Skull. evil. boy. Still use more words? Name says everything. Hidden appearance under the stunning complex complex. Not only feast for the eyes, will also deter the soul! New black, creative from scratch Naturally, one would think that Skull Bad Boy, launched by HYT in 2015, is based on skulls. wrong. The idea is actually the new design of fluid around the skull. This opaque black new fluid seems so simple, but it's actually not just a simple cosmetic change, it takes more than 12 months of development time. The black fluid, like the other four color fluids HYT has developed, has its own unique chemistry. These properties affect the properties of viscosity, coefficient of expansion, and UV protection. In order to create this new fluid, everything begins from scratch. Why? Because it creates a fluid that can be conditioned by the HYT movement, it does not adhere to the capillary walls and maintains the meniscus without molecular-level interactions with the elements in contact. This was finally achieved in the fall of 2015 and has since gone through several weeks of testing to confirm its chemical stability. The ultimate challenge to overcome the "dark" In addition to chemical properties, aesthetics is also a consideration. The creation of a black fluid is not without problems: the other colors HYT creates reflect all or part of the light it receives, but black absorbs all the light. This creates the inevitable result: Skull Bad Boy can not read in the dark. "This is a well-thought-out decision," said HYT CEO Vincent Perriard. "There are other solutions that actually make the watch visible at night. However, since 'darkness' is Skull The inherent nature of the Bad Boy, which we want is that style, then let us do the ultimate. The night is an integral part of the dark world, perfect for skulls. Neuchatel - Damascus In line with this new black liquid, HYT hopes to create a unique skull with damascus steel (Damascus steel is commonly used on knives and samurai swords). Dial structure includes two and a half months, decorated with the Paris nail pattern. The time stamps are gothic in color, complementing the rock-solid look of the Skull Bad Boy. The 51mm matte black case is made of DLC titanium, all micro-finished, with a new polished, all-gray gray alligator strap. Velcro design "allows the watch can be adjusted to fixed on the motorcycle leather jacket," Vincent Periyad introduced a smile. Skull coating uses a newly created composite material, which is similar to Damascus steel. Made from a foundry in Neuchâtel, the materials are superimposed up to 256 layers of steel and carbon layers! This material is cast in batches, with five skulls in each batch and no two skulls are exactly the same . Therefore, the two constituent materials set off each other, endless changes. The steel is noticeably gray, while carbon shows the essence of black under the chemical wear-out process. In the unfinished state, there are infinitely small skulls fissures, which shows the complex process experienced in the foundry. HYT flatten the surface, coated with a layer of translucent varnish. All the original Skull watch all the features reserved. Power storage indicator is located in the right eye socket, with the watch 65 hours power storage gradually depleted, the indicator color is darker and darker. The left eye socket with a second disk, always kept rotating, almost hard to detect.
