Ultimatrix Watch — Ben 10 Ultimate Alien
Our Ultimatrix watch replicates the most advanced Omnitrix variant from Ben 10: Ultimate Alien. This transformation device features evolved alien modes, voice-activated evolution sequences, and the distinctive hourglass dial that defines the Ultimate Alien era.
The Ultimatrix introduced evolved alien forms that surpassed the original ten transformations. Our watch reproduces this upgrade through a two-stage activation system — press the dial once to select your base alien, then hold the evolution button for three seconds to trigger the ultimate sequence.
Display technology & dial mechanics
The green hourglass dial is the Ultimatrix’s visual signature. We’ve engineered ours with dual-layer transparency — a frosted outer lens diffuses the LED array beneath, creating the soft glow seen in the animated series. The matrix doesn’t just light up; it animates in three phases during transformation sequences.
Under the dial sits a spring-loaded pop-up core. Press the center button to release it — the core rises 8mm above the watch face and locks into place with an audible click. This mechanical detail mirrors the moment Ben activated ultimate mode before selecting his evolved form.
Fit, comfort & durability specs
Our silicone band uses a pin-and-tuck closure system with six adjustment holes. The strap tapers from 25mm at the case to 20mm at the buckle, distributing pressure evenly across your wrist. Medical-grade silicone stays flexible in temperatures from -20°C to 60°C, so the watch remains comfortable whether you’re outdoors in winter or at a summer convention.
The case measures 52mm across and 18mm thick — substantial enough to feel like the powerful artifact from the show, but light enough (78 grams with batteries) for all-day wear. We’ve reinforced the bezel with a raised lip that protects the dial from direct impacts.

Common questions about your Ultimatrix watch
Yes, the watch stores sound profiles and LED sequences for all ten ultimate evolutions featured in Ben 10: Ultimate Alien. Rotate through the roster using the side selector button — the display shows each alien’s glyph as you cycle. Ultimate Humungousaur, Ultimate Echo Echo, Ultimate Swampfire, and seven additional forms are pre-loaded and ready to activate.
Press the dial once to select your base alien form. The hourglass matrix will pulse green to confirm selection. Then press and hold the evolution button on the right side of the case for three seconds. The matrix will flash amber and play the evolution sound effect as the ultimate form activates. Release the button when you hear the confirmation tone.
The adjustable silicone band fits wrists from 5.5 inches to 8 inches in circumference. Six adjustment holes spaced 8mm apart let you fine-tune the fit. The pin-and-tuck closure system stays secure during active movement but releases easily when you need to remove the watch.
Battery replacement is tool-free. The compartment on the back of the case uses a coin-slot cover — insert a quarter or similar coin into the slot, turn counterclockwise 90 degrees, and lift the cover off. Replace both AAA batteries simultaneously to maintain consistent power delivery. Alkaline batteries provide approximately 40 hours of active use.
The case is splash-resistant but not waterproof. It will handle incidental water exposure like handwashing or light rain, but do not submerge the watch or wear it in the shower. Water intrusion can damage the LED module and void the warranty. Clean the silicone band with a damp cloth and mild soap, keeping the electronics module dry.
The built-in speaker produces transformation sounds at approximately 75 decibels — loud enough to hear clearly in a quiet room, but not overwhelming in public spaces. Volume is fixed and cannot be adjusted. The speaker grille is positioned on the underside of the case to project sound away from your wrist.
The Ultimatrix introduced evolved alien forms and a two-stage activation system not present in the original Omnitrix. Visually, the Ultimatrix has a green evolution matrix, a pop-up core mechanism, and raised control buttons. The original Omnitrix uses a simpler single-press activation and lacks the evolution mode entirely. Both watches are screen-accurate to their respective series.
