Bremont Titanium Boeing Watch Model BB247-TI-GMT/DG/BR

Inspired by Boeing’s progressive twin-engined Model 247 airliner from the 1930s, Bremont’s unique chronograph has two sub-dials that reflect the aircraft’s radial engines. Like the Model 1 Ti-GMT timepiece, the case is manufactured from Boeing aviation-grade Ti 6-4 Titanium. The Bremont Trip-Tick case construction incorporates a screw down crown and chrono-pushers. The Model 247 also features an exhibition sapphire crystal case back through which the automatic chronometer movement can be seen. By 1933 aircraft design had moved forward rapidly, with Boeing at the forefront of innovation. The twin-engined Boeing Model 247 was a major advance in passenger air travel. Used by both civilian and military operators, the Model 247 set the standard for basic airline design for the next decade.
