A watch timing machine or timegrapher is a machine that acoustically measures the ticks of a mechanical watch to assess its accuracy and enable calibration.
Most Wave Ceptor watches have a signal strength indicator which shows if the time signal is strong enough to correct the time set. The number of transmitters to which the watches can tune vary according to watch model; most watches can tune to any one of several time signal broadcasts around the world.
This is called a limited calibration. But if the final measurement requires 10% accuracy, then the 3% gauge never can be better than 3.3:1. Then perhaps adjusting the calibration tolerance for the gauge would be a better solution. If the calibration is performed at 100 units, the 1% standard would actually be anywhere between 99 and 101 units.
Tachymeter scale on a Citizen watch bezel. A tachymeter (pronounced / t æ ˈ k ɪ m ə t ər /) is a scale sometimes inscribed around the rim of an analog watch with a chronograph.It can be used to conveniently compute the frequency in inverse-hours of an event of a known second-defined period, such as speed (distance over hours) based on travel time (distance over speed), or measure distance ...
Another early form of electronic speedometer relies upon the interaction between a precision watch mechanism and a mechanical pulsator driven by the car's wheel or transmission. The watch mechanism endeavours to push the speedometer pointer toward zero, while the vehicle-driven pulsator tries to push it toward infinity.
1928 Longines Wrist-Chronograph with the 1925 modified Cal. 13.33Z Flyback function. The oldest Flyback Chronograph in existence, to be seen in the Museum of Longines. [1]A flyback chronograph is a watch complication, in which the user can use a reset function without the need to first stop the chronograph, by a single press on an additional pusher at the 4 o'clock mark.
This audio signal allows the pilot to concentrate on the external view instead of having to watch the instruments, thus improving safety and also giving the pilot more opportunity to search for promising looking clouds and other signs of lift. A variometer that produces this type of audible tone is known as an "audio variometer".
IMAX is a proprietary system of high-resolution cameras, film formats, film projectors, and theaters known for having very large screens with a tall aspect ratio (approximately either 1.43:1 or 1.90:1) and steep stadium seating, with the 1.43:1 ratio format being available only in few selected locations.
