Watches with calendars: Day date watches display the date and day of the week. Full calendar watches display the date, day of the week, and month.
Chronograph watches: Chronographs act as a stopwatch or use a meter to measure elapsed time. Chronographs can also come in split seconds format to measure two time segments simultaneously or consecutively.
Watches with a tachymeter: Tachymeter scales, located around the rim of a watch dial, measure average speed by calculating time and pre-measured distance. They are used along with a chronograph.
Watches with moon-phase indicators: Watches with moon-phase indicators have a display that indicates the phase of the moon with an image on a rotating disk.
Watches with tourbillions: Some mechanical watches have tourbillions, small but very costly mechanisms, which help eliminate potential time errors.
Water resistant watches: Usually described on the dial or back of the case, a watch's water resistance is measured in feet, meters, or atmospheres (ATM). Watches that are water resistant up to 30 meters are splash-proof. Water resistance up to 50 meters indicates that you can wear the watch in the shower. A water resistance rating of 100 meters indicates that you can wear a watch swimming. Watches with a water resistance rating of 200 meters can be worn scuba diving.
Watches with repeaters: Watches with a repeater announce the time through a series of chimes when you press a button.
Telemeter scale watches: Telemeter scales measure the distance between a watch wearer and an object that generates a visible signal and a loud noise (such as a fired cannon or electrical storm).
World time watches: Watches with a world time feature indicate time in all time zones around the world. You can often choose the name of a major city in a certain time zone to see the time in that time zone. |
