How do I wind a manual watch?

Turn the crown gently clockwise between your thumb and forefinger until you feel resistance. Stop winding immediately once you feel this tension to avoid damaging the internal spring. Wind the watch around the same time each day to maintain steady timekeeping. Avoid over-winding, as forcing the crown past the stopping point can snap the mainspring.

Are these watches waterproof?

Most vintage watches lack modern waterproof seals and gaskets. Even pieces described as hermetic or military issue should be kept away from water. Keep the watch dry during daily wear, removing it before swimming or bathing. Moisture inside the case can damage the dial and rust the delicate mechanical movement.

How do I care for a leather strap?

Keep the leather strap dry and clean by wiping it periodically with a soft cloth. Avoid exposing the leather to direct sunlight and excessive heat. Remove the watch before strenuous physical activity to prevent sweat from degrading the material. Replacing a worn strap preserves the overall wearability of the timepiece.
