Answer first: the IW544733 is a thin, hand-wound Portugieser, and that is exactly what most replicas get wrong. Before you look at dial printing, measure the case thickness and check the caseback. If you see a rotor where a hand-wound movement should be, stop there. Everything else is detail work you can judge after those two tests.
What the real watch is
The IW544733 sits in IWC's Portugieser Hand-Wound line: a 44 mm time-only watch with small seconds at six and no date. Inside is a slim hand-wound IWC calibre, visible through a sapphire caseback. The design language is 1930s pocket-watch styling, a wide clean dial, a railroad minute track, applied numerals, leaf-shaped hands, and a slim bezel that makes the watch wear large for its size. That combination is friendly to a faker in photos and brutal in person, because thin cases and hand-wound movements cost money to copy well.
Case and thickness
Get calipers. The genuine case is about 44 mm across and close to 10 mm thick, which is unusually slim for a watch this size. Most replicas are built around an automatic movement, so they land at 12 mm or more and sit tall on the wrist. Compare the side profile in listing photos against real owner photos. Look at lug shape and how the caseback sits. Check the crown too: it should be signed and should feel solid when wound, not gritty.
Dial checks that matter
- Sub-seconds hand length: it should reach the printed track, not stop short.
- Railroad minute track: crisp, evenly spaced, continuous.
- Applied numerals and hands: sharp edges, no glue, correct color tone.
- Printing: the logo should read cleanly under a loupe, not blur into the dial.
- No date window. A replica with a date is the wrong case.
Caseback and movement
The sapphire back is where copies give themselves away. A real hand-wound calibre has no oscillating weight, and its bridges are shaped and finished with Geneva stripes and polished bevels. Cheap replicas either show a decorated plate over a different movement or, worse, a rotor. Check engraving depth on the caseback ring and the reference and serial text. Laser etching looks flat and grey; proper engraving catches light.
Winding and setting
Wind it slowly. A decent hand-wound movement feels smooth with a defined stop. Grit, grinding, or a crown that wobbles means the tube and stem are cheap. Set the time and watch the sub-seconds for a clean sweep with no stutter. Ask the seller for a short running video with the crown pulled and pushed, not just a still photo.
What to pay and what to expect
Prices for first copy watches cluster in bands, and the band tells you what you are getting. The cheapest tier usually means quartz or a low-grade automatic in a thick case. Mid tier gets you a hand-wound movement, sapphire, and decent dial work. Top tier adds better finishing and a closer case profile. Nobody sells a perfect copy at a bargain price, so treat any listing that promises one as a warning.
Quick checklist before checkout
- Thickness measured, not guessed.
- No rotor through the caseback.
- Sub-seconds hand reaches the track.
- Signed crown with smooth winding.
- Sharp engraving on the back ring.
- Real photos and a running video from the seller.
- Strap quality and buckle finish match the price tier.
Get those seven right and you are buying the best copy available of a watch that is genuinely hard to fake. Skip them and you are buying a photo.
