A bold, sporty skeleton in a barrel-shaped case. The Oupinke 3215 takes the tonneau (wine-barrel) silhouette and opens it right up: curved skeleton bridges form an X across the dial, exposing the gear train and balance wheel, framed by a screw-down bezel and a layered case. It winds itself from the motion of your wrist — no battery — and the whole mechanism is on show front and back.
Inside is a genuine Japanese Miyota automatic (21 jewels, 21,600 vibrations per hour, ~40-hour power reserve) — a reliable, widely-trusted movement, visible through the panoramic exhibition caseback. Over the dial sits a curved sapphire crystal that follows the case lines and shrugs off scratches, and the open skeleton bridges are filled with strong green luminous for a dramatic glow after dark.
The 316L stainless steel case measures about 45 × 52 mm and 14 mm thick, riding on a comfortable perforated silicone sports strap with a pin buckle. Choose a two-tone rose-gold-tone and black case, with a black, red or white strap — several combinations in all.

Rated 50 m (5 ATM): fine for rain, handwashing and everyday splashes, but not for swimming, showering or diving — and never operate the crown in water. As an automatic it winds from wrist movement; if left off a day or two it will stop, so give the crown a few turns and reset the time before wearing. Rinse the silicone strap with fresh water now and then, wipe with a soft cloth, and keep away from strong magnets.
Is it a chronograph?
No. The Oupinke 3215 is a time-only skeleton automatic — the open dial shows the movement, but there are no stopwatch pushers or chronograph sub-dials. It tells the time; it does not time events.
Is it automatic?
Yes — a genuine Japanese Miyota self-winding movement (21 jewels), no battery. You can see it through the exhibition caseback.
Is the crystal sapphire?
Yes — a curved synthetic sapphire crystal that follows the case shape, highly scratch-resistant.
Is the rose-gold version real gold?
No — it’s a rose-gold-tone plated finish over stainless steel, not solid gold.
Can I swim with it?
No. It’s rated 50 m for rain, handwashing and daily splashes only — not for swimming, showering or diving.
How big does it wear?
It’s a large, sporty tonneau — about 45 mm wide and 52 mm long — so it makes a statement. Best on medium-to-larger wrists.
