The Engineering Heritage of Bremont

Bremont‘s journey began when brothers Nick and Giles English channelled their passion for aviation and mechanical engineering into creating a distinctively British luxury watch brand. Following the tragic death of their father in a vintage aircraft accident, the brothers established Bremont with a mission to craft exceptional timepieces that would honour his memory and their shared love of flying.

Unlike many Swiss watchmakers focused on tradition alone, Bremont brings an engineer’s approach to horology, emphasising extreme durability testing and innovative construction methods. Establishing their manufacturing facility in Henley-on-Thames, Bremont has played a pivotal role in reviving British watchmaking expertise, leveraging both traditional craftsmanship and modern technology to create timepieces that are as robust as they are refined.

Key milestones in Bremont’s impressive history include:

  • 2002: Nick and Giles English found Bremont in the UK
  • 2007: Introduction of the ALT1-C, Bremont’s first chronograph model
  • 2009: Launch of the Martin-Baker collaboration, creating watches tested to withstand ejection seat forces
  • 2010: Introduction of the Supermarine, Bremont’s first dive watch collection
  • 2012: Release of the Victory watch containing actual materials from HMS Victory
  • 2014: Opening of Bremont’s watchmaking facility in Henley-on-Thames
  • 2016: Introduction of the America’s Cup collection
  • 2019: Launch of the Armed Forces collection with official MOD approval
  • 2021: Opening of The Wing, Bremont’s new UK manufacturing and technology centre
  • 2023: Introduction of the Longitude collection with in-house movement

Throughout its history, Bremont has maintained a commitment to technical innovation and authentic storytelling that has earned it a unique position in the luxury watch market. Unlike brands that focus primarily on decorative finishing or design for design’s sake, Bremont has developed technically superior timepieces that offer genuine utility and exceptional durability, all manifested by the company’s aviation-inspired aesthetic.


Iconic Bremont Collections

ALT1: Aviation Chronographs

Bremont’s core chronograph collection takes its name from “Altitude” and represents the brand’s aviation heritage in its purest form. These pilot’s watches combine exceptional legibility with precise timing functions and robust construction suitable for real-world flying conditions.

The ALT1-C, Bremont’s original chronograph, features a beautifully balanced dial with two subdials and distinctive applied hour markers. The ALT1-Z adds GMT functionality for pilots crossing time zones, while the ALT1-P offers a more utilitarian aesthetic for professional aviators. All share Bremont’s commitment to precision, with COSC-certified movements ensuring chronometer-level accuracy.

Today, the ALT1 family encompasses several distinct lines, including the classic ALT1-C, the ALT1-WT world timer, and special editions developed for military squadrons. All maintain the essential characteristics that define a proper pilot’s chronograph: excellent legibility, precise timing functions, and robust construction capable of withstanding the rigours of actual flight.

Supermarine: Professional Dive Watches

Named after the British aircraft company that produced the legendary Spitfire, the Supermarine collection demonstrates Bremont’s ability to apply its aviation-inspired engineering principles to professional dive watches. These robust timepieces combine exceptional water resistance with distinctive design elements that set them apart from conventional dive watches.

The collection began with the S500, offering 500m water resistance and anti-magnetic protection via a soft iron Faraday cage. The line expanded to include the S2000, which extends water resistance to an impressive 2000m while maintaining wearable proportions. Special editions like the Endurance, tested in Arctic conditions, and the Waterman, developed with ocean conservationists, demonstrate Bremont’s commitment to real-world testing in extreme environments.

Martin-Baker Collection: Ejection Seat Tested

Perhaps Bremont’s most distinctive collaboration, the Martin-Baker series honours the British company responsible for manufacturing ejection seats that have saved over 7,500 aircrew lives. These watches undergo the same rigorous testing as the ejection seats themselves, including extreme temperature variation, vibration, and explosive decompression.

The collection features distinctive design elements inspired by ejection seat components, including the yellow and black loop used on the seats’ firing handles. Certain models are exclusively available to pilots who have actually ejected using Martin-Baker seats, creating a unique connection between the timepiece and genuine aviation experience.

Limited Editions: Material Innovation

Bremont has distinguished itself through limited editions that incorporate genuine historical materials, creating watches with tangible connections to significant events, aircraft, and vessels:

  • HMS Victory: Containing original oak and copper from Lord Nelson’s flagship
  • Wright Flyer: Incorporating actual fabric from the Wright Brothers’ first aeroplane
  • Concorde: Featuring aluminium from the supersonic airliner
  • Hawking: Containing materials from Stephen Hawking’s personal effects
  • Williams Racing: Incorporating carbon fibre from Formula 1 race cars

These special editions represent Bremont’s innovative approach to storytelling through watchmaking, creating timepieces that are not merely inspired by history but contain authentic pieces of it.


