Brothers Nick and Giles English describe Bremont's 'Supermarine Type 300' as "amphibious" - its name is an aviation reference (based on the 1930s aircraft company whose first-ever 'Spitfire Prototype' was built prior to WWII and became one of Britain's most legendary airplanes) but its technology is optimised for scuba diving. This timepiece is housed in hard-wearing stainless steel and powered by a Modified Swiss-made calibre 11 ½" BE-92AE automatic movement. Its three-piece Trip-Tick® construction ensures water resistance at up to 300m, an impressive technical feat that doesn't compromise its slim profile - there's just 13mm between the sapphire crystal lens and case back.
