Quick answer
IW328071 is an IWC reference in the Pilot's Watch Automatic 41 family. A replica of this reference sells for about $80 to $600, set by the movement and the dial finish. The genuine watch has a 41 mm steel case, a black dial with lumed Arabic numerals, a date window at 3 o'clock, and a 10 bar water rating. Check case thickness, movement name, and crystal material before you pay. Ask for dated photos of the actual unit.
What the genuine reference is
IWC builds the Pilot's Watch Automatic 41 around caliber 32110, an in-house automatic with a 72-hour power reserve. The case measures 41 mm across and about 11.4 mm thick. Lug width is 20 mm. The crystal is sapphire with an antireflective coating on both faces. Water resistance is rated at 10 bar. The dial carries white numerals on black, a triangle at 12, and a framed date at 3.
IWC does not publish a separate spec page for every dial, case, and strap combination that carries an IW3280xx number. Confirm the build for IW328071 with an authorized dealer before you treat a photo as a benchmark. Treat any seller spec sheet as a claim until you check it.
Parts a replica gets wrong
- Case thickness: replica cases run 0.5 mm to 1.5 mm thicker than the 11.4 mm original.
- Date font: the original uses a narrow, tall numeral inside a thin frame. Replicas use a wide font and a heavy frame.
- Lume: the original dial uses Super-LumiNova. Cheap replicas fade in about 20 minutes.
- Crown: the screw-down crown on the original has crisp threads and a firm stop. Replica threads feel gritty and catch.
- Caseback engraving: depth and text position differ, and the reference line sits off center on many units.
- Bracelet: end links on replicas sit proud of the lugs by 0.2 mm to 0.5 mm.
Movement choices
Three tiers show up in the market. Quartz units cost the least and carry a ticking seconds hand, which the original does not have. Mid-tier units use a Miyota 9015, a Japanese automatic at 28,800 vph with about 42 hours of reserve. Top-tier units use a Chinese clone of the 32110 with a decorated rotor and a closed or open caseback.
The Miyota 9015 is the safe pick. Parts are common, any watchmaker can service it, and it holds time to within about 10 seconds a day. Clone movements look closer to the original and cost more to repair.
Price tiers
- $80 to $150: quartz, mineral glass, stamped caseback.
- $250 to $350: Miyota 9015, sapphire, decent dial print.
- $450 to $600: clone 32110, applied markers, closer case finishing.
Above $600 the extra money buys finish work, not accuracy.
Questions to ask the seller
- What is the movement name and maker?
- What is the case thickness in millimeters?
- Is the crystal sapphire or mineral?
- Can you send photos of the unit I will receive, next to a dated card?
- What is the return window in days, and who pays return shipping?
- Is the water resistance tested or claimed?
Legal and shipping notes for US buyers
Replica watches carry counterfeit trademarks. US Customs and Border Protection can seize an import, and the buyer loses both the watch and the payment. Selling counterfeits violates the Lanham Act. Shipping services do not refund seized parcels.
Care after delivery
Have a watchmaker pressure test the case before you wear it in water. Replica gaskets often arrive dry or unmarked. Replace gaskets every two years if the watch sees water. Service a Miyota 9015 about every five years.
