Perpetual Calendar – A highly complicated movement displaying calendar information that adjusts to different lengthen months and years. Perpetual calendars are often among the most valuable, highly sought after watches.







Power reserve indicator: A feature that shows when the watch will soon need a new battery or winding. A battery reserve indicator on a quartz watch informs the wearer when the battery is low. Often this is indicated by the second’s hand moving at two or three-second intervals. Seiko's Kinetic watches are quartz watches that do not have a battery (see Kinetic). When a Seiko Kinetic needs to be wound, the seconds hand will also move in two second intervals.







Pushers or push pieces: Push buttons are on the case of the chronographs and some complicated watches. Most are used to stop and start a stopwatch but sometimes serve other functions. • PVD -physical vapour deposition: A coating of titanium nitrate applied in a vacuum and then covered by a coating of 22k gold to obtain a gold coloured finish.
