A Complete Guide to Super-LumiNova Watches
Luminous watches have been in existence for quite a while now. People who are less knowledgeable or familiar with the watchmaking world and its many terminologies will probably see lume as just another element that makes for a decent timepiece. Little do they know that there was a period when watch illumination was perceived as one of the most technologically advanced developments in horology. Given its long history, this cutting-edge invention has evolved throughout the decades to become what it is today: an integral component in most timepieces.
At present, watch manufacturers typically partner up with illumination firms when it comes to the supply of luminous pigments for their watches. A prime example of this is Super-LumiNova, which happens to be the go-to of many renowned timepiece manufacturers. As such, they are also known as one of the most popular lume companies in the industry. Today, we will take a look at their origins and know-how, along with a specially curated list of the best Super-LumiNova watches available in the market.
A Brief Background on Lume Watches
The first appearance of luminous timepieces dates back to around 1910. These watches were in high demand because many of the armed forces needed timepieces that were readable in the dark during the first World War. The resulting glow was the product of a radium and zinc sulfide mixture which, today, is known as a radioactive and highly dangerous compound. Unfortunately, the hazardous nature of the mixture was only discovered when many of the exposed workers experienced negative side effects, which even led to a couple of deaths.
One would think that these manufacturers learned their lesson regarding hazardous chemicals, but after the radium and zinc sulfide mixture was phased out, it was replaced with another radioactive material called tritium. While it does sound intimidating, it should be noted that tritium is actually not as harmful as the original compound used for luminous coatings. This is why tritium was heavily utilised for a while despite being radioactive. It was only in the 1990s that safer alternatives, such as photoluminescence and electroluminescence, emerged and became more prevalent.
Lume Application: Where and How?
When it comes to watchmaking, luminous coatings are typically applied on the following components of the watch: dial, hands, hour markers, bezel, and others. This is primarily because the main purpose of the lume has always been to allow for better readability in dark environments. In terms of the application of the lume proper, manufacturers and professionals usually opt for pad printing with the occasional hand painting in some cases.
History of Super-LumiNova
Super-LumiNova’s origins date back to the 1940s, during the Second World War. Kenzo Nemoto, who ran his own luminous painting business, was providing his services to the Japanese military. After the war, he began applying luminous coatings to clocks and watches, which led to the establishment of Nemoto & Co. Come 1993, after years of research, and the company came up with the LumiNova, which utilised a new pigment technology called phosphorescence.
Nemoto & Co, having patented this invention, was authorised to give out licenses to other manufacturers for the production and distribution of LumiNova. As such, the Swiss brand RC Tritec AG acquired the right to manufacture said luminous product under the name Super-LumiNova in the same year.
All About Super-LumiNova
Super-LumiNova is a Swiss-made illumination product that many watch brands use today. Unlike the original luminous coatings created in the early 1900s, Super-LumiNova does not contain any radioactive chemicals. This makes it a lot safer for both the manufacturer and the customer. Using 100% Swiss materials, Super-LumiNova pigments boast a high resistance to many environmental changes and meets the REACH criteria set by the European Chemicals Agency. Super-LumiNova is actually manufactured and sold in powder form that’s available in different qualities and colours, all of which we will discuss in further detail below.
How does it work?
The simplest way to explain the technology behind Super-LumiNova pigments is by comparing them to a storage battery charged by light. When the luminous material is exposed to light, be it natural or artificial, it is activated, which then allows for light emission. This phenomenon is called photoluminescence and it revolves around the interaction between an electron and a photon. Moreover, Super-LumiNova uses a material known as strontium aluminate which emits a strong glow when charged. In particular, the process that activates Super-LumiNova is a type of photoluminescence called phosphorescence, and this makes use of highly efficient phosphors – which in this case is the strontium aluminate.
Super-LumiNova comes in eight main different afterglow colours, namely: blue, green, violet, white, yellow, orange, pink, and ultramarine. Prior to the release of Super-LumiNova, blue and green were the prevalent emission colours on most luminous timepieces due to factors like eye sensitivity. The launch of this development was a huge deal in the watchmaking world because it allowed for many opportunities, especially in terms of purposeful design. In addition, RC Tritec can also manufacture custom pigments, which is useful for those who have specific hues they want to replicate or match for their watches.
Despite only being established in the 1990s, Super-LumiNova has evolved significantly in the past twenty years. Through consistent research and experimenting, RC Tritec was able to improve their technology, which led to the establishment of different quality gradings of Super-LumiNova. As of today, Super-LumiNova can be acquired in three grades: Standard Grade, Grade A, and Grade X1. The most recently developed of the three, Grade X1, is said to be their highest-performing one yet.
Super-LumiNova (Photoluminescence) vs Tritium Gas Tubes
Super-LumiNova and tritium gas tubes, which are both still used today, utilise different forms of luminescence. Since we’ve already gone through the science behind Super-LumiNova, let us now delve into the dynamics of tritium gas tubes and how they compare to Super-LumiNova’s photoluminescence.
Tritium Gas Tubes
Tritium gas tubes work by locking tritium gas inside a glass tube that has been coated with phosphor. When the tritium gas releases electrons, the phosphor gets excited, which then results in light emissions that can last up to over a decade.
The most obvious similarity between Super-LumiNova and tritium gas tubes can be found in the scientific processes that drive them. Both make use of phosphor, which means certain chemicals need to interact with each other before a reaction, in the form of light emission, occurs.
Super-LumiNova comes in powder form and is typically printed or painted on dials, hands, and hour markers. Meanwhile, tritium comes in the form of gas that is simply encased in a tube, which is usually fitted into the dial. Furthermore, artificial or natural light is needed to charge Super-LumiNova pigments while tritium gas tubes do not require an external source of energy.
