The 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 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.

Having proven incredibly popular since launch, introducing the S300 White into the Supermarine range is the perfect counterpart to the other darker dial variants within the line. The contrasting blue ceramic bezel sets off the lighter dial beautifully and matches the blue indexes and blue rubber strap. In keeping with the existing models, the S300 White features a unidirectional bezel, Super-LumiNova® hands and the 40mm steel case is decorated with the silhouette of the original Supermarine aircraft on the back.