Bremont’s Technical Innovations

Trip-Tick® Case Construction

Bremont’s patented three-piece case design represents a significant innovation in watch durability. Unlike conventional two-piece cases, the Trip-Tick® construction features a hardened central barrel (available in various colours) sandwiched between a solid case back and bezel/crystal assembly.

This central case barrel undergoes a special surface-hardening treatment that increases its hardness to 2000 Vickers, approximately five times harder than typical stainless steel. This exceptional hardness, combined with the three-part construction, provides superior shock protection while creating Bremont’s distinctive aesthetic profile.

B-EBE2000 Hardening Technology

Bremont’s proprietary case-hardening process, known as B-EBE2000, goes beyond surface treatments used by other manufacturers. This diffusion-based technique creates a hardened layer that penetrates deep into the metal, resulting in exceptional scratch and impact resistance without affecting the material’s inherent properties.

The process was developed specifically for Bremont’s aviation-inspired watches, drawing on technologies used in aircraft components. The resulting cases offer durability far exceeding industry standards, ideal for the active lifestyles of their clientele.

Anti-Shock Movement Mounts

Inspired by anti-shock systems used in aircraft instruments, Bremont’s movement mounting technology provides exceptional protection against impacts and vibration. The movement is secured within a flexible ring that absorbs shocks that would damage conventional watches, allowing Bremont timepieces to withstand forces that would typically cause timing errors or component failure.

This system is particularly evident in the Martin-Baker collection, where watches must withstand the extreme forces generated during ejection seat testing. However, all Bremont models benefit from this enhanced shock protection, contributing to their reputation for exceptional durability.

Special Materials

Bremont pioneers the use of innovative materials in watchmaking, often incorporating elements with genuine historical significance:

  • Boeing Aviation-Grade Titanium: Used in collaboration with Boeing for exceptional strength-to-weight ratio
  • HMS Victory Oak: Wood salvaged from Lord Nelson’s flagship
  • Concorde Aluminium: Metal from the iconic supersonic airliner
  • P-51 Aircraft Aluminium: Material from historic WWII fighters

These materials provide not only distinctive aesthetic properties but often contribute to the watches’ technical performance through enhanced hardness, lightness, or corrosion resistance.


Frequently Asked Questions About Pre-Owned Bremont Watches

What makes Bremont watches unique?

Bremont watches are distinguished by their British engineering approach that prioritises technical excellence and durability. Unlike many Swiss luxury brands that emphasise decorative finishing or extreme complications, Bremont creates timepieces with a clear purpose, whether that’s aviation, diving, or military use. The company’s innovative Trip-Tick® case construction, extreme testing protocols, and incorporation of historical materials have fostered a distinctive mindset that blends British engineering precision with aviation heritage, resulting in watches that appeal particularly to those who value substantive engineering and authentic storytelling.

Are Bremont watches a good investment?

As a relatively young brand (founded in 2002), Bremont occupies an interesting position in the collector market. While not yet achieving the investment status of century-old manufactures, certain Bremont models have demonstrated good value retention, particularly limited editions with historical materials, military-exclusive editions, and core models like early examples of the ALT1-C and Supermarine. The brand’s focus on engineering excellence rather than passing trends tends to create timepieces with enduring appeal. However, as with all luxury watches, condition, rarity, and provenance significantly impact potential investment value.

How often should I service my Bremont watch?

Bremont recommends servicing mechanical watches every 3-5 years to maintain optimal performance. For professional models with enhanced water resistance like the Supermarine, annual water resistance testing is advisable if the watch is regularly exposed to water. Despite their robust construction, regular servicing ensures the longevity of these precisely engineered timepieces and preserves their value. Bremont maintains excellent service support for all their models, including discontinued pieces.

What is the Trip-Tick® case construction?

The Trip-Tick® case is Bremont’s patented three-piece case design featuring a hardened central barrel that achieves a surface hardness of 2000 Vickers (compared to about 400 Vickers for standard stainless steel). This hardening process penetrates deep into the metal, making the case exceptionally resistant to scratches and impacts. The three-part construction also provides superior shock protection for the movement and allows for distinctive design elements like coloured middle barrels, contributing to both the watches’ durability and aesthetic distinctiveness.

How can I tell if a pre-owned Bremont is authentic?

Authentic Bremont watches feature precise engineering, high-quality finishing, and specific details that vary by model and production period. Key authentication points include: the distinctive three-piece Trip-Tick® case construction, precisely integrated crown guards, COSC chronometer certification on the movement, and correctly positioned serial numbers consistent with the model and production year. For limited editions, verify appropriate numbering and certificates of authenticity. Given Bremont’s technical excellence, any signs of poor finishing or imprecise assembly are red flags. At MVS Watches, all our Bremont timepieces undergo rigorous authentication by specialists familiar with the brand’s specific characteristics.
