Beautiful Ollech and Wajs pilot slide rule Aviation chronograph.  A true classic in aviation design, and if it looks similar to a Breitling, that's because it's made up from Breitling parts.  After Breitling went into liquidation Mr. Wajs bought the liquidation stock of the former Leon Breitling Company in 1980.  This included most assets including watch parts, designs and machinery.  From these parts Mr. Wajs created the Aviation range.  The Aviation watches are identical in terms of size, case, dial, hands and movements as the original Breitling's of before 1980.
