Ingenie is spelled "Ingenieur" in German, and in Japanese the name of a technician is given to the model name. The development of electronic and mechanical engineering in the 1950s increased demand as more people worked in high magnetic forces. Ingenies are said to have been developed for engineers who are exposed to magnetism, such as power station staff and radiographers. The design at the time of the announcement was a simple round type, but in 1976 the design changed completely. Ingenieur SL, created by Gerald Genta, the most renowned watch designer, is still alive as a design concept for the Ingenieur series. In the past, some models boasted a magnetic resistance of 500,000 A / m (6250 gauss), and there is no doubt about their specifications. Ingenia, which had been discontinued at one time, revived in 2005. Not only was the size improved to match the modern age, but the concept changed, and in 2007 a non-magnetically resistant model was derived. It is a model that is very much watched for future trends. We have a lot of used IWC used, such as the representative of such a pilot watch.
