Watch with day & date
Nice watch, light in weight. Looks good with the grey background.
Has the day and date too, just wish they were a little larger, for easier reading.

Es muy elegante
Color: 3316：white band white dial
The OUPINKE Automatic Two-Tone Skeleton Watch is a stylish timepiece that blends luxury design with mechanical craftsmanship. Its gold and silver stainless steel construction gives it an elegant, premium look suitable for both formal and casual occasions.
Design & Appearance:
This watch stands out with its two-tone bracelet and gold-accented bezel, creating a bold and sophisticated aesthetic. The dial features crystal-style hour markers, multiple subdials, and a visible skeleton window at the bottom that showcases the internal movement. These details add a high-end feel often associated with more expensive watches.
Movement & Performance:
It uses an automatic mechanical movement, which means it winds itself through the motion of your wrist—no battery required. This is a major advantage for watch enthusiasts who appreciate traditional watchmaking. The watch also includes useful calendar features such as day, date, and month indicators.
Build Quality:
The stainless steel case and bracelet feel solid and durable. The polished finish enhances its luxury appeal, although like most polished watches, it may show fingerprints or small scratches over time.
Comfort:
Despite its robust design, the watch is comfortable to wear. The bracelet is well-balanced, and the clasp keeps it secure on the wrist.

Exceptional quality
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.

Color: GZ3255Z:Two tone band&Blue dial
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.
