The Aviation series by Ollech & Wajs are made up of New Old Stock parts of one of the biggest and best watchmaker of yesteryear, Leon Breitling.
The Aviation 34017 uses the legendary Valjoux Calibre 7736 mechanical handwind movement which is modified into a 24 hours movemet. The parts are made using NOS Breitling parts from the 70s. That is why it has a close resemblance to the old school Breitling.
The Aviation 34017 has a black dial with vintaged lume. It is a true 24 hours watch. The slider rule computing dial and bezel allows users to calculate speed, distance and even do mathematical calculations. An instruction booklet is included.
The New Old Stock stainless steel case is finished in a mixture of high polished and satin brushed. And ready to be strapped onto your wrist with the genuine calf leather strap.
Watch comes in the Aviation watch box with slider rule operations booklet.
