant Hesalite—a refined form of acrylic favored for its clarity and ease of maintenance. This unique crystal covers the entire top surface of the watch case, enveloping the grooved bezel bearing the Marlin name and bringing captivating depth to the watch's retro-futuristic appearance. It blends seamlessly into the flat case sides, leaving only the lugs exposed. The case sides smoothly transition to a screwed-on exhibition case back that mirrors the crystal’s domed contour, enhancing the watch’s streamlined profile. You’ll find a concentric circle pattern in two key locations on this timepiece: beneath the dome on the inner bezel and on the case back. The grey concave dial showcases a mix of printed and applied indices, as well as a date window beside 3 o’clock. Completing the look is an eco-friendly natural leather strap with quick-release spring bars.

Hesalite Acrylic Crystal
A Hesalite acrylic crystal offers excellent shatter resistance and can be easily polished to remove light marks over time.
Acrylic Crystal
Highly impact-resistant
Acrylic lens are a specialised form of plastic akin to Plexiglass and were commonly used in early to mid-20th century watches. It is a softer material that can be more prone to scratches but conversely is very shatter-resistant. Given its softness any scratches though can be buffed out. Acrylic lens are synonymous with vintage-inspired timepieces and thus can be found on our Marlin and Q Timex collections.

The original Marlin watches first stepped into the spotlight in the 1950s and matured into a centerpiece of Timex’s broader collection in the 1960s. Today's Marlin collection draws inspiration from that era, pulling both from Timex archives and '60s culture more generally.
Marlin is pure 1960s cool, delivering substance and style in equal measure, with unwavering swagger. Timeless and sophisticated, it's a watch that captures the best of the past while continuing to push Timex’s legacy of style, disruption, and quality into the future.

"Overall, I like this watch very much. Is is light on the wrist, but doesn't feel cheap. The styling is very attractive and the band is comfortable. The only issues I have with it are 1) seems like the power reserve isn't great, and 2) the box and packaging was cheap for a watch in this price range, and 3) no manual came with the watch. For a watch at this price point, I expected better packaging."

Great watch! I only wish
"Great watch! I only wish it was 100mts Water resistance. It doesn't matter if it was more expensive, is a beautiful watch , great dial but useless for my daily use , As the way I wear my watches, Cooking, Swimming, just being worry less about them , A true companion and at 50 mts it is not that, it's more like a Toy Watch. At the time I bought it didn't realize it was 50mts."

Q&A
Can you buy a rubber strap to go with it or a bracelet?
Hello Mab! The Marlin® Jet Titanium Automatic GMT 40mm Leather Strap Watch features a quick-release strap, so you can purchase a separate replacement strap if you would like to change the look or style of the watch. We recommend choosing a strap with the correct lug width and compatible ends for the best fit. We hope this helps you explore different strap options for your watch!
Is this a “travel type” GMT (as appears to a “caller”
Hello James! Great question, and we’re glad you asked. The Marlin® Jet Titanium Automatic GMT 40mm Leather Strap Watch is an office GMT, sometimes referred to as a “caller GMT.” This means the GMT hand is adjusted independently, making it especially useful for tracking a second time zone when traveling or coordinating internationally.
When will this watch be available for sale or viewing at local Timex ADs?
Hello William! The Marlin® Jet Titanium Automatic GMT 40mm Leather Strap Watch is currently a Timex.com exclusive. It is not available for sale or viewing through local Timex authorized dealers at this time. We recommend checking Timex.com for the latest availability and updates. Thank you for your interest in this special model!
Are both the hour hand and GMT hand 24h?
Hi Luiso! Thank you for your question. The Marlin® Jet Titanium Automatic GMT 40mm Leather Strap Watch has a 24-hour GMT hand, while the main hour hand tracks standard 12-hour time. We hope this helps clarify how the two hands work together to display a second time zone.
