To sum up, Shubo titanium gold has the advantages of scratch resistance, ultra-light, low sensitization and corrosion resistance.
Specific explanation ↓
Specifically, if we want to trace back to titanium, relevant data show that it was discovered in 1795, but it was not used until 19 10 years later. Titanium is widely used in many products, such as spectacle frames, golf clubs, ice axes, wedding rings, cooking pots, dental implants and so on, because of its light weight and skin-friendly characteristics. At the same time, because it is very soft and difficult to process, it is usually not used in products that need careful production, such as watches. In this respect, Citizen is indeed one of the few companies that realized the exploitability of titanium in the early stage, and among these few companies, Citizen developed Shubo Titanium.
Shubo Titanium developed by Citizen is a material that makes titanium harder, more beautiful and more comfortable on the basis of retaining all the advantages of titanium. Many people who wear watches know that if they are worn for a long time, they will inevitably bump. Coupled with natural aging, they will become black and old. What we want to talk about here is the first advantage of Shubo Titanium, "scratch resistance". After long-term and frequent wearing, the watch case and strap made of Shubo titanium gold will not be scratched, and they will remain as bright as new even after long-term use. This hardness is more than five times harder than the stainless steel used in most watches! Since stainless steel is compared, let's talk about the second advantage of Shubo Titanium, "ultra-light". Shubo titanium is about 40% lighter than stainless steel, so it won't feel oppressive when worn on your wrist. It's really light ~
Next, the third advantage of Shubo Titanium is "corrosion resistance". Washing your hands, getting wet in the rain or love sweating in summer will make your watch slowly rust and corrode. After the corrosion experiment in Citizen City, it was found that the corrosion resistance of Shubotai was better than that of stainless steel, which is generally considered to be corrosion-resistant. The last one is "hypoallergenic", which means that it is not so easy to cause allergies. Why put this at the end? Because I am allergic to metals (crying). You can't wear this at ordinary times, and you won't wear it if it itches. So how friendly this material, Shu Botai, is to people who are allergic to us, you mortals may not realize it!
Above, I hope my explanation is not so rigid and easy to understand. If you want to buy Citizen, you can pay attention to this kind of watch. Behind many unfamiliar names, there are actually great talents hidden ~
