How do I wind a vintage manual watch?

Turn the crown gently clockwise between your thumb and forefinger until you feel resistance. Stop immediately to avoid damaging the mainspring. Most vintage watches require winding once a day, ideally at the same time each morning to maintain steady tension.

Are these watches water resistant?

Vintage timepieces lack modern rubber gaskets and screw-down systems designed for aquatic activities. Even models marked Seamaster should stay dry to protect the delicate internal movement. Accidental splashes happen, but swimming or showering with a vintage piece risks severe moisture damage to the dial and calibre.

What is a bumper automatic movement?

A bumper automatic utilises an oscillating weight that swings through a limited arc rather than spinning in a complete circle. Springs at either end bounce the rotor back into motion. This early self-winding technology was common in the 1940s and 1950s before full rotor systems became standard industry practice.

How should I store my vintage watch?

Keep the timepiece in a dry, temperature-controlled environment away from direct sunlight and strong magnetic fields. Dedicated watch boxes or padded storage cases provide adequate protection against dust and impact. If the watch remains unwound for extended periods, running the movement periodically prevents internal lubricants from settling.
