Avontic Apple Watch Sport Armor Collection
Stainless Steel Case + Rubber Sport Band System for Apple Watch
Designed for Apple Watch Ultra & Large-Case Series Models
Sport Band Control.
AeroGuard Steel Sport Pro upgrades your Apple Watch with a stainless steel protective case and reinforced rubber sport band pairing. Built for customers who want a more rugged, athletic, and complete Apple Watch setup, this system adds outer case coverage, sport-ready comfort, stainless steel styling, and a bold everyday wrist presence.
A standard Apple Watch band changes the strap. AeroGuard Steel Sport Pro changes the entire setup by pairing a stainless steel protective case with a reinforced rubber sport band for a stronger, more athletic, more complete Apple Watch look.
What makes AeroGuard Steel Sport Pro different
Most Apple Watch upgrades stop at the band. AeroGuard Steel Sport Pro goes further by combining a stainless steel protective case with a rubber sport band, creating a more cohesive, more rugged, and more athletic Apple Watch setup.
The stainless steel case helps cover the outer watch body from common scratches, scuffs, bumps, and daily surface contact, while the sport band provides a flexible feel for training days, travel, commuting, and everyday wear.
Why upgrade to a case and sport band system?
A sport band alone keeps your watch functional, but the watch case still looks unchanged. AeroGuard Steel Sport Pro upgrades both the strap and the watch exterior for a more rugged, coordinated, sport-armor appearance.

Reinforced Rubber Sport Band
The rubber sport band gives the system a flexible, athletic feel for workouts, outdoor routines, travel, and daily movement.
