The Bremont MB is the ultimate British aviation watch, made in partnership with Martin-Baker. Three models are available: the MBI, MBII, and MBIII. Only those who have ejected using an MB ejection seat can get the MBI, which stands out with its red aluminum barrel. The watch is tough, with a Faraday cage and anti-shock case mount to protect the movement from magnets and bumps. It's been put through the same tests as the seats themselves to ensure durability, including shocks, vibrations, extreme temperatures, and salt-fog exposure.
