Buy the movement first, the dial second, and the strap last. On an IW371704 copy, the chronograph function, the case silhouette, and the day and date alignment decide whether the watch reads as convincing at arm's length. Ask for photos of the exact unit you will receive, confirm which production tier it comes from, and compare sellers on the parts that cannot be swapped after delivery.

iw371704 Fake Rolex: What You Need to Know

What an IW371704 Copy Is Trying to Reproduce

The genuine reference is a stainless steel IWC chronograph from the pilot watch family, built on a movement derived from the Valjoux 7750 architecture, with a day and date window at 3 o'clock and a two register layout on the dial. Copies chase four things: the case profile and bezel finish, the matte dial texture with its printed minute track, the legibility of the hands and lume, and the feel of the pushers. A decent copy gets the silhouette right. A strong copy also gets the pusher travel, the rotor behavior, and the date font right.

What to Look For

• Case. Check the diameter, the thickness, and the lug shape against reference photos. Brushed and polished surfaces should meet on a defined line, not fade into each other.
• Dial. Look at the printing under magnification. Crisp numerals, even spacing on the minute track, and a flat matte finish separate the good examples from the rest.
• Hands and lume. The hands should sit at the correct height above the dial, with no shadowing from a bent mount. Lume should be applied inside the frame, not smeared over it.
• Day and date. Alignment inside the window matters more than the font on most copies. Ask for a photo of the date at a two digit number.
• Chronograph. Start, stop, and reset should feel firm. A mushy reset or a second hand that snaps back past zero points to a low grade movement.
• Crystal and coating. The crystal should be sapphire or a close substitute with a coating that does not wash the dial out at an angle.
• Strap and hardware. Stitch density, leather thickness, and tang or clasp finish are easy upgrades, so do not let them drive the decision.

Parameter Bands That Matter

Use these ranges when you compare listings, and treat any figure outside them as a warning sign.

copy iw371704

• Case diameter: 41 to 43 mm. A copy that lands outside this range will look wrong next to the genuine article.
• Case thickness: 14 to 15.5 mm including the crystal. A thin case on a chronograph copy points to a quartz substitute.
• Lug width: 21 to 22 mm, matched to a strap that tapers toward the buckle.
• Movement: a 7750 family automatic with a working chronograph and a power reserve in the 40 to 48 hour band.
• Water resistance: treat any claim above 50 m as marketing unless the caseback gasket and crown seals are described.

Common Pitfalls

• Stock photos instead of images of the actual watch. Ask for a timestamped shot.
• Movement claims that do not match the price tier or the visible balance and rotor finish.
• A day and date font that is too wide or too tall for the window, which is the single most obvious tell.
• Buying on price alone. The cheapest listing often skips the sapphire crystal, the decorated rotor, or the correct caseback engraving.
• Ignoring legal risk. Counterfeit watches imported into the United States can be seized and destroyed, and the buyer carries the loss.

FAQ

Do the chronograph pushers work on every copy?

On automatic 7750 based copies, yes. On quartz copies, the pushers usually work but the second hand ticks instead of sweeping, which is an instant giveaway. Confirm the movement type before you order.

IW371704 Replica: What You Get and What to Check

Will an IW371704 copy pass as genuine?

No. Caseback engraving, movement finishing, and dial print will fail close inspection. Treat a copy as a wear item, not an investment, and expect normal service costs if the chronograph needs attention.

Which version should a first time buyer pick?

The mid tier automatic with a working chronograph and a sapphire crystal. It costs more than the entry version but avoids the two problems that force a return: a quartz tick and a crystal that scratches within a month.
