Don't buy this brand Olev. Watches last for one month, return window is one month.
Color: Gold and Silver Band White Face, Color: Gold and Silver Band White Face
I want a refund!!! A little over a month of owning this product and it's broken. Really cheap craftsmanship and the return window is only for one month. Please don't buy from this brand Olev. I would assume they know that they're product isn't any good if the return window is only one month.
