A bold, fully open-worked automatic made to show off its mechanics. The Oupinke 3278 skeletonises the whole dial — the gear train, the bridges and the open-heart balance wheel are all on view through a domed crystal, laid out in a clean, architectural arrangement rather than a cluttered one. The caseback is engraved “Designed by Simone Mazzucato,” and the case sides carry four pusher buttons for the calendar.
Inside is a self-winding automatic movement (24 jewels, 28,800 vibrations per hour) with a decorated rotor visible through the exhibition caseback. The multi-level dial carries four displays — day-of-week, date, month and year — each on its own sub-dial or window, plus luminous hands and markers that glow green in the dark.
The 43 mm case is 316L stainless steel, 12 mm thick, on a solid steel bracelet with lug-mounted adjustment pushers and a dual brushed-and-polished finish. Choose silver/blue, silver/black, all-black, gold-tone, gold/black two-tone, or all-gold-tone.

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 day, date, month and year with the side pushers — 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-worked skeleton automatic with an open-heart balance wheel on show. That’s not a tourbillon, which is a rotating escapement cage found in watches costing far more. This watch does not have a tourbillon.
Is it automatic?
Yes — a self-winding mechanical movement (24 jewels, 28,800 vph), no battery. It also winds by hand via the crown.
Do the calendar displays adjust automatically?
No — the day, date, month and year are set by hand using the crown and the four side pushers. It’s a multifunction calendar, not a self-adjusting perpetual calendar.
What’s the crystal?
A domed mineral glass with a scratch-resistant finish. (It is not sapphire on this model.)
Is the gold version real gold?
No — the gold and two-tone finishes are gold-tone plating over stainless steel.
Can I swim with it?
No. It’s rated 50 m for rain, handwashing and daily splashes only — not for swimming, showering or diving.
