The Aristos Automatic Sapphire Watches

A round mechanical watch is a timepiece with a circular case that operates using a mechanical movement, which relies on a mainspring and gear system rather than a battery.

A mechanical watch works by winding a mainspring that stores energy, which is then released through a series of gears and an escapement mechanism to regulate timekeeping.

Most mechanical watches need to be wound daily, although some have longer power reserves and can run for 72 hours or more on a full wind.

Automatic watches wind themselves through the motion of the wearer's wrist, while manual-wind watches require the wearer to wind the crown manually.

To adjust the time, pull out the crown to the appropriate position and turn it clockwise or counterclockwise. Be sure to follow the manufacturer's instructions, as some watches are sensitive to date changes at certain times.

Regular winding, keeping the watch clean and dry, avoiding exposure to magnets, and having it serviced every 3-5 years are key to maintaining a mechanical watch.

Mechanical watches are prized for their craftsmanship, longevity, and the smooth sweeping motion of the second hand. They do not require batteries, unlike quartz watches.

It depends on the watch's water resistance rating. Some mechanical watches are water-resistant and suitable for swimming, while others are not. Always check the specifications before exposing the watch to water.

Mechanical watches are often more expensive due to the intricate craftsmanship, labor-intensive manufacturing process, and higher-quality materials used in their construction.

Automatic watches are generally accurate but may lose or gain a few seconds per day. The accuracy can vary based on the movement and maintenance.
