Named after the first aircraft built by Boeing, known as the B&W, the Bremont Boeing Model 1 is a unique timepiece that reflects Boeings extensive experience in advanced material research. Manufactured from Custom 465? Stainless Steel, this double vacuum-melted, age-hardenable alloy was developed for the aerospace industry for superior strength, hardness and corrosion resistance. The Model 1 features the unique Bremont Trip-Tick case construction with integrated crown guard. Their beautifully decorated BE-36AE movements are suspended in Boeing blue decorated steel and rubber anti-shock mounts exposed for all to see through the crystal case backs.
