Aerospace-grade titanium, 3D-printed to the gram. 500 made, no more.

Some products are designed to be noticed. This one is designed to be forgotten, in the best possible way. At 28,9 grams, engo3 Titanium is built to sit on your face with the imperceptible presence of a well-balanced aircraft at altitude. You stop noticing it. That was the entire point of building it.

Why titanium, why 3D-printed

Most eyewear is cast, molded, or assembled from parts. engo3 Titanium is grown. The frame is 3D-printed in aerospace-grade titanium, built up layer by layer rather than poured into a mold. That process leaves a visible grain on the surface, a record of exactly how the frame came into existence. It is not a flaw to be polished away. It is the design.

Aerospace-grade titanium exists because industries that cannot afford failure, aircraft, spacecraft, high-performance structures, need a material with an exceptional strength-to-weight ratio and tolerances measured to the gram. We asked what happens when that same standard is applied to something you wear on your face for four hours at mile 20. The answer is engo3 Titanium.

Every gram, a decision

Weight is the enemy of everything this product stands for. Every gram added is a gram your neck carries for the length of a marathon, a gram of drag, a gram of distraction. So every gram in engo3 Titanium had to earn its place.

The result is 28.9 grams total. Less than a few sheets of paper. Less than nothing once you forget it's there, somewhere around mile three. Nothing about this frame exists by default. Everything exists because it has a reason to.

The signal, not the screen

Underneath the titanium is the full engo3 system: a color HUD, red-to-green zones for heart rate, pace, and power, 40+ customizable data fields, and sync with 81+ Garmin devices and Apple Watch. Structured workouts pull straight from your Garmin sessions and run live on the display, intervals and zone targets included.

What makes it different is how the data arrives. Live, with zero latency, traveling from device to eye the way an impulse travels down a nerve. Not a glance. Not a screen you check. A signal you receive. Wired in before the gun even goes off.

The frame runs 24+ hours on a charge, carries an IP55 rating for sweat and water resistance, and adjusts its own display brightness through an ambient light sensor. Solar and photochromic lens options cover everything from a dawn shakeout to a dusk finish. It is, underneath the titanium, still the same serious tool. Just carried differently.

Five hundred, no more

engo3 Titanium is limited to 500 frames worldwide. Not as a marketing device, but as a consequence of what it is: a small-batch object, grown one layer at a time, that was never going to exist at scale.

This is not a product for everyone. It is for the runner who understands that at the edge of a PR, every gram is a decision, every signal is a competitive advantage, and some objects are worth owning for a lifetime.

Signal. Weight. Nothing else.

engo3 Titanium opens for pre-launch on September 30 and launches October 15. Three hundred units, worldwide, while they last.
