I must admit, it works so far, but is so cheapy made. It looked good in the pix. I had purchased a single winder from Regal was far superior and similar in looks, but purchased another automatic watch so I thought a double winder would be better. I wish I had done more looking. the construction on the case is very very thin plastic, so cheezy. Thought of returing it, but my invoice was not included , and another thing, AMAZON sent this in a box that I could have mailed a small calf . Was ridiculous the wasted box. as for the leather interior, I am just wondering what kind of leather, mouse leather? Was made in China........has a strange feel to it.
