A big, high-shine skeleton automatic that wears its mechanics on its sleeve. The Oupinke 3252 surrounds an open-worked, Geneva-striped dial with a bezel set in clear baguette-cut crystals, so it catches the light from every angle. Through the open-heart aperture you can watch the balance wheel swing as the watch winds itself from your wrist — no battery.
The multi-level dial layers 3D Roman numerals over the gear train and packs in the displays: a day-of-week sub-dial, a date sub-dial, and a year/month window. Inside is a self-winding automatic movement (24 jewels, ~45-hour power reserve) with a decorated rotor. A synthetic sapphire crystal keeps the whole busy scene clear and scratch-resistant, and luminous hands keep it readable after dark.
The stainless steel case is a bold 40–44 mm, 13.5 mm thick, on a solid 316L steel bracelet with a push-button hidden clasp. Choose all-black, silver with a black dial, or silver with a grey dial. It ships complete — box, warranty card, manual, strap tool and a gift bracelet.

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 wind the crown and reset the time and calendar. Set the week, date, month and year by hand — avoid adjusting the calendar between roughly 8 pm and 4 am, when the gears are engaged. Keep away from strong magnets.
Is this a tourbillon watch?
No. It’s an open-heart skeleton automatic — an aperture exposes the balance wheel so you can see it oscillate. That’s not a tourbillon, which is a rotating escapement cage found in watches costing many times more. This watch does not have a tourbillon.
Is it automatic?
Yes — a self-winding mechanical movement (24 jewels, about 45 hours of reserve), no battery. It also winds by hand via the crown.
Are the bezel stones real diamonds?
No — the bezel is set with clear baguette-cut crystals for sparkle, not diamonds.
Do the calendar dials adjust automatically?
No — the day, date, month and year are set by hand. It’s a multifunction calendar display, not a self-adjusting perpetual calendar.
Is the glass real sapphire?
Yes — synthetic (lab-grown) sapphire crystal, with excellent scratch resistance.
Can I swim with it?
No. It’s rated 50 m for rain, handwashing and daily splashes only — not for swimming, showering or diving.
