With professional divers in mind, Bremont increased the size of the original Supermarine case to 45mm and re-engineered it to withstand further depths of 2000m/6560ft. The design of the Supermarine was built using Bremont’s unique Trip-Tick three-piece case construction. As with the previous model, extensive testing in the UK by Bremont has led to the design and construction of the ‘Anti-Shock’ COSC certified movement mount to help protect it against large shocks. It is also housed inside an Anti-Magnetic faraday cage to protect the balance, balance spring and escapement from any effects of magnetisation.
