The IW544720 is IWC's Portuguese Tourbillon Mystère, a hand-wound dress watch with a flying tourbillon open at 12 o'clock. A replica IW544720 is a third-party copy of that watch, and the good ones get case proportions, dial printing, and the tourbillon cage right while the cheap ones get all three wrong.
What is the IWC IW544720?
The IW544720 sits in IWC's Portuguese line, the family of large, clean, pocket-watch style dress watches the brand is known for. This reference is a hand-wound tourbillon model, the Portuguese Tourbillon Mystère, and its signature detail is the tourbillon carriage left visible through an aperture in the dial.
Standard listings for the original describe a precious-metal case of roughly 43 mm, applied numerals, and a cage perched on the vertical axis at 12 o'clock. Original production was small and expensive, so most buyers only ever meet this watch in photographs, which is exactly why the copy market exists.
What should you check first on a replica IW544720?
Check the tourbillon cage before anything else. On this model the cage is fully exposed in the dial, so a tilted or off-center carriage is visible from arm's length and it is the fastest tell in the room.
- Cage position: centered in the aperture, level, no tilt at rest.
- Dial printing: sharp and even, no fuzzy scale or bleeding ink.
- Case finishing: crisp bevels, straight lug tapers, no tool marks.
- Caseback engraving: correct reference text, correct font, straight alignment.
Does a replica IW544720 tourbillon actually work?
At the top tier, yes. Some first copy IW544720 builds use a genuine rotating carriage driven by the movement, so the cage turns once a minute as the watch runs. Lower tiers sell an open-heart lookalike where the balance oscillates but the carriage never spins.
That difference is what you are actually paying for, and it is the one claim worth verifying before money changes hands.
Dial, hands, and case details that separate the tiers
On the original, printing is thin and glossy, applied indices sit flat, and the hands are leaf shaped with polished flanks. Strong copies hold that standard. Budget copies use heavier ink, painted rather than applied markers, and hands that look stamped instead of finished.
Case work matters just as much. Look for a polished band with a defined step at the bezel, lugs that taper without a bulge, and a crown with a legible logo. A better strap is the cheapest upgrade any owner can make, and it changes how the watch reads on the wrist more than most dial tweaks do.
How much should a replica IW544720 cost?
Price tracks the movement, not the name on the dial. Working tourbillon builds sit in the high tier, decorative open-heart builds sit in the middle, and quartz or non-tourbillon lookalikes are the cheapest and the easiest to spot.
If a listing prices a working tourbillon at a bargain number, treat the movement claim with suspicion. Ask for video of the cage turning, not a still image.
Quick buying checklist
- Confirm the caseback reads IW544720.
- Request video of the tourbillon cage rotating.
- Compare the dial aperture shape against official photos.
- Note case size and lug width before ordering straps.
- Get the return window and warranty terms in writing.
Frequently asked questions
Is a replica IW544720 a good everyday watch?
It is a dress watch with an exposed movement, so treat it gently. No swimming, no impact, and have it serviced if it starts running fast or slow.
Will people spot a replica IW544720?
Most will not, since the reference is rare and rarely seen. Watch people will study the cage and the dial print, which is why those two zones decide how convincing the watch is.
What size wrist suits it?
A 43 mm case with slim lugs wears well on wrists from about 6.5 inches up. Smaller wrists should see it in person before committing.
