Description
The OUPINKE skeleton automatic is a men's dress-style watch built around an open blue dial, aimed at buyers who like visible mechanics and a bold, jeweled look on the wrist.
It uses a Japanese automatic movement that supports both self-winding and manual winding. The case is stainless steel, 42 mm across and 12 mm thick, covered by a triple-coated anti-reflective sapphire crystal. Water resistance is rated at 50 m.
The dial combines a tourbillon-style layout with a moon phase window, date display and crystal markers, with luminous hands for reading in low light. The tungsten steel bracelet has a rhombus pattern and a hidden butterfly push-button clasp, which keeps the underside clean and the fit secure for daily wear.
Frequently Asked Questions
Can I wear this OUPINKE skeleton watch in the shower?
It is rated to 50 m, which covers splashes, rain and brief contact with water. The maker advises against hot water bathing, so a daily shower is best avoided, since steam can wear on the seals over time. For swimming, choose a watch with a higher rating.
What movement does it use and do I need to wind it?
The OUPINKE uses a Japanese automatic movement that winds itself from wrist motion and also accepts manual winding. If it has been off your wrist for a few days, a few turns of the crown help it start smoothly. The listing names no specific calibre.
Will a 42 mm case fit my wrist?
The case is 42 mm wide and 12 mm thick, with 20 mm lugs. That suits most average to larger wrists. The tungsten steel bracelet weighs the watch at 158 g, so slimmer wrists may notice the heft. Check your bracelet length before buying.
Is the sapphire crystal worth it on a skeleton watch?
Sapphire resists everyday scratches far better than mineral glass, which matters on a watch worn daily. This one has triple anti-reflective coating, which cuts glare and helps you read the open dial and moon phase window under bright light.
How does it compare with a standard three-hand automatic?
A standard automatic has a quieter dial. This OUPINKE adds a skeleton layout, a moon phase window, a date display and a tourbillon-style look, so it is more visual. The trade-off is a modest 50 m rating and an unnamed calibre.
Can the bracelet be resized and is the clasp secure?
The tungsten steel bracelet closes with a hidden butterfly push-button clasp, which keeps the fit secure during daily wear. Link removal on tungsten is harder than on steel, so resizing is best done by a watchmaker or jeweler with proper tools.
Editor's take
OUPINKE's skeleton automatic sits in the fashion-forward corner of mechanical watches, where the appeal is a visible, busy dial rather than a heritage name. The blue open-worked face carries a tourbillon-style layout, a moon phase window and a date display, all under a sapphire crystal. It suits someone who wants a showy mechanical piece at an approachable level.
The drive comes from a Japanese automatic movement that supports both self-winding and manual winding, which is handy if the watch sits in a drawer for a few days. The stainless steel case is 42 mm wide and 12 mm thick, so it wears with real presence. Luminous hands and crystal markers keep the dial readable despite the skeletonized layout.
The main limit is water resistance. At 50 m, it handles splashes and brief immersion, but it is not meant for swimming or hot showers, and the listing says as much. The tungsten steel bracelet is hard and scratch-resistant but heavy, with the watch weighing 158 g, and the hidden butterfly clasp limits quick sizing changes. No caliber is named, which matters to buyers who care about service history.
This is a fit for buyers who want a bold dress-style mechanical on a modest budget and will wear it mostly at a desk or out for dinner. Those who want a documented movement and stronger water resistance should look at entry-level Japanese or Swiss automatics from established brands.

From the manufacturer

42mm Stainless Steel Case
The 42.0mm case is machined from stainless steel, a size that sits comfortably on most wrists without crowding the sleeve. Steel suits daily wear well, resisting knocks and taking a clean finish that holds up over years of use.

Automatic Movement Inside
An automatic movement winds itself through the motion of your wrist, so there is no battery to replace and no crown winding needed during regular wear. Wear it daily and the mainspring stays charged. If it rests for a day or two, a few turns of the crown or a short stretch on the wrist brings it back.

Sapphire Crystal Face
The dial is covered by sapphire crystal, which ranks 9 on the Mohs scale and resists the fine scratches that cloud mineral glass. It keeps the dial legible and clear, even after years of contact with desks, door frames and keys.

Tungsten Strap Construction
The strap is made of tungsten, a dense material with real weight and strong scratch resistance. It gives the watch a solid, balanced feel on the wrist and keeps its polish far longer than softer metals. Expect a heavier presence than a typical steel bracelet.

50m Water Resistance
Rated to 50 meters, the case handles rain, hand washing and accidental splashes without concern. It is not intended for swimming, diving or hot showers, where pressure and steam can compromise the gaskets. Keep the crown pushed in for best protection.

Built for Daily Wear
Steel case, sapphire crystal, tungsten strap and a self-winding movement make a practical combination for a daily watch. Each part is chosen for durability, and the whole is easy to live with. It suits collectors adding a robust everyday piece as well as first-time automatic owners.
