How do automatic watches work?

Automatic watches contain a weighted internal rotor that spins as the wearer moves their arm. This kinetic energy winds the mainspring, keeping the watch powered without manual winding. Most pieces from this era require regular wear or a watch winder to maintain their power reserve and continue keeping accurate time.

What is a bumper automatic movement?

A bumper automatic is an earlier style of self-winding movement developed before full-rotor systems became standard. The weight inside bounces back and forth against small springs to wind the mainspring. Wearers can often feel or hear a gentle tap on their wrist as the bumper weight moves inside the case.

How should I care for a vintage dress watch?

Vintage dress watches require gentle handling, protection from strong magnetic fields, and avoidance of moisture unless the case has been professionally sealed and tested. Leather straps should be kept dry and replaced as they age. Routine servicing by a qualified horologist ensures the internal metal gears and automatic mechanisms remain lubricated and accurate.

How can I tell the period of a watch?

The period can often be identified through case styles, dial typography, hallmark stamps on gold cases, and movement serial numbers. Mid-century designs lean towards clean lines, minimalist markers, and distinct lugs. Matching the movement calibre and case reference numbers helps confirm the exact decade of manufacture.
