How do you attract buyers without launching a brand-new product? One way is to add a bit of bling to an existing product, and OnePlus has done just that. The company today launched the Watch Cobalt Limited Edition in India. This is simply the OnePlus Watch, but with a new cobalt alloy in place of the stainless steel body. OnePlus says this alloy is twice as hard and more corrosion resistant. Even the screen gets more protection with the use of sapphire glass. Apart from the aesthetic changes, the rest of the features and specs remain the same. The OnePlus Watch Cobalt Limited Edition costs ₹19,999, and will be available starting July 16.
