LIGHTWEIGHT TRIP-TICK® CASE CONSTRUCTION
The MB Viper is designed to be as light as possible, utilising high-performance, aerospace materials such as aluminium and Grade 5 Titanium.

The Trip-Tick® case design houses the ENG300 movement which is protected by a patented anti-shock movement mount, and has specialised ‘pockets’ on the rear to remove excess weight. Click, to see the large size. ▶ BIG FOTO 
To this end, the
MB Viper features a patented rubberised Anti-Shock
movement mount which protects the
ENG352 calibre movement from
significant shocks and jolts, whilst the
43.5mm matte DLC Grade 5
Titanium case employs a protective carbon coating and an
anti-reflective, scratch resistant sapphire crystal.
DESIGNED FOR OPTIMUM VISIBILITY
Inspired by the original Test Instrument, a distinctive bright orange bezel provides improved visibility, a necessity during the ENG300 Testing Programme should the watch have become dislodged from the manikin during ejection testing and have to be located in a field.

The chevroned hands provide excellent legibility and are typically observed in fighter jet cockpits, highlighting features of importance.
A MOMENTOUS STEP FOR BRITISH WATCHMAKING
In 2021 Bremont released its own ENG300 movement series marking a significant milestone for both the brand and British watchmaking as a whole. A new manufacturing line for machining base components and T0 assembly has been realised at the Bremont Manufacturing & Technology Centre “The Wing” based in Henley-on-Thames, UK.

Bremont has made considerable investment into new machinery, staff and training and the firm’s in-house technical team has re-engineered 80% of the base calibre, including making a number of design improvements, in order to build a proprietary movement to the brand’s unique specification. The
ENG300 signals the first time in
50 years that mechanical movements have been built at scale on
British shores.
POWERED BY A BREMONT MANUFACTURED MOVEMENT
The MB Viper is powered by a Bremont manufactured ENG352 calibre movement which features a 65 hour power reserve and comes with an extended warranty of 5 years upon registration.

A significant amount of expertise, logic and intellectual property has been transferred to
Bremont, together with all relevant design rights especially in relation to parts machining and finishing, tool design and fixtures, and the movement assembly line.

Not only will movement parts, such as main-plates, automatic and balance bridges be manufactured and sub-assembled at
Bremont’s Manufacturing & Technology Centre, but the movement will be fully assembled (down to jewel setting and regulation) at the new facility too. This represents an incredible leap forward for
British watchmaking and this weighty progression marks the first time any UK movement manufacturing at scale has been done in
50 years, since Smiths in
1971.

It is tested using Bremont’s H1 Timing Standard, which is directly comparable to the ISO3159:2009 Chronometer test. Bremont has spent many years working on movement design and engineering including most notably developing new IP in the UK with highly acclaimed movement designer Stephen McDonnell, a project which continues to be progressed for a high complication. It has always been Bremont’s ambition to bring the art of industrial high-end watchmaking back to British shores. In the 1800s, close to half of the world’s clocks and pocket watches were made in this country, as was so much of the horological design and innovation that went into them, and many other timepieces built around the world.

Renowned for beautifully made, yet robust and shock-proof timepieces,
Bremont sought to make improvements wherever there was an opportunity to enhance the toughness of the base calibre. One notable improvement was choosing to utilise a full balance bridge, which supports the balance wheel assembly.
To fine tune the movement’s accuracy, traditional adjustment screws are used on the free sprung balance wheel, a more difficult method of rate adjustment, but also more precise, and links back to early marine chronometry. Further design changes include revisions to the escapement, the automatic winding bridge jewels and a modified wheel bridge amongst others.

The Test Instrument subjected the
ENG300 Series movement to Live Ejection Testing, Zoom Temperature Climb Testing, Extreme Temperature Endurance, High Altitude Testing and Salt Fog Testing.
SUPER-LUMINOVA®
To ensure optimal lighting in the poorest of conditions, green emmission Super-LumiNova® has been applied to the hour markers and infilled within the tips of the hour and minute hands.

The vibrant orange anodised aluminium case middle is secured with 4 corner
Torx® screws and on the dial, hours are marked with 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.
COMPLIMENTARY STRAP
The MB Viper comes with a black canvas strap and a complimentary orange canvas strap, allowing the wearer to alternate their style.

The Bremont H1 Timing Standard not only nods to Bremont’s home in Henley-on-Thames but is also named in homage to Harrison’s first ‘H1’ marine timekeeper that famously sought to solve the problem of measuring longitude out at sea. Historically one of the most prominent observatories for watch testing was the Kew Observatory in England and reinvigorating a British chronometer test is something Bremont has long since been building up to.
