Bremont Supermarine S301



The new Bremont Supermarine Type 300 range responds to a demand for a professional dive watch in a slightly smaller iteration. The watches’ namesake derives from the 1930’s aircraft company, Supermarine, whose first ever Spitfire prototype – the Type 300 – led to one of Britain’s most iconic aircraft. The new 40mm case of the Type 300 is also slimmer being only 13mm from sapphire crystal to case back featuring a uni-directional ceramic rotating bezel.
