A faux Portofino on reference IW938 is best bought as a case-and-dial exercise. The top pick is the closed-caseback three-hander: every part you can check in hand, from the silhouette and lug curve to the dial print, handset, crown and strap fit, carries the whole impression, and there is no display back inviting a closer look. The criteria that decide the call are case profile, dial typography and index placement, hand and crown finish, caseback engraving, and how the strap seats against the lugs.
First: pin down what "IW938" points to
"IW938" is a fragment, not a full IWC reference. The Portofino line has moved through several numbering families across the automatic, the chronograph and the hand-wound models, and sellers trim references to fit a listing title. Before you compare anything, request a straight-on photo of the caseback engraving and match the complete number against the maker's published catalogue entry. A reference that cannot be shown on metal is a reference you cannot check.
Fake Portofino Ref IW938 Replica Watch: What to Check Before You Buy
Pros
- You learn which generation of case and dial the replica is copying.
- Engraving depth, font and spacing become checkable details instead of guesses.
- You can put the dial layout next to the correct official photos.
Cons
- A correct reference string says nothing about the watch in the photos.
- Listing images get borrowed, so the engraving shot may not be the actual piece.
- Some sellers keep references vague to avoid a direct comparison.
Use case: this step matters most when you buy from a listing page that shows a truncated reference and a stock image.

Case silhouette and lug curve
A Portofino reads slim, with a narrow bezel and lugs that sweep down from the case rather than jut out. Ask for a profile shot and a wrist shot. On a replica, the common tells are a case that sits too tall, lugs with a sharp inner edge, and a bezel that looks wider than the dial it frames. Compare the lug-to-lug span against the official spec sheet rather than trusting a model name.
Pros
- Visible in photos with no tools.
- A wrong profile is an instant no.
- It tells you how the watch will wear on your wrist size.
Cons
- Lighting and lens choice distort thickness.
- Caseback curvature stays hidden in front-on shots.
- A good profile does not rescue a poor dial.
Use case: your first filter when you have photos only and no return option.
Dial print, indices and the date window
Sharpness is the whole game here. Applied indices should sit level, with edges that catch light in a consistent line. Printing should stay crisp at the height of the letters, not blur into a soft edge. Check the date aperture: it should be cut square, centered on the dial axis, and sit at the same distance from the rehaut on both sides. On a Portofino dial, the spacing between the printed name, the marker ring and the date or sub-dial is where cheaper copies drift.
Pros
- Readable in an ordinary phone photo.
- One glance tells you how the factory handled the dial.
- Easy to compare side by side with official shots.
Cons
- Macro photos hide soft print that shows at arm's length.
- Some sellers retouch images.
- Dial color shifts under different light.
Use case: the deciding section if the watch will be worn with short sleeves and seen up close.
Hands, crown and caseback engraving
Leaf or baton hands should be flat and clean at the edges, with a polish that matches across the set. The crown should be proportionate, sit flush against the case, and carry a logo that is struck rather than printed. On the caseback, engraving should show visible depth and even letter spacing, with reference and serial lines sitting on a clean arc. Brushed or sandblasted finishes on the back should be uniform, with no polished halo around the text.
Pros
- Crown and engraving are hard to fake well.
- These details separate a careful build from a rushed one.
Cons
- Caseback photos are the ones sellers skip.
- Depth is hard to read in flat light.
- A well-engraved back can sit on a weak case.
Use case: use this as the tiebreaker when two listings sit at a similar level.
Option check: three-hander, chronograph or open caseback
Closed-caseback three-hander
Pros
- No movement on display.
- The simplest dial to print well.
- Closest to the Portofino idea of a dress watch.
Cons
- Fewer features to compare.
- Less visual interest for some buyers.
Use case: the pick for a first replica or a daily dress watch.
Chronograph
Pros
- More presence on the wrist.
- Pushers and sub-dials add detail that good workshops handle.
Cons
- More parts to get wrong, including pusher feel and sub-dial spacing.
- A thicker case is harder to hide.
Use case: for a buyer who already owns a plain three-hander, wants a second Portofino look, and will test the pushers on arrival.
Open caseback
Pros
- You can inspect the finish before committing.
- Useful if movement decoration matters to you.
Cons
- The back becomes the weakest point, since finishing and rotor engraving get compared directly.
- A display back invites scrutiny that a solid one avoids.
Use case: for buyers who accept the movement as a look-alike and are not chasing precision.
Inspection order when the watch arrives
- Set the time and date, then check that the hands align at 12 and the date flips near midnight.
- Look at the dial at arm's length in daylight, then under a lamp.
- Run a fingernail along the case edge and lug tops for burrs.
- Check the strap or bracelet fit at the lugs for gaps and rattle.
- Photograph the caseback engraving and compare it with the official reference photo.
Use case: a short routine to run before you leave feedback or start a return.
What to skip
- Listings that will not show the caseback.
- A reference quoted as a fragment with no full number.
- Photo sets with no profile or wrist shot.
- Listings that lean on vague claims about Swiss parts without naming what was changed.
Use case: a quick screen to apply before you spend time comparing details on a watch you were never going to be able to verify.
