The Bremont MB was designed to be quite simply the definitive British aviation chronometer. Tested and designed in conjunction with the iconic British aviation company 'Martin-Baker.' The movement is protected by an anti-magnetic Faraday cage and a specifically designed anti-shock case mount. The MB range had to withstand the same rigorous testing as the seats themselves. This includes shock, vibration, temperature extremes, and salt-fog tests amongst others.

The automatic timepiece features a 43mm titanium case and a domed, anti-reflective, scratch resistant sapphire crystal. The metal colored dial has an Arabic numeral index with the date at 3 o’clock. The end of the seconds hand features a black and yellow loop which matches the ejection pull handle. The aluminum barrel has a knurled texture, just like the components from the ejection seats. The watch is delivered on a rubber strap.
