What the IW544731 Really Is
IWC's Portuguese Tourbillon Mystère is not a watch most people meet in person. Reference IW544731 sits in the Portuguese line, 44 millimeters across, with a flying minute tourbillon hanging in an aperture at 12 o'clock and a seven-day hand-wound movement behind it. Original examples came in platinum and white gold, in runs of a few hundred pieces, at prices that start well into six figures on the secondary market. That gap is exactly why people search for a fake IW544731 in the first place. You want the silhouette, the floating tourbillon, the clean Portuguese dial, without the mortgage.

The catch: this reference is one of the hardest watches to fake well. A tourbillon is not a dial sticker. It is a cage that rotates once a minute, and anyone with a loupe can see whether it rotates at all through that aperture.
What I Check Before Buying
- Movement type. A real tourbillon or a decorated plate that pretends to spin. Under magnification, a genuine cage shows a visible balance inside it, and it moves.
- Case size and thickness. The original is 44mm and fairly slim for a tourbillon. Replicas that stuff a chronograph base under the dial come out three or four millimeters too thick, and it shows at the lugs.
- Dial printing. The Portuguese dial is easy to get wrong. Look at the numerals, the railroad track, and whether the aperture edge is chamfered or simply punched.
- Caseback engraving. Reference number, hallmarks, and the movement finish visible through the sapphire back.
- Hands. Blued steel on the original. Painted blue on cheap reps, and painted blue catches light differently.
My Pick: The Real-Tourbillon Build
If you only buy one, buy the version with an actual hand-wound tourbillon movement, the Seagull ST80 family being the usual base. It costs more than the other options here, sometimes three or four times more, and it is the only one that gets the point of the watch right. The cage rotates once a minute. The aperture reads as a hole with something alive inside it, not a picture of a hole.
Two things to accept with this tier. First, winding feel is not IWC feel. It is a Chinese tourbillon and it winds like one, slightly gritty in the first few turns. Second, service is a genuine question. Most local watchmakers will not touch a tourbillon, so ask the seller about their repair policy before you pay, not after.

Alternative 1: The Decorated-Aperture Automatic
This is the middle tier, an automatic with an open aperture at 12 and a faux cage underneath. On the wrist at arm's length it passes. In the hand it does not. The tell is motion: the cage is either still or wobbles instead of rotating. If you want the look for an evening and you are not handing it to anyone, it works and it saves you real money. If you plan to wear it around people who know watches, spend the extra on the tourbillon version.
Alternative 2: The Quartz Budget Option
Quartz versions exist and they are what they are. Correct dial, correct case shape, no pretense of a tourbillon, and the thinnest and lightest of the three. Good as a beater, or as a size test before you commit to the 44mm case. The seconds hand ticks, so anyone who knows the reference clocks it in about two seconds.
Which One to Order
- Real tourbillon build, if the watch matters to you and the price is workable. Closest match to the original.
- Decorated-aperture automatic, if you want the look on a tighter budget. Accept the compromise.
- Quartz, if this is a size test or a throwaway.
Before ordering, ask three questions: what movement is inside, what the measured case diameter and thickness are, and what happens if the tourbillon stops. A seller who answers all three without hedging is the one to buy from.
