Gold plating: A layer of gold that has been electro-deposited onto a metal; its thickness is measured in microns. Predominately used for cases and straps

Grande Sonnerie: A type of repeater that sounds a specific sound for the hours and quarter hours when the wearer pushes the button giving the wearer the time without actually reading the dial.

High-Tech Ceramic: Used as a protective shield for spacecraft re-entering the earth’s atmosphere, high-tech ceramic is polished with diamond dust to create a highly polished finish. Because the ceramic can be injection molded, pieces can be contoured. It has a very smooth surface and is usually found in black, but can be produced in a spectrum of colours. Most recently used in the new Rolex Pepsi (see featured image).

Horology: The science of time measurement, including the art of designing and constructing timepieces including clocks and watches.

Index: An hour indicator on an analog watch dial, used instead of numerals keeping the dial clean.

Jump Hour Indicator: A jump hour indicator takes the place of an hour hand. It usually shows the hours by means of a numeral in a window so shows time with only one hand indicating minutes.

Lap Memory: The ability, in some quartz sport watches, to preserve in the watch’s memory the times of laps in a race that have been determined by the lap timer. The wearer can recall these times on a digital display by pushing a button.

Lap Timer: A chronograph function that lets the wearer time segments of a race. At the end of a lap, he/she stops the timer, which then returns to zero to begin timing the next lap.

Limited Editions: A watch style manufactured a specific amount, often numbered, and available in limited quantities. Limited editions are available from most fine watch manufacturers and are usually highly prized by collectors.
