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.

Mechanical Automatic Movement

Automatic watches have no battery. Instead, these "self winding" movements use the natural movement of your wrist as a power source.

Mechanical Automatic

Powered by You

Close-up of a mechanical watch movement on a black background

A mechanical automatic movement winds itself using the natural motion of your wrist — a rotor inside spins as you move, storing energy in a mainspring. This spring slowly releases power through a precise series of gears and an escapement, driving the hands in a smooth, sweeping motion. It’s a self-sustaining engine, no battery required. When worn daily, it stays powered continuously — keeping perfect time without needing to be reset.

Titanium Case

Thanks to titanium's excellent strength-to-weight ratio, titanium cases are extremely durable yet incredibly lightweight on the wrist.

Our Mid-Century Icon

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.

Smooth as the ‘60s

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.
