The pulsimeter scale shows, at a glance, the number of pulse beats per minute. The observer releases the chronograph hand when starting to count the beats and stops at the 30th, the 20th or the 15th beat according to the basis of calibration indicated on the dial.
Scale on the dial, flange, or bezel that, in conjunction with the second hand, may be used to measure a pulse rate. A pulsometer is always marked with a reference number; if it is marked, for example gradue pour 15 pulsations then the wearer counts 15 beats of a pulse. At the last beat, the second hand will show what the pulse rate is in beats per minute on the pulsometer scale.
Abbreviation of Physical Vapor Deposition, a plating process consisting of the physical transfer of substance by bombardment of electrons.
A watch with five beats or more per second or 18,000 per hour.
Timekeeping’s technical revolution found its way to the world’s wrists in the late 1960s. This was a principally Swiss invention – the first working quartz wristwatches were manufactured by Girard-Perregaux and Piaget as the result of an early joint venture within the Swiss watch industry, but the Japanese (primarily Seiko) came to dominate the market with new technology. The quartz movement uses the famously stable vibration frequency of a quartz crystal subjected to electronic tension (usually 32,868 Hz) as its norm. The fact that a quartz-controlled second hand jumps to the tact of each second is a concession to the use of outside energy.
