Product Details
At first glance, the Altitude MB Meteor Stealth Grey keeps a low profile: a sleek, strong and sculptural silhouette in ultra-matt Grade 2 titanium. Lightweight and durable, its Stealth Grey finish is designed to absorb light and limit glare. But beneath that monochromatic surface is Bremont's MB series engineering — the trusted build behind our most advanced pilot’s watches. Built to withstand live ejection tests, its movement is protected by anti-magnetic shielding and equipped with a shock-absorbing movement mount.
Look closer: an embossed meteorite-inspired dial, scanned from an actual meteorite for its unique texture; applied indexes infilled with high-contrast Super-LumiNova® for clarity in all conditions; and a yellow “ejection” seconds hand, seen only on the exclusive MBI and inspired by cockpit safety markings.
The next evolution in our legacy of stealth watches is here.
Limited to 400 pieces worldwide.
