For sale is a well-preserved WYLER Pump Wind Automatic Watch, powered by "pump-action". This early 1930's watch was one of the first attempts at an automatic winding watch.
"Pump-Action", an innovation by WYLER, comprises of a lift & pin mechanism, which is activated when the watch is worn. A secondary case cover or flap pushes against a pin on the back, thereby winding/powering the movement!
The case is numbered "77", making this one of the earliest Wylers in the world - Definitely a sought-after true vintage timepiece!
