A replica IW545194 is worth buying only if it copies the features that define the reference: a slim hand-wound case of roughly 44 mm, a clean dial with small seconds at 6 o'clock and no date window, leaf-shaped hands, and a solid engraved caseback. If the seller's photos show a date aperture, a 40 mm case, or a glass back, the watch is not a IW545194 replica and the listing is mislabelled. Use the checks below in order. They take about 15 minutes and will separate a serious build from a dressed-up quartz watch.
Before you start
- Close-up photos of the genuine reference: dial, caseband, caseback, buckle
- Digital calipers
- A loupe or a phone macro lens
- The seller's return terms in writing
Step-by-step checks
- Measure the case across the bezel at 3 and 9 o'clock, crown excluded, and compare with the reference figure of about 44 mm.
- Measure case thickness. A genuine hand-wound Portugieser profile is thin; a replica that adds 2 mm looks slab-sided on the wrist.
- Look at the dial: small seconds subdial centered at 6 o'clock, applied numerals, no date opening anywhere.
- Compare the printed dial text with a reference photo at the same image size. Font weight, letter spacing, and the position of the printing relative to the subdial are where cheap replicas fail.
- Check the hands: leaf shape, correct length, minute hand reaching the minute track, subdial hand short enough not to overrun its scale.
- Inspect the crystal edge. It should be sapphire with a slight dome and a clean bevel, not flat mineral glass with a visible milky rim.
- Turn the watch over. The caseback must be solid steel with engraved reference, case number, and brand text. Engraving depth should be crisp, not laser-etched and shallow.
- Wind the crown slowly for 20 turns and feel for grit or a slipping ratchet. Then watch the small seconds hand: it must sweep smoothly. A hand that jumps once per second means a quartz movement.
- Pull the crown to the setting position and check that the hands align exactly at 12 and that the subdial hand sits at zero.
- Examine the strap and buckle: stitching pitch, leather thickness at the lugs, and engraving on the pin buckle. Loose thread and soft chrome-plated buckles are the usual tells.
- Weigh the watch. A steel case of this size should feel substantial in the hand; anything suspiciously light points to a plated alloy case.
Red flags
- A ticking seconds hand or a battery hatch in the caseback
- A date window or a central seconds hand
- Case diameter under 43 mm or over 45 mm
- Display caseback on a reference that used a closed back
- A seller who refuses macro photos of the dial printing and caseback engraving
Living with it
Wind it at the same time each day rather than letting it stop, keep it away from water regardless of any stated water resistance, and have the movement cleaned every three to five years. Store it flat with the strap relaxed so the leather does not crease at the lugs. Treated this way, a good replica of this reference reads correctly on the wrist for years, and the dial layout stays the reason to own it.
