SAPPHIRE CRYSTAL The Chevé-Box sapphire crystals are the most complicated version of watch sapphires. They have the appearance of Hezalite glass as made in the past. It should be remembered that the hardness of the sapphire crystal is just behind that of the diamond, at about 2000 HV

The design of the ELKA D Series is inspired by a dial created by Ulysse Nardin for the defunct Elka Watch

About the Nato Straps Many people believe that the NATO bracelet is named after the North Atlantic Treaty Organisation (NATO). Therefore, the common story is that the watch was worn by NATO forces, but this is not technically the case.In reality, the name is short for NATO Stocking Number, a term that simply refers to the fact that the bracelet could be purchased in the NATO supply shop.The original NATO bracelet was born in 1973 in response to the British Ministry of Defence's need to provide a highly durable watch strap for the British Army. The MoD's objective was to design a watchband resistant under all conditions. The aim was to overcome the problems encountered with the bracelets of the time: Problems of moisture on the leather in tropical climates, the risk of reflection of the steel bracelet during a military mission, the poor reliability of rubber bracelets, as well as the risk of losing the watch due to the breakage of the spring bars (including those in the buckle).They were only available in the colour admiral grey and were all 20 millimetres wide. The bracelets were made of nylon.
