An instrument, esp. a transit or theodolite with stadia wires, for determining quickly the distances, bearings, and elevations of distant objects.
A speed indicator; a tachometer.
Function that measures the speed at which the wearer has traveled over a given distance. The scale is calibrated to show the speed of a moving object over a known distance. The standard length on which the calibration is based is shown on the dial - ex: 100, 200 or 1,000 meters.
a theodolite designed for rapid measurements
A measuring system on the outer bezel that is used to measure speed.
A scale used to measure average speed over a distance, usually with markings on the watch bezel, popular with automobile racers and airplane pilots.
A feature found in some chronograph watches that lets you measure the rate of speed traveled over a measured distance in a particular length of time.
(“Tack IM eh terâ€) Probably the most common additional feature on chronograph watches, a tachymeter (also called a “tachometerâ€) is a dial that enables the wearer to use the watch to compute distance, speed and other measurements.
A watch function that measures the speed at which the wearer traveled by means of a numeric scale on the watch bezel of a chronograph. Frequently used to determine a speed of a car over a measured distance.
Often used in the motor industry to measure the speed of a car over a specific distance. Functions via a scale on the bezel of a chronograph. Average speeds or hourly production rates can be calculated over a period of observation of less than 60 seconds
A device on the chronograph watch that measure the speed at which the wearer has traveled over a measured distance.
Feature used to measure speed in miles per hour (MPH), nautical miles per hour (KNOTS), or kilometers per hour (KPH), using the sweep second hand and the scale on the wall above the watch face.
A watch complication that measures the distance traveled by means of a numerical scale on the watch bezel of a chronograph. Most commonly used to determine the speed of a car over a measured distance.
A scale used to measure units per hour. Commonly found on the bezels of chronograph watches, an event is timed by using the chronograph seconds hand. The hand is stopped when the event ends and the hand will point to the number of units per hour that could be achieved.
A feature found on chronographs which measures the wearer's speed of travel over a pre-determined distance. Also known as "tachymeter".
A feature allowing the wearer to measure speed by using elapsed time against a distance scale built into the watch.
A device on a chronograph watch that measures the speed at which the wearer has traveled over a measured distance.
Also called a "tachometer", it is a feature found on some chronograph watches. A tachymeter measures the speed at which the wearer has traveled over a measured distance. In watchmaking, a timer or chronograph with a graduated dial on which speed can be read off in kilometers per hour or some other unit (see timer).
Function measuring the speed at which the wearer runs over a given distance. The tachometer scale is calibrated to show the speed of a moving object, such as a vehicle, over a known distance. The standard length on which the calibration is based is always shown on the dial, e.g. 1,000, 200 or 100 meters, or - in some cases - one mile. As the moving vehicle, for instance, passes the starting-point of the measured course whose length corresponds to that used as the basis of calibration, the observer releases the chronograph hand and stops it as the vehicle passes the finishing point. The figure indicated by the hand on the tachometer scale represents the speed in kilometers or miles per hour.
Common feature in chronograph watches. Measures the speed over a predefined distance.
("tack IM eh ter") A feature found on some chronograph watches, a tachymeter (also called a "tachometer") measures the speed at which the wearer has traveled over a measured distance.
A tachymeter (also tachymetre or tacheometer) is a kind of theodolite used for rapid measurements and determines, electronically or electro-optically, the distance to target, and is highly automated in its operations. Tachymeters are often used in surveying.
