Davosa Watch Aviator Quartz Chronograph Silver 16249915. The Davosa Aviator Quartz comes in two different versions: as a 3 hand timepiece or with a chronograph function, driven by tried and tested Swiss made quartz movements. The chronograph distinguishes itself as a true pilots watch thanks to its fly back function: pressing the pusher stops the current time measurement and the hand flies back to zero; on releasing the pusher a new stopwatch process begins. This saves you vital seconds that can prove decisive when flying: a definite advantage of the fly back function as opposed to a conventional chronograph stopwatch function.
