QUICK ANSWER
Mechanical refers to a type of watch movement powered by a mainspring that must be wound periodically, using gears and springs to measure time.

Mechanical watches are powered entirely by a wound mainspring, using gears, springs, and an escapement to measure time without any electronics or battery. Quartz watches use an electronic circuit with a quartz crystal oscillator for timekeeping. Mechanical watches require regular winding and servicing but are valued for their craftsmanship and heritage.
Yes, mechanical watches require servicing every 5-10 years depending on the manufacturer's recommendation. Service involves disassembling the movement, cleaning all parts ultrasonically, replacing worn components, re-lubricating pivot points and escapement, and regulating for accuracy. Neglecting service leads to increased wear and eventual movement failure.
Yes, generally. A standard mechanical watch achieves ±10-30 seconds per day. A COSC-certified mechanical chronometer achieves ±4-6 seconds per day. Standard quartz achieves ±15 seconds per month. Despite lower accuracy, mechanical watches are valued for their craftsmanship, longevity, and the tactile connection they provide.
