Avontic Case Series for Apple Watch Ultra 49mm · Series 11 / 10 46mm
The Ultra has met its match.
Perfected.
Your Apple Watch took years of engineering to create. It deserves more than a generic case. TitaniumGuard 360 Ultra was built to do one thing exceptionally well — protect every millimetre of the watch you wear every day, without compromising the premium look and feel you expect.
The math is simple.
An Apple Watch Ultra screen repair can be expensive. A scratched bezel may not be easy to undo. TitaniumGuard 360 Ultra costs a fraction of the watch it helps protect — and guards what is already on your wrist.
The reality
The desk corner you brush past. The doorframe you misjudge. The barbell loaded with 45-pound plates. The seat belt buckle. The car door handle. The kitchen counter. Every single day, the most exposed surface on your body makes contact with edges, surfaces, and impacts you barely register.
Then one morning, you catch the light at the right angle — and notice the hairline scratch along the bezel. Or the scuff on the corner. Or the dent. By then, it already happened.
TitaniumGuard 360 Ultra exists for one reason: to help protect your watch before that moment happens.
The solution
Zero Compromise.
A single precision-formed shell wraps the watch perimeter — frame, bezel, corners, and display edge. Every Apple Watch control remains easy to use. The Digital Crown turns. The Action Button presses. The sensors read. Nothing changes about how your watch works. Everything changes about how protected it feels.
Crafted to the millimetre
01 · 360° Architecture
A single shell protects the frame, bezel corners, and display edge in one continuous structure. The places that usually take the most contact are addressed first.
02 · Metal-Inspired Finish
Designed to read as part of the watch. The finish complements titanium and stainless steel looks without feeling bulky or out of place.
03 · Full Control Access
Digital Crown, Action Button, side button, microphone, speaker, sensors, and charging access remain easy to use.
04 · Five-Second Install
No tools. No tutorial videos. Align it, press it on, and go. Designed for fast everyday use.
05 · Four Curated Finishes
Black, Gun Grey, Silver, and Titanium. Each finish is selected to pair cleanly with premium Apple Watch case colors and bands.
06 · Precision Model Variants
Two distinct variants — Ultra 49mm and Series 11/10 46mm. Each is formed for its specific case geometry.
The four finishes
Titanium
The purist choice.
For owners who want the case to blend into the watch it protects.
Black
The stealth statement.
Pairs beautifully with black sport, ocean, and alpine-style bands for a strong monochrome profile.
Gun Grey
The tactical middle.
Darker than silver and softer than black, ideal for slate-tone and rugged setups.
Silver
The polished classic.
A clean, refined choice for a brighter premium Apple Watch look.
Where it performs
At the Office
Laptop edges, boardroom tables, desk corners, and doorframes — the ordinary contact points that can mark your watch over time.
In the Gym
Barbells, dumbbells, pull-up bars, treadmill rails, and spin bike frames — equipment your watch should not touch, but sometimes does.
On the Move
Airport trays, overhead bins, bag straps, car doors, and travel days that expose your watch to more contact than usual.
Everyday Life
Kitchen counters, bathroom sinks, keys, bedside tables, and the constant little moments that make protection worth having.
The TitaniumGuard difference
This One Protects the Watch.
Most cases focus on the display — the most obvious surface, but not the only area that matters. The bezel, corners, frame, and display edge are all exposed. TitaniumGuard 360 Ultra protects the watch perimeter in a single shell without unnecessary bulk.
Total Coverage
Frame, bezel, corners, and display edge — addressed in one protective shell.
Zero Compromise
Buttons, sensors, charging, and daily functionality remain easy to use.
Instant On
Snaps on quickly with no tools required.
