Watchmaker Bremont has unveiled an impressive number of grail timepieces since its 2002 founding. Started by brothers Nick and Giles English, the British maker is best known for its meticulously crafted pilot’s watches equipped with complex mechanics, all assembled within the UK.

After five years in production, the brand debuted its first range of watches in 2007, including the ALT1 and Martin-Baker, and since then has focused on developing and refining its signature Trip-Tick case construction – a three-piece case featuring a case bezel, a separate case middle and the case back.

The Supermarine, a line of tool watches for underwater exploration, is one of the brand’s most popular timepieces, which now welcomes its latest generation, the new Supermarine Full Ceramic. First launched by Bremont in 2010, the Supermarine is the ultimate all-conditions tool watch – robust, reliable and capable of functioning both below and above the waves.

Presented in two variants – a limited-edition “Jungle Green” and a “Tactical Black” core edition – the new 43mm Supermarine Full Ceramic is, as the name suggests, housed in mono-block ceramic, a first for Bremont. This unique finish has been achieved using a precisely shaped mould in which ceramic powder is heated at a temperature of 1,450°C under high pressure to shrink the size of the case by 23 per cent. The resulting case is then sand-blasted to achieve the desired hue. The “Jungle Green” model is kitted out with the addition of a green titanium PVD-treated bezel.

As would be expected from a high-performance tool watch of this calibre, the Supermarine Full Ceramic is suited to even the most unforgiving conditions with a titanium container and helium escape valve. To showcase the rugged nature of this capable wristwear, Aldo Kane, a seasoned adventurer, safety expert and Bremont ambassador, has been testing the new Supermarine Full Ceramic in the field as he explores jungle environments on scientific and research missions.

‘I have probably taken my Bremont to more places on the planet than anyone else and the Supermarine has performed incredibly on my jungle missions this year,’ says Kane, speaking of the Supermarine’s top-tier specs. ‘I first went to the jungle when I was 19 as a Royal Marines Commando being trained in jungle warfare. Over the 28 years since, I have worked in jungles all over the world, from tracking tiger poachers in Southeast Asia to climbing into the canopy in Central Africa. The forest is the great equaliser. It crushes egos, builds resilience and hones a deep connection to the natural world. If you can operate in the jungle, you can operate anywhere.’

Alongside its mono-block ceramic case and ceramic bezel insert, the new-generation Supermarine has been elevated with applied indexes and black gold-plated hour, minute and second hands filled with Blue Emission Super-LumiNova for use in low-light conditions. The dial, meanwhile, has been adorned with a date window at 3 o’clock and Bremont’s “The Wayfinder” logo – all presented on a Nato-style fabric strap, woven on 18th-century jacquard French looms.

‘At Bremont our tool watches are worn by those that endeavour to push themselves to the most extreme environments on earth,’ says Davide Cerrato, Bremont’s CEO. ‘We are constantly striving to evolve and improve the technical performance of our watches. The Supermarine Full Ceramic is a highly technical and qualitative dive watch, demonstrating our passion for perfection.’
