Bremont MB Viper


To test Bremont’s manufactured movement series, the ENG300, the luxury British watchmaker created a concept test instrument to put it through the most extreme testing environment, equaling 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.

Pushing boundaries to understand the true performance potential of Bremont’s ENG300 movement, the ultimate challenge had to involve putting it through the rigorous schedule of environment testing conditions that Martin-Baker deploys across its suite of fighter ejection seats. This included Live Ejection Testing, Zoom Temperature Climb Testing, Extreme Temperature Endurance, High Altitude Testing and Salt Fog Testing. To this end, Bremont initially developed a functional and minimal casing housing a shock isolating mount that could be fixed to the cockpit ‘dashboard’ of a Martin-Baker live ejection ‘simulator’. The test instrument was then developed further with the addition of forged carbon fibre lugs so that it could be affixed to an ejection manikin. Most importantly, the movement, protected by Bremont’s patented Anti-Shock movement mount,
passed with flying colours and maintained impeccable time.

Developing the concept model into a limited edition piece is an exciting proposition that will undoubtedly appeal to collector’s interested in something unique with real testing credibility behind it. The MB Viper is notably the first model in Bremont’s iconic Martin-Baker range to house an ENG300 movement which is visible through its flat exhibition case back. The 43.5mm matte DLC Grade 5 titanium case employs a protective carbon coating and features an anodised 6082 aluminum case middle. Limited to only 300 pieces, the MB Viper not only showcases a different design direction for Bremont but is a true embodiment and representation of what the brand has achieved in its design, engineering, and manufacture.

The self-winding ENG352 calibre boasts a 65-hour power reserve with silicon escape wheel, free sprung hairspring with inertia weight timed balance and KIF shock protection. The movement features rhodium plated bridges with a gold-plated automatic bridge and is encased by Bremont’s trusted rubberised Anti-Shock mount that was developed back in 2009 when the brand first started working with Martin-Baker.

The vibrant orange anodised aluminum case middle is secured with 4 corner Torx® screws and encircles the highly legible white dial with a seconds track. Hours are marked on the dial ring with green emission Super-LumiNova® along with the tips of the chevron-decorated hands whose pattern nods to the signature ejection pull handles seen on fighter ejection seats. This particular feature was actually inspired by some of the very early unreleased MB prototype designs and unlike all other MB models, the MB Viper features a different seconds hand, mimicking that which was used on the test instrument. The tactile matte black lugs, which taper towards the screw down crown, have pockets machined into the rear of them to further reduce weight. Completing the look, the MB Viper comes with two canvas straps, one orange and one black.
Bremont Co-Founder Nick English comments: “When Martin-Baker first approached us in Bremont’s very early days, it wasn’t a branding exercise, it was with a vision of creating the definitive aviation watch.

The testing that they could offer was something previously untried or tested in this industry, it was entirely unparalleled. It’s truly remarkable what these mechanical timepieces can actually withstand. For me it really is the ultimate pilot’s watch and it’s exciting to still be testing the boundaries of the possible with such an innovative and technically excellent British business at the centre of aeronautical and military engineering.

We’re incredibly proud of what we’ve created together, and interestingly, much of the Bremont MB Viper testing was carried out in conjunction with the Martin-Baker Mk18 seat in the Korean KFX Fighter ejection test programme. The Mk18 seat can also be found in other fighter aircraft like the F-16 ‘Viper’. This new
limited edition is pioneering for Bremont with its use of the ENG352 movement, and it’s a timepiece we are incredibly proud of. It really is tested beyond endurance.”

Dating back to 2009, Bremont’s partnership with Martin-Baker truly gave birth to a new generation of pilot’s watch, the Bremont MB. The MB Collection remains to this day the only mechanical timepieces to have undergone and withstood the rigours of live ejection seat launches. Martin-Baker, the British aviation
company responsible for supplying over 70% of the western world’s Air Forces with fighter ejection seat technology, is at the very pinnacle of British engineering and innovation; the now iconic Bremont MB range has redefined the aviation watch world. Never has a mechanical watch gone through such extensive testing.

Andrew Martin, Business Development Director and grandson of Sir James Martin, Co-Founder of Martin-Baker, comments: “This is a relationship which has continued to flourish for more than 15 years. It’s a relationship built on a shared passion for engineering excellence and British innovation. I simply cannot think of another timepiece that has been subjected to this such a draconian testing schedule and pass with flying colours. It is truly exciting what can now be achieved in this country in horology. We all have a lot to be proud of.”

Bremont is an award-winning British luxury watch brand, manufacturing mechanical watches in Henley-on- Thames, England. Bremont is making considerable investment with its UK watch making and manufacturing
and in 2021 opened The Bremont Manufacturing & Technology Centre, a new state-of-the-art 35,000 sq ft purpose-built mechanical watch manufacturing centre enabling the full machining and manufacturing of Bremont’s watches. Co-Founded by brothers Nick & Giles English in 2002, Bremont has made a substantial impact on the watch making industry in a very short period of time.

The brand remains true to its original principles of: aviation and military, British engineering and adventure. As well as manufacturing watches for some of the most exclusive military squadrons around the world, Bremont continues to play an influential role in revitalising the British watch industry, the birthplace of numerous timekeeping innovations still used today. The brand is now in the top handful of chronometer producers in the world. 


With facilities spanning the globe, Martin-Baker has established an extensive range of unique, specialist engineering capabilities. They ensure that all Martin-Baker products are of the highest quality and reliability and will always perform as designed – first time, every time. Past and continued success has defined the
iconic British company as the number one choice for over 88 air forces throughout the world, fitted to over 80 aircraft types. The equipment may represent a crew member’s last chance to survive and there can be no
compromise. Every facet of the safety system must work perfectly to safeguard a precious life. Furthermore, aircrew members must reach the ground uninjured, especially in a hostile environment, if they are to have the best possible chance of survival. This understanding is reinforced by 70 years of experience dating back to the first live ejection test in 1946 and the first life saved in 1949. So, it comes as no surprise that Martin-Baker is the only company worldwide able to offer a fully integrated escape system that satisfies the very latest in pilot operational capability and safety standards. To date, Martin-Baker has saved 7,650 aircrew lives for more than 93 Air Forces.
