Short answer
A replica IW323716 copies an IWC Aquatimer diver. The best current builds use a titanium or 316L steel case, a sapphire crystal, a screw-down crown, and an automatic movement at 28,800 vph. Prices run from about $150 for a basic A2824 build to $600 for a high-grade 1:1 version with a titanium case and a clone caliber. IWC does not carry a spec page for every older reference, so confirm case diameter, thickness, and lug width from the seller before you pay.
What the IW323716 reference is
IWC reference numbers in the 3200 block sit in the Aquatimer family, the brand's dive line. The last two digits of a reference mark the dial and strap combination, so IW323716 is one variant inside that block. Aquatimer 2000 models are the deepest of the line, rated to 2,000 m (200 bar) on the genuine watch. Titanium cases are common on those models, along with an inner or outer rotating bezel. IWC fits in-house automatic calibers to these watches. A replica swaps that caliber for a third-party automatic and keeps the outside geometry.
Case and build
- Diameter on Aquatimer 2000 references: 44 mm to 46 mm. Confirm the number for the exact build.
- Case material: titanium on the genuine watch, steel on most replicas. Titanium replicas exist and cost more.
- Crystal: sapphire on top grades, mineral glass on cheap ones. Sapphire with inner anti-reflective coating is the tell.
- Water resistance: replicas are not pressure tested at the factory. Treat any 2,000 m claim as cosmetic.
Movement grades
Three movement grades show up in replica IW323716 builds.
- Asia ETA 2824 clone (A2824). 28,800 vph, 38 to 40 hours of reserve, hacking, hand winding. Entry tier.
- Miyota 9015. Same beat rate, about 42 hours of reserve, smoother rotor. Mid tier.
- Clone IWC-style caliber from Dandong or Shanghai. Decorated plates, engraved rotor. Top tier.
Ask for the beat rate in writing. A 21,600 vph movement inside a watch that should run at 28,800 vph is a visible flaw in a phone video. Ask for seconds-per-day figures too, since clone calibers drift more than a regulated Swiss movement.
Dial, bezel, and caseback checks
- Lume plots: line up with the printed minute track. Misalignment is the most common defect on this reference.
- Date window: centered in the aperture, font matches the genuine dial, no white gap at the edge.
- Bezel action: 60 clicks on a rotating bezel, firm and even. A mushy friction ring is a low-grade part.
- Caseback engraving: sharp edges, correct reference number, no smeared text or shallow laser marks.
- Crown: screw-down, threads catch in one turn, no vertical wobble when pulled to the setting position.
Price bands (USD, 2025)
Low grade, steel, mineral glass, A2824: $150 to $250. Mid grade, sapphire, Miyota 9015: $260 to $380. High grade 1:1, titanium case, clone movement, sapphire with AR coating: $400 to $600. The strap moves the price: rubber sits at the bottom, a titanium bracelet adds $80 to $150.
What a replica cannot match
- The in-house caliber. Rotor noise, winding feel, and service access differ from the genuine movement.
- Titanium finishing. Grade 5 titanium takes a different brush pattern than 316L steel, and the tone is darker.
- Pressure testing. A 2,000 m rating on a replica is a marketing claim, not a test result.
- Parts supply. Genuine crystals, bezels, and crowns do not fit replica midcases.
Questions for the seller
- Case diameter and thickness in mm?
- Movement name, beat rate, and rate in seconds per day?
- Case material, 316L steel or titanium?
- Water resistance test result and test date, if any?
- Photos of the caseback, crown threads, and lume in the dark?
Legal note
Replica watches are counterfeit goods. US Customs and Border Protection can seize them at import under 19 U.S.C. 1526, and similar rules apply in the EU and most of Asia. Factor that risk into any purchase.
