CS Factory Watch — mechanical watches | csfactorywatch.com
The choice comes down to a swinging balance wheel versus a vibrating quartz fork, and to how much winding and service you want to live with.
A quartz watch uses a piezoelectric quartz tuning fork, usually at 32,768 Hz, and an integrated circuit divides that frequency to one pulse per second. There is no mainspring and no escapement, so there is nothing to wind.
A mechanical watch regulates a balance wheel and hairspring. Its rate is affected by temperature, position and lubrication, so a well-regulated movement typically varies by a second or two a day.

Quartz watches are more stable over a month, usually within a few seconds, but they need a battery every two to five years. Mechanical watches need winding and a clean and lubrication every five to seven years.
Neither is strictly better. Quartz suits low-maintenance accuracy; mechanical suits an owner who accepts winding and periodic service as part of use.
