Water resistance: The ability to withstand splashes of water. Terms such as "water resistant to 50 meters" or "water resistant to 200 meters" indicate that the watch can be worn underwater to various depths.




Winding stem: The button on the right side of the watch case used to wind the mainspring. It is also called "crown."

World time dial: A dial, usually on the outer edge of the watch face, which tells the time in up to 24 time zones around the world. The time zones are represented by the names of cities printed on the bezel or dial. The wearer reads the hour in a particular time zone by looking at the scale next to the city that the hour hand is pointing to. The minutes are read as normal. Watches with this feature are called "world timers."
