How do I wind an automatic watch?

An automatic watch winds itself through the natural motion of your arm while worn during the day. If the watch has stopped entirely, give the crown a few manual turns to jump-start the movement before wearing it. Unlike manual-wind models, automatic calibres feature a slipping bridle on the mainspring to prevent over-winding. Regular daily wear keeps the internal rotor moving and maintains a continuous power reserve.

What is a bumper movement?

A bumper movement is an early type of automatic winding mechanism used during the 1940s and 1950s. Instead of spinning in a full circle, the weighted rotor swings back and forth against internal springs. Wearers can often feel a gentle tap or knock on the wrist when the oscillating weight hits the bumper springs. This distinct tactile feedback identifies the vintage mechanical era of the watch.

Are these watches waterproof?

Vintage dress watches were generally not built for deep water immersion or swimming. Gaskets, crystals, and crown seals degrade over decades, losing their original resistance to moisture. It is safest to keep these wristwatches away from water, heavy rain, and high humidity. Regular servicing by a watchmaker can renew seals, but vintage pieces remain unsuited for modern aquatic use.

How do I read a vintage watch reference number?

Reference numbers stamped inside the case back or on the exterior identify the specific model, case material, and production design. Manufacturers used these codes to catalogue their inventory and match replacement parts. Comparing the reference number against historical factory archives helps confirm the production era and original configuration of the watch. Not every mid-century model bears an exterior case number, as many makers placed them on the interior surface instead.
