How do I wind a 1950s mechanical watch?

Gently rotate the crown clockwise between your thumb and forefinger until you feel resistance. Stop immediately to avoid damaging the mainspring. For automatic models, wearing the piece provides daily winding through natural wrist movement.

Are these watches waterproof?

Mid-century watches lack modern rubber gaskets and screw-down seals. Exposure to moisture or humidity can easily damage the dial and rust the delicate internal steel components. Keep these timepieces away from water, rain, and hand-washing entirely.

How can I tell the difference between manual and automatic?

Manual wind watches require you to turn the crown daily to store power in the mainspring. If you try to wind an automatic watch endlessly, you will feel a slipping clutch rather than a hard stop. Automatic models also tend to have slightly thicker case backs to house the internal oscillating rotor.

What is a triple calendar watch?

A triple calendar movement displays the day of the week, the month, and the date alongside standard hours and minutes. These apertures and pointers require mechanical gearing to track the changing months. More complex variations within this group also incorporate a moonphase display showing the lunar cycle.
