3 year warranty
Bremont focuses purely on beautifully made mechanical movements and every watch in our core collection has passed each of the rigorous precision tests necessary for the ISO 3159 chronometer designation. Every movement is finished to the highest levels of craftsmanship and all are guaranteed to within -4 and +6 seconds per day. For this reason Bremont is one of the few watch makers to offer at least a 3-year warranty on every timepiece.

Proudly made in the UK
Great Britain has a wonderful history when it comes to watch making and has probably been the home to more advances in horology than any other nation. Bremont is determined to play a pivotal role in the reinvigoration of this industry on British shores. Every Bremont is hand built and tested before leaving the Henley-on-Thames workshop.
Description
The Supermarine 500m marks a bold new chapter in Bremont’s professional dive watch collection. Crafted in 904L stainless steel, the 43mm case features a slimmer, more ergonomic profile with enhanced crown and bezel guards for added durability. Designed to withstand the pressures of deep-sea diving, it boasts a 500-metre water resistance rating, a helium escape valve, and a textured black ceramic uni-directional bezel.
The dial introduces a striking new wave-pattern design, inspired by the ocean’s surface. Applied Super-LumiNova® indexes and sword hands ensure exceptional legibility in low light, while a domed sapphire crystal enhances clarity and adds a refined finish. Powered by the automatic BB64 movement with a 56-hour power reserve, the Supermarine 500m offers uncompromising performance beneath the surface.
Available on Bremont’s newly engineered quick-release Supermarine bracelet – with micro-adjustment and polished-satin infinity links – or a high-performance rubber or NATO strap, this is a rugged yet refined dive watch made for those who take it further.

Engineered for Extremes
With a 500-metre water resistance rating, helium escape valve, and reinforced 904L steel case, the Supermarine 500m is built to perform in the harshest environments – above or below the surface.
Inspired by the Ocean’s Surface
The black dial features a new 3D wave pattern, capturing the movement and texture of the sea. Paired with a gloss finish and crisp detailing, it adds depth and character to the watch while reinforcing its connection to the water it was built to master.
Bold Legibility
Designed for maximum clarity in challenging environments, the Supermarine 500m features applied indexes and sword hands filled with latest generation Super-LumiNova®. Whether diving at depth or navigating low light, the bold, high-contrast layout ensures instant readability.
