Boeing Model 247 TI-GMT

BB247-TI-GMT

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 available in 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. Focused on both safety and speed, it was the first twin airliner able to fly on one engine only, and the airframe incorporated revolutionary design features like autopilot, control surface trim tabs and de-icing capability. The Model 247 set a new trans-continental speed record, transiting a phenomenal eight hours faster than any previous aeroplane. Passengers could travel non-stop across the US continent for the very first time. Used by both civilian and military operators, the Model 247 set the standard for basic airline design for the next decade.
