Some of the finer points of design that went into the development of the Hadley Rille Escadrille 43 tie the watch into its aviation heritage. The sapphire crystal exhibition caseback provides a focus view of the finishing and quality of the Sellita SW290-1 movement. It is highlighted by a brushed stainless steel pattern representing the blur of a jet turbine which is symbolic of Hadley Rille's aviation roots.
Likewise, the small second hand derives its time scale from John Hadley’s quadrant which he designed in 1730. The spirit of John Hadley’s invention and design are incorporated into the Escadrille 43.
The blue hands on the Escadrille 43 harken to the hardened toughness, fine quality watchmaking and the tool watch adventure spirit of the Hadley Rille name. They also add an eye-catching blue hue when the watch face meets sunlight.
