How do automatic watches work without a battery?

An internal weighted rotor spins as the wearer moves their arm, tightening the mainspring that powers the mechanical gears. This continuous self-winding action keeps the watch running without the need for electricity or batteries.

Are these vintage watches water resistant?

Most vintage pieces from the nineteen-fifties and sixties lack modern gasket seals and should be kept away from water. Accidental splashes can damage the untreated internal movement and stain the leather strap.

How do I wind an automatic watch manually?

The watch can be wound by turning the crown clockwise while it is pushed flush against the side of the case. Doing this periodically adds tension to the mainspring if the watch has not been worn for a day or two.

What does a chronometer certification mean?
