Product Description
The Altitude MB Meteor 'Felix the Cat' brings together Bremont's aviation heritage with the unmistakable mischievous spirit of one of the world’s most enduring icons. Closely associated with U.S. Navy aviation squadrons, Felix the Cat has long symbolised courage, good luck and fearless adventure in the skies. Limited to just 500 pieces worldwide and engineered to withstand the extreme testing of Martin-Baker ejection seats, this unique watch celebrates a legacy built on precision, durability, and character.
The 42mm Trip-Tick case is crafted from Grade 2 titanium and finished in tactical stealth black DLC, with a knurled PVD titanium barrel and matching crowns. The stealth black dial features applied numerals and indexes filled with high-grade white Super-LumiNova® for maximum clarity, while Felix the Cat appears directly on the dial, cheekily running away with the number 6. Bright yellow accents – inspired by real-world flight safety markings – bring contrast and energy, including the iconic looped ‘ejection’ pull-handle seconds hand, a signature of our MB watches.
The bi-directional inner bezel is operated via our Roto-Click mechanism using the crown at 4 o’clock, delivering the precise, tactile action expected from the MB series. Inside, our BB14 automatic movement offers a 68-hour power reserve and is suspended within a shock-absorbing mount with anti-magnetic shielding.
Turn the watch over to reveal an open case-back with Felix-inspired decoration and the movement’s gunmetal grey finishing with Geneva Stripes.
Limited to 500 pieces worldwide.
