The Bremont Boeing Model 247 represents the debut chronograph in the collaboration, named after the first Boeing twin-engine commercial aircraft. The two ‘twin-like’ sub-dials tastefully reflect this inspiration. The Model 247 Stainless Steel is built from exceptionally tough Custom 465® Stainless Steel. The hardened case incorporates screw down crowns and chrono pushers, together with an exhibition sapphire crystal case back.
