The Supermarine S500 and S2000 are Bremont divers watches inspired by our aviation principles. Each maintains the Bremont DNA with an anti-magnetic Faraday cage encasing the beautifully finished chronometer-tested BE-36AE movement, as does the patented anti-shock case mount. The S500's 43 mm case can withstand depths of up to 500 metres - although it has been tested far deeper, while the sapphire bezel offers extraordinary luminosity in low light conditions. The 45mm case of the S2000 has been re-engineered to withstand a depth of 2000 metres. Both cases also have an automatic helium escape value for professional diving requirements.
