I have only had the watch for a few days, but Oupinke watches are very high quality. It keeps time very well and serves as an attention grabber. Great value for the money. It isn't easy to determine where it was made, but it is a Chinese company. Don't stop there with preconceived ideas about cheap products and low quality from China. These watches are exceptional, high-end, and dedicated to creating a brand that endures and stands for quality, rather than simply turning a profit. I would put this watch against those that cost 3-4 times as much. If you are a watch enthusiast, they are worth adding to your collection.

Higher quality than I expected, especially for the price. I have recieved lots of compliments, but I have never told anyone what I paid for it. I use it for a daily wear, and when I go out for dinner.

Good Watch - Hard To Adjust Band

The good: Good quality. Keeps accurate time. The not so good: The not so good is not a problem with the watch but a problem with adjusting the metal band. And that is not the band's fault. That's my fault. To adjust the band so it fits the wrist one must take out links in the band. A tool comes with the watch to aid link removal. I just could not do it. So I replaced this band with another metal band that has a quick adjust magnetic closure.
