Product Description
Oupinke 3281 Open-Heart Automatic Watch — Multifunction Calendar, Sapphire
A busy, dressed-up automatic with plenty to look at. The Oupinke 3281 puts an open-heart aperture at the base of the dial, so you can watch the balance wheel swing as the watch winds itself from your wrist — no battery. Around it sit multiple calendar displays: a day-of-week sub-dial, a date-track sub-dial, and a year/month window, framed by applied Roman numerals and baton markers.
Inside is a self-winding automatic movement (24 jewels, 21,600 vibrations per hour) with a decorated rotor visible through the dial opening. A synthetic sapphire crystal keeps the multi-layered dial clear and scratch-resistant, and polished hands with luminous fill keep it readable in low light.
The case is polished stainless steel on a solid three-link steel bracelet with a push-button butterfly clasp — substantial and comfortable. Choose a clean silver case with a black, grey, white or blue dial.

Wearing & care
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. Use the side buttons to set the year, week and date — avoid adjusting the calendar between roughly 8 pm and 4 am, when the gears are engaged. Keep away from strong magnets.
Frequently asked questions
Is this a tourbillon watch?
No. It’s an open-heart automatic — an aperture in the dial exposes the balance wheel so you can see it oscillate. That’s not a tourbillon, which is a rotating escapement cage. This watch does not have a tourbillon.
Is it automatic or hand-wound?
Automatic — a self-winding mechanical movement (24 jewels), no battery. It also winds by hand via the crown if you need to top it up.
Do the calendar dials adjust automatically?
No — the day, date, month and year are set by hand using the crown and side buttons. It’s a multifunction calendar display, not a self-adjusting perpetual calendar.
Is the glass real sapphire?
Yes — synthetic (lab-grown) sapphire crystal, which offers excellent scratch resistance and clarity.
Can I swim with it?
No. It’s rated 50 m for rain, handwashing and daily splashes only — not for swimming, showering or diving.
Where are Oupinke watches made?
Oupinke is a Chinese brand; this watch is assembled in China with a Chinese automatic movement. Its certifications are compliance registrations, not an indicator of Swiss manufacture.
