MB VIPER LIMITED EDITION
A CONCEPT TEST WATCH COMES TO LIFE
To test Bremont’s manufactured movement series, the ENG300, Bremont created a concept test instrument to put it through the most extreme testing environment, equalling that of fighter ejection seat technology.
Enlisting the support of renowned British aviation company Martin-Baker it would have to be designed, developed and built to endure anything a pilot might and more. The test instrument that was developed captured the imagination of both Bremont and Martin-Baker who have subsequently decided to launch it in its own right, and so was born the Limited Edition MB Viper, a lightweight model crafted from titanium and anodised aluminium.
THE TEST INSTRUMENT
Eager to push boundaries and understand the true performance potential of Bremont’s ENG300 movement, the ultimate challenge had to be to put it through the rigorous schedule of environment testing conditions that Martin-Baker deploys across its suite of fighter ejection seats.
In 2022, Bremont continued its pursuit of the ultimate pilot’s watch by designing an instrument that could house the Bremont manufactured ENG300 movement in order to subject it to these tests.
FORM FOLLOWS FUNCTION
The unique shape of the watch originates from a special mount engineered by Bremont, designed to securely fix the ENG300 Test Instrument in place whilst being subjected to HALT (Highly Accelerated Life Testing) – a number of rigorous tests completed in the laboratory by Martin-Baker. The ENG300 movement signals the first time in 50 years that mechanical movements have been built at scale on British shores. The test instrument housed this movement within its patented anti-shock movement mount, designed to absorb impacts whilst continuing to perform faultlessly.

ZERO/ZERO EJECTION TEST
A zero/zero ejection test is one of the closest representations of a real live ejection. The test manikin, with watch strapped to wrist, is propelled from zero to 120ft in 2 seconds while experiencing forces of up to 15G.
EXTREME TEMPERATURE ENDURANCE
The watch is subjected to Extreme Temperature Testing to ensure it continues to operate in extreme conditions. The watch is held for one day in temperatures as low as -46°C, and then up to 49°C for a further 24 hours.
SALT FOG
The ACDT (Aircraft Carrier Deck Test) simulates the level of salt fog and humidity that an aircraft carrier deck would endure during a 6-month tour. Exposure to salt and then drying for 96 hours tests the watch against corrosion and the binding of moving parts.
ICE BLOCK FREEZE
The watch is fully submerged for over 21 hours and frozen at -5 deg C. This tests the seals of the watch as the ice expands, demonstrating the ability to endure freezing temperatures.
HIGH ALTITUDE
The watch is held in an Altitude Test Chamber to simulate taking it up to 100,000 feet for 60 minutes before being rapidly brought down again.

IF THE MILITARY DEPEND ON THEM, YOU CAN
Bremont has manufactured military watches for over 400 units worldwide and our watches are worn by real pilots. The Bremont MB is a popular choice for these professionals due to its robust nature and the testing that it has endured.
