Flieger Friday: Pilot Watches with Full Lume Dial

One of the most important feature for a pilot watch is the presence of bright lume for reading the time in darkness or poorly lit environment.  The original material used for making the hands, numbers and marker, and the triangle at 12’o clock, was Radium.  Radium was highly radioactive and had adverse effects on those manufacturing the dials, as well as wearing the watch.  Radium was replaced with Tritium in the late 1960’s and early 1970’s.  While Tritium was much safer radioactive material than Radium, its properties to glow did not last more than 12.5 years, and still was not 100% safe.  Hence, Luminova was invented in 1993 by Nemoto & Co., Ltd. of Japan as a safe replacement for non-radioactive luminous paints.  Nemoto licensed Luminova technology to RC Tritec AG of Switzerland, whose renamed it to SuperLuminova, which is now adapted by majority of the watch companies.While majority of the pilot watches use SuperLuminova on the dial and hands, there are few watches which reverse this process by applying the entire dial with SuperLuminova and making the hands and numbers in either black color or with different color shade of luminous paint.  In past, Heuer manufactured sports watches with full lume dial, and recently Muhle Glashuette, Chronoswiss, and Fortis. However, currently the best examples of full lume dial is offered by Laco, Aristo, Damasko, and Junkers.
