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. Bremont has wanted to create a 40mm dive watch for some time, not necessarily designed to the exact parameters as the S500 and S2000, but certainly embodying Bremont’s engineering DNA and with the capability of reaching at least 300m in dive depth. Every Bremont Supermarine Type 300 is chronometer rated and houses a beautifully finished BE-92AE automatic movement. There will be two variations of the Type 300, and one sister model, the Type 301. Of the two Type 300s, the Type 300/BK has a black dial and ceramic bezel insert, and the Type 300/BL a blue dial and ceramic bezel insert.
