The replica IW371752 is a copy of an IWC chronograph from the 3717 reference family, built with a stainless steel case, sapphire crystal, and a working chronograph. Quality ranges from cheap quartz lookalikes to super clone automatics that match the original case diameter, dial layout, and date position. Before you buy, match the version you are offered against the genuine reference specs, since no two factories build the same watch.
What is the IW371752 originally?
The reference belongs to an IWC chronograph line known for a brushed and polished steel case in the 41 to 42mm range and a tri-compax or two-register dial, depending on the version. IWC pairs these chronographs with an automatic movement and a sapphire crystal with anti-reflective coating on both sides.
Dial color, subdial placement, and date window position change between variants in this family. That matters for replica buyers, because a factory that copies one dial layout often reuses the same case for several references, and small mismatches show up fast in photos.
Which details separate a good replica IW371752 from a poor one?
Case and crystal
A strong version keeps the case profile thin at the lugs and bevels the edges so light catches them the way the original does. Check that the crystal sits nearly flush with the bezel instead of domed above it.
Look at the crown and pushers: they should sit square, screw down smoothly, and line up with the case center. Crooked pushers are the single most common flaw on budget copies.
Dial and subdials
Printed text should be crisp at macro distance, with no fuzzy lettering or thick, blobby numerals. Subdial hands must reach the printed track, and the subdials themselves should sit on the correct vertical axis.
Ask for a photo of the dial in daylight, not just studio shots with heavy lighting. Sunray finishes hide flaws under bright light and expose them in shade.
Movement
Most replicas in this reference family use one of four setups: a quartz module, a Seagull ST19 hand-wound chronograph, an A7750-based automatic with a chronograph module, or a clone automatic built to imitate the original calibre. The A7750 family is the most common choice at mid and high tiers.
Ask whether the chronograph resets to zero in one clean snap. A sticky reset or a jumping seconds hand means the module needs service or the movement is low grade.
Strap and clasp
Leather straps on replicas are usually the weakest part and the cheapest to replace. Check the clasp engraving, the spring bar fit, and whether the strap tapers the way the original does.
How much should a replica IW371752 cost?
- Entry tier, roughly $70 to $150: quartz or basic hand-wound, thin plating, printed dial flaws.
- Mid tier, roughly $180 to $350: automatic chronograph, correct dimensions, decent dial print.
- Super clone tier, roughly $400 to $700: cloned movement, closest case and dial match, best finishing.
Prices below the entry tier almost always mean a quartz watch with a decorative chronograph that does nothing.
Can a replica IW371752 pass as genuine?
No. A watchmaker with a loupe can spot differences in movement finishing, caseback engraving, and dial print within seconds. Treat a replica as a wearable homage, never as an investment or something to resell as authentic.
How do you care for a replica IW371752?
Keep it away from hot water and steam, even if the listing claims high water resistance. Replica gaskets are rarely tested, so swimming is a risk on any tier.
Wind or wear the watch regularly to keep the movement lubricated, and have a chronograph movement serviced every three to five years. Store it on a soft surface so the crystal and case sides do not pick up scratches.
What should you ask a seller before ordering?
- Exact case diameter, thickness, and lug width.
- Movement type, plus whether the chronograph functions are real.
- Dial layout photos in natural light.
- Water resistance as tested, not as claimed.
- Return policy for a dead-on-arrival movement.
