You would be forgiven for doing a double-take on that last sentence. Everyone knows that the 7750 family uses stamped steel cam plates to start, stop, and reset the chronograph mechanism not the exotic system of levers that defines the term column wheel. But its true! Over the last decade, the lowly 7750 has been modified to include a column wheel for haute horology companies like Panerai, Hublot, Longines, and Omega.
