What is the IWC IW545113?
The IW545113 belongs to IWC's Portugieser Hand-Wound Eight Days family, a 43mm stainless steel watch with a silver-plated dial, applied gold numerals, feuille hands and a small seconds subdial at 6 o'clock. The genuine watch runs calibre 59210, a hand-wound movement rated for an eight-day or 192-hour power reserve, with the reserve scale printed on the caseback. Replica versions of this reference copy the silhouette, not the engineering.
Expect the same overall footprint and dial layout on a copy, but a movement that runs about 38 to 42 hours and needs winding every second day.
Which specifications should you verify first?
Numbers filter out weak replicas faster than photos do. Ask for caliper shots and a movement photo instead of catalog renders.
- Case diameter: 43.0mm on the original; many copies measure 42mm or 44mm.
- Case thickness: about 11.5mm; bulky 13mm cases usually hide a thick automatic movement.
- Lug width: 22mm, which matters when you order a replacement strap.
- Crystal: domed sapphire with inner anti-reflective coating.
- Caseback: display back with an engraved reserve scale and reference number.
How do replica grades differ?
Most listings fall into two tiers. The mid tier uses a decorated automatic such as a Miyota 9015 or a Seagull clone, adds cosmetic bridges, and sells for roughly $150 to $300. The top tier attempts a hand-wound layout with deeper engraving and blued screws, and runs $350 to $600 depending on the dealer.
No replica reproduces the eight-day reserve or the differential gearing that drives the genuine indicator. Any listing claiming a true 192-hour reserve at a replica price is inaccurate.
Movement reality check
The 59210 beats at 4 Hz and uses two mainspring barrels in series. A copy with the same external layout still stores far less energy, so the caseback gauge is often decorative or tracks only the first day or two.
What dial and case details give a copy away?
Small printing and finishing cues carry most of the visual weight on this reference.
- Spacing and weight of the brand name and city line on the dial.
- Depth and ring height of the small seconds subdial.
- Polish on the applied numerals and the sharpness of the feuille hands.
- Brushing direction on the lugs and the bevel where brushing meets polish.
- Crown shape, engraving depth, and how cleanly it seats against the case.
What is a reasonable price, and what should you avoid?
Pay according to the movement, not the marketing language. Listings that promise sapphire, an eight-day reserve and Swiss assembly under $300 are misrepresenting at least one of those claims. Skip sellers who refuse quality-control photos, hide the movement under a solid caseback, or offer no return window.
Legal and ownership considerations
These watches are unlicensed copies that infringe registered trademarks, so import and resale can lead to customs seizure and civil liability. A copy also has no manufacturer warranty, no parts support and almost no resale value. Buyers who want the eight-day reserve, service history, and long-term value need the original.
Frequently asked questions
Does the replica IW545113 have an eight-day power reserve?
No. Copies typically run under two days on a full wind, and the indicator on the back rarely reflects real remaining energy.
What strap size fits the replica IW545113?
The lug width is 22mm, so any 22mm strap fits once you match the spring bar thickness to the lug holes.
Is a replica IW545113 worth buying?
Only if you accept the legal exposure and the movement limits. A comparable microbrand dress watch with a serviceable hand-wound movement usually holds up better over several years.
