The art of making time stands stillThe word chronograph derives from the Greek words chronos and graph meaning time and writing respectively. By definition, the chronographic function is fundamentally that of measuring the duration of a particular event. This instrument, known as a Chronograph, was invented and subsequently patented by Rieussac, the famous Paris watchmaker to King Louis, in 1821. Of course, watches capable of similar functions existed before this date but their precision left a lot to be desired. Rieussac's idea was to create an instrument that could not only give precise timings of horse races but also record the results. The ink chronograph was a device made up of two parts: the lower part held a chamber for the ink while the upper part was fitted with a fine needle that, when activated, pressed on the lower part thus allowing for the ink to flow. The line traced on the face, marked so to speak, the time. Greatly valued within the world of watches, the chronographic functions immediately found a wide range of uses. In short, the many ways in which it could be used made it indispensable not only for timing, but also for measuring speed and distance. The possible fields in which the Chronograph can be used are varied: from sporting events to competitions, from displays of various types to the calculation of production times. The story of the Chronograph entwines also with that of the medical world where it is also used for measuring heart rates. The first Chronographs were fitted with a continuously moving needle. The re-setting mechanism was invented in 1844 by the Swiss watchmaker, Adolphe Nicole, who had emigrated to London. In 1862, once he had duly patented his invention, he presented it a an exhibition in London under his trademark of Nicole et Capt. This new system allowed for the re-setting of the needle of the chronograph thus facilitating successive measurements. The chronograph has been the subject of much research. After the important changes brought about by Nicole's invention another significant step forward was made in 1870 thanks to the French watchmaker Joseph Thaddeus Winnert, who, after years of research, managed to create a chronograph with two hands. The mechanism allowed for the simultaneous measuring of two events of different duration and was also capable of recording two different times and intermediate times: the rattrapante (split seconds) function was born. The first chronographs of this genre were activated by two buttons: one for the start/stop commands and for the re-setting of the first hand, the other for activating the rattrapante system (the second hand). When the chronograph was in use, the second hand could be stopped while the first one continued with the possibility of reactivating the second hand if necessary. The second generation of rattrapante chronographs were created also as wrist watches. They were fitted with three different buttons: one for the start/stop commands, one for re-setting and another (normally on the button for winding) for the rattrapante function. To meet with the requirements of the medical and emergency services sectors, Spencer has, thanks to collaboration with a famous Japanese company, created a chronograph fitted with a pulse meter and a respiratory meter. The chronograph has fascinated entire generations and will continue to do so, not only for collectors and experts, but also for the vast public made up of professionals and enthusiasts. The modern chronograph, a synonym of dynamism, has acquired immortality.
Emergency Room Watch
Wrist chronographsThis Emergency Room Watch is completely new and original. Its distinctive characteristics are those of the button for winding and the spring action buttons that have been re-positioned on the left thus allowing gloves to be worn without the risk of them being torn. The tonneau shaped watchcase, is in polished steel, with well proportioned shapes that integrate with the wrist strap. Above these is a lunette with a tachometer, scale 1000, inscribed on it. Under convex and shockproof glass is the black dial with pointers. Outside these there are a pulse meter scale, base 15, on a red background and a respiratory meter scale, base 15, on a blue background. Three supplementary dials indicate the minutes, the hours and the seconds. Between the hours 7and 8 there is a calendar with the numbers in black on a white background. The plated, dauphine type hour needles are luminous and there are arrows to indicate the seconds.
Internal face diameter: 32 mm [1.25 in].

Records the pulse thus rendering easier the reading of the pulse/minute and the heart rate. The pulse rate is shown directly on the dial on a specific scale which allows for the counting of the pulse according to their rhythm (15 pulsations) based on the movement of the chronograph.
This often comes together with the cardiac scale and allows for the calculation of the breaths/minute rate: a very useful function in the fields of emergency medicine and sport.
