The replica IW544705 is a copy of the IWC Portuguese Tourbillon Mystère, a hand-wound dress watch with a flying tourbillon at 12 o'clock and a 7 day power reserve scale. A good copy shows a tourbillon cage that spins, sapphire glass on both sides, and a case that matches the original in size and profile. A bad one hides a fixed bridge behind the dial and a quartz movement inside.

What the IW544705 looks like

IWC built this reference around two ideas: a clean Portuguese dial and one visible complication. The tourbillon sits under an aperture in the upper half of the dial. The rest stays quiet, with thin leaf hands and applied markers on a matte silver-white surface.

  • Round case, about 43 mm across, with a slim bezel and curved lugs.
  • Flying tourbillon aperture at 12 o'clock.
  • Power reserve scale listed as 7 days on the original.
  • Hand-wound movement, so there is no rotor and the profile stays slim.
  • Sapphire crystal front and back on the genuine watch.
  • Leather strap with a folding clasp on most versions.

What separates a good replica IW544705 from a cheap one

The tourbillon is the point of this reference, and it is also the part that decides the price. A real carriage with a balance inside costs hundreds of dollars to make. A decorative bridge costs almost nothing at the factory.

Entry tier (under $100)

Expect quartz, mineral glass, and a tourbillon that never moves. Dial text sits off-center, the case runs thick, and the strap feels like plastic. These look wrong from arm's length.

Mid tier ($150 to $400)

You get an automatic movement, sapphire on the front, and cleaner printing. The aperture still shows a fake cage or a plain balance wheel with a spinning weight behind it. The sweep of the seconds hand is smooth, which fools some buyers.

Top tier ($450 and up)

These run a hand-wound tourbillon movement with a carriage that turns once a minute. Case finishing covers brushed flanks and polished bevels. The caseback carries engraved text, and the strap uses real leather.

How do you check a replica before you pay?

  1. Ask for a video with the seconds hand moving and the tourbillon cage turning. Stills prove nothing.
  2. Confirm the case size and lug width in writing.
  3. Read the dial printing. The brand letters, the Schaffhausen line, and the reference number should sit straight.
  4. Ask whether the crystal is sapphire or mineral. Good sellers answer this without delay.
  5. Request photos of the caseback, the crown, and the strap stitching.

Details that separate a close copy from a rough one

Small choices decide how the watch reads on the wrist. Put photos of the copy next to photos of the original and compare them side by side before you commit.

  • Hand shape: thin leaf hands, correct length, tips reaching the minute track.
  • Dial finish: matte silver-white with applied markers on the original, printed markers on cheap copies.
  • Case profile: a slim mid-case, not a slab.
  • Crown: small, signed, with sharp fluting.
  • Strap: tapered, with stitch color that matches the dial tone.

Movement options in a replica IW544705

Three movement types show up in listings. Each one changes the feel of the watch and the cost of a repair.

  • Quartz: thin, light, and wrong. The seconds hand ticks.
  • Automatic: smooth sweep, but the tourbillon is cosmetic.
  • Hand-wound tourbillon: correct feel, 40 to 60 hours of power on many copies against 7 days on the original, and a higher service bill.

None of these movements match IWC's own caliber. Repairs go to a watchmaker who works on Chinese tourbillons, not to IWC.

How does the replica IW544705 wear?

At about 43 mm with long lugs, this is a big watch. It suits wrists of 17 cm and above, and it slides under a shirt cuff with some effort. Weight depends on the movement and the case metal.

Water resistance runs low. Most copies handle rain and hand washing at best, so take the watch off before you swim. Salt water and soap shorten the life of the seals on any budget tourbillon.

FAQ

Is the tourbillon in a replica IW544705 real?

Only on the top tier. Anything below about $400 hides a decorative bridge or an open balance wheel. A real cage turns a full circle each minute and holds the balance and escapement inside it.

Can I service a replica IW544705?

Yes, but pick the watchmaker first. Many shops turn away copies, and parts for Chinese tourbillon movements come from the same sellers who supply the watches.

Is the size the same as the original?

The best copies use the same dimensions as the IWC reference. Lower tiers often add a millimeter or two, which changes how the watch sits. Ask for caliper photos if size matters to you.

What should I budget?

Plan on $450 to $900 for a working tourbillon copy, $150 to $400 for a cosmetic one, and under $100 for quartz. Shipping and any customs fees sit on top of those numbers.

Care tips that keep the watch running

  • Wind the watch at the same time each day and stop when you feel resistance. Overwinding a thin mainspring is a common failure.
  • Keep it away from magnets, phone cases, and tablet covers.
  • Wipe the case with a soft cloth after wear. Skin oils dull the finish and dry out the strap.
  • Service a tourbillon copy every three to five years, or when it starts losing more than a minute a day.

Buy the movement, not the badge. On this reference, the tourbillon cage tells you most of what you need to know about what you are paying for.
