Alex Hamilton’s thirteenth lesson introduces automatic winding systems, categorizing them into bumper oscillators, Seiko’s “magic lever” ratchet system, and ETA’s modern reverser wheels. He explains the unique mechanical logic of each—such as how reverser wheels alternately lock and unlock to ensure the mainspring winds regardless of the rotor’s direction—and provides specific lubrication protocols for these high-speed components. The tutorial demonstrates advanced techniques like using dip lubricants (Lubeta V105/V106) for sealed ball bearings and offers a “pro tip” for creating a DIY dip solution using isopropyl alcohol and Moebius 9010
