Estate Habring² SS Chrono COS Watch "Prototype"

A 42mm stainless steel case with white lacquered dial and lovely blued steel hands and indices from Habring². It features their patented Crown Operated System (COS) for the operation of the chronograph... and ingenious system patented by the Habrings to start, stop and reset the chronograph by turning the crown rather than the conventional pusher system.

Complete with Box and Papers, officially listed on the paperwork as "Prototype".

As always, this watch comes with a 1 year warranty from Passion Fine Jewelry.
